  176. --------------------------------------------------------------------------------
  177. 5. Compilation instructions
  178. First you must download wxWidgets. Audacity 2.1.2 requires wxWidgets 3.0.x,
  179. preferably 3.0.2, which can be obtained from:
  180. .
  181. The libsndfile library is also required and is included in Audacity obtained
  182. from GitHub.
  183. CMake ( ) is required to build the local copy of
  184. the libsoxr resampling library used by Audacity, unless you install
  185. libsoxr-dev and use that system library.
  186. Installation of other libraries is optional, see:
  187. .
  188. If you install libraries using a package management system like Apt or RPM,
  189. you need to install the "dev" (development) packages for each library.
  190. To compile on Linux, Mac OS X and other Unix systems, execute these
  191. commands:
  192. ./configure
  193. make
  194. make install # as root
  195. To see compile-time options you can set, you can type
  196. ./configure --help
  197. If you want to do any development, you might want to generate a configure cache
  198. and header dependencies:
  199. ./configure -C
  200. make dep
  201. To compile on Windows using MSVC++, please follow the instructions in
  202. win\compile.txt in the source code.
  203. To compile using Xcode on Mac OS X, see the instructions in mac/compile.txt.
  204. For more information on compilation, please visit:

  338. now enter the speed change as a multiplier e.g. "2" is twice as fast.
  339. * New "Crossfade Tracks" effect can be used for crossfading two tracks.
  340. This replaces Cross Fade In and Cross Fade Out.
  341. * Nyquist Prompt and most shipped Nyquist effects now have Preview button.
  342. * Interface:
  343. * Redesigned Meter Toolbars: The default shows separate Record and Playback
  344. Meters, half-height so they can be wider while docked, in gradient style.
  345. * A frequency selection can now be made (and spectral edit effects applied

  363. * Analyze > Contrast could report very inaccurate rms levels.
  364. * Noise Removal: Attack and decay times were half as long as set.
  365. * (OS X and Linux) Nyquist effects ran much more slowly than on Windows.
  366. * Click or drag on the Timeline after Loop Play continued to loop.
  367. * Transcription Toolbar did not play slower than 0.1x speed.
  368. * (Linux) Audacity did not build if python 2 was not available.
  369. * Projects did not reopen correctly if they contained tracks having
  370. 2^31 samples or greater of audio (just over 13.5 hours at 44100 Hz).

  372. * Interface:
  373. * Redesigned, searchable Keyboard Preferences with Tree, Name and Key views.
  374. * Edit Menu: "Cut" and "Delete" are now in the top level of the menu.

  382. * "Snap To" settings are now independent for each project.
  383. * Effects:
  384. * Truncate Silence: redesigned with simpler option "Truncate Detected
  385. Silence" to shorten to the specified length without compressing silence.
  386. * VST effects: New "Settings" dialog lets you specify buffer size (for
  387. faster processing) and enable buffer delay compensation (to prevent
  388. inserted silence). Compensation may cause a crash in a few plug-ins.
  389. * VST effects now support standard FXP presets.
  390. * LV2 effects are now supported on all platforms (textual interface only).
  391. * Import or export using FFmpeg now requires FFmpeg 1.2 or later (or libav
  392. 0.8 or later). For recommended downloads of recent FFmpeg please visit:
  393. .
  394. * New Tamil translation (largely complete).
  395. * (Windows) FLAC exports can now exceed 2 GB in size.
  396. * (OS X) Easier Audacity installation using the DMG: drag the Audacity folder

  401. effects in /usr/lib/ladspa.
  402. Changes in version 2.0.5:
  403. Bug fixes for:
  404. * Shaped dither was corrupted and too loud on all stereo exports except FLAC.
  405. * Keyboard Preferences: some Edit and Align commands for different sub-menus
  406. showed the same name.
  407. * Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
  408. * In locales that use comma for decimal separator:
  409. * Text boxes with slider in Nyquist effects only produced whole numbers
  410. when using comma to enter a fractional number. Text boxes without
  411. slider still have this problem.
  412. * Built-in generators produced silence after running a Nyquist effect.
  413. * (Windows) When first changing to Windows WASAPI host, the input volume slider
  414. in Mixer Toolbar was enabled when it should have been permanently disabled.
  415. * (Windows) On some machines, launching Audacity then recording from the current
  416. Device Toolbar input would not record until the input was reselected.
  417. * (OS X) Frequent crashes occurred on importing audio files on some machines.
  418. * (OS X) Files did not open using Finder "Open with", double-clicking the
  419. file or dragging the file to the Audacity icon.
  420. * (Linux 64-bit) Fixed a crash when using Equalization.
  421. * (Linux) It was not possible to open an effect or other dialog then navigate
  422. through the dialog using TAB.
  423. * (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC
  424. import if the warning for importing uncompressed files appeared.
  425. Changes and Improvements:
  426. * Tracks Menu:
  427. * The separate commands that aligned track start or end with the cursor or
  428. with selection start are combined into "Cursor/Selection Start" commands.
  429. * "Align and Move Cursor" renamed to "Move Selection when Aligning".
  430. * Label Tracks:
  431. * Labels Editor now allows empty labels to be saved on closing the editor.
  432. * TAB and SHIFT+TAB when the label track has focus now always move forwards
  433. or backwards respectively to the nearest label.
  434. * (Windows) On a very few machines, the Windows WDM-KS low latency audio host
  435. introduced in Audacity 2.0.4 caused Audacity to hang or the computer to
  436. crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
  437. * (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
  438. * (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded
  439. until chosen from the Effect menu. This should speed up launch and avoid
  440. crashes at launch due to misbehaving Audio Units.
  441. * (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
  442. * (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's
  443. menu bar (or visual corruption under Unity) on Debian-based systems.
  444. Changes in version 2.0.4:
  445. Bug fixes for:
  446. * Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers
  447. were not exported. All imported shortcut changes were discarded.
  448. * Equalization curves were corrupted in Graphic EQ mode after switching
  449. to/from Draw Curves or after running the effect then reopening it.
  450. * Change Pitch displayed corrupted values when reducing pitch or editing
  451. "from" Frequency. Detection was very inaccurate at high sample rates.
  452. * Bass Boost no longer clips if the track contains 32-bit audio.
  453. * Auto Duck was excessively slow on older machines.
  454. * (Windows) Exported MP3 comments tags were not seen by Windows programs.
  455. * (Windows and OS X) Audacity crashed if you used system quit before
  456. file import was complete.
  457. * (Linux) Equalization crashed Audacity if the XML file was corrupted.
  458. * (Linux) When configuring effect parameters in "Edit Chains", "Preview"
  459. (not intended to be functional) caused a crash.
  460. * (Linux) LICENSE.txt and README.txt were wrongly installed in
  461. /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
  462. * Accessibility: ENTER did not toggle selectedness of a label track unless
  463. a label was selected.
  464. * Numerous other interface fixes.
  465. Changes and Improvements:
  466. * New "Reverb" effect to replace GVerb, based on the original "Freeverb".
  467. * New View > Go to Selection Start and Go to Selection End commands.
  468. * New "Align End to End" command to append existing tracks to each other.
  469. * Change Tempo now supports fractional BPM.
  470. * Plot Spectrum now supports FFT sizes up to 65536.
  471. * WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO
  472. tags and also support ID3 tags.
  473. * Handle a bug in older iPods or some OS X applications that cause them to
  474. refuse AIFF files whose metadata contains an uneven number of characters,
  475. * (Windows) Added support for "Windows WDM-KS" host which can provide very
  476. low latencies if you reduce "Audio to Buffer" in Recording Preferences.
  477. * (Windows Vista and later) You can now record computer playback by choosing
  478. the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
  479. * (Windows and Mac OS X): VST scanning dialog now replaced with a dialog
  480. for choosing which VST effects to load.
  481. * (Linux) CTRL + ALT can now be used to smooth samples in Draw Tool.
  482. * Modules Preferences replaced with a dialog on launch of Audacity
  483. enabling you to choose which modules to load.
  484. Changes in version 2.0.3:
  485. Bug fixes for:
  486. * Crash using Undo whilst time-shifting a track.
  487. * Crash using Repair if the selection extended into an empty track.
  488. * Export Multiple didn't prevent export if there was no audio or
  489. all audio was muted. This allowed export of small invalid files.
  490. * Time Track:
  491. * Loop Play of a speeded-up track inserted silence.
  492. * Playback and rendering was significantly inaccurate, creating
  493. audible and visual glitches.
  494. * Accessibility:
  495. * The mnemonics character "&" was read out by screen readers in
  496. most of the Preferences choices.
  497. * NVDA did not read static text in most dialogs. Text can now be
  498. read by using INSERT + B.
  499. * JAWS and Window-eyes misread the "Duration" control in Silence
  500. Generator.
  501. * Toolbar buttons could not be pressed by ENTER
  502. * Other interface bug fixes.
  503. Changes and Improvements:
  504. * The SoX Resampler library (libsoxr) has replaced libresample in
  505. Audacity releases, offering both higher quality and greater speed. .
  506. * Time Tracks new features:
  507. * "Set Range" now changes only the range of the Time Track,
  508. preserving the pitch/speed set by any existing warp points.
  509. * Vertical scale added with options for linear and logarithmic
  510. display and interpolation.
  511. * Upper and lower speed limits will now be remembered when saving
  512. and reopening a project in 2.0.3. Warp points in projects saved
  513. by previous Audacity versions will be correctly restored in 2.0.3.
  514. * Warp points saved in a 2.0.3 project will be preserved if opened
  515. in previous versions but playback and display will be incorrect.
  516. * New effects:
  517. * Studio Fade Out (uses a filtered "S" curve).
  518. * Adjustable Fade (accessible effect for creating partial fades
  519. and adjustable fade shapes).
  520. * Bass and Treble (replaces Bass Boost).
  521. * Real sample rates up to 384000 Hz are now supported for playback
  522. and recording in high resolution devices (the maximum is up to
  523. 192000 Hz for Windows DirectSound host).
  524. * Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now
  525. allows splits to be placed at point labels. Labeled audio regions
  526. that touch without overlapping are treated as separate regions.
  527. Overlapping labeled audio regions are treated as a single region.
  528. * Compilation: cmake is required in order to build libsoxr.
  529. * New Croatian translation of Audacity.
  530. Changes in version 2.0.2:
  531. Bug fixes for:
  532. * Interface:
  533. * "Retain labels" Interface Preference did not retain labels for
  534. a region that snapped exactly to both label edges.
  535. * Projects did not save the track selected state.
  536. * (OS X, Linux) Timer Record: Interlinking of the Start, End and
  537. Duration controls was broken.
  538. * (Windows) JAWS screen-reader did not read the "Draw curves" and
  539. "Graphic EQ" radio buttons in Equalization correctly.
  540. * Envelopes and Clips:
  541. * Exporting (or any render operation) on a track containing
  542. split lines could create clicks at the split lines.
  543. * Dragging a clip into another track caused a crash if Sync-Lock
  544. Tracks was enabled and there was also a label track.
  545. * Effects and Analysis:
  546. * Normalize could crash if the track name contained "%".
  547. Changes and Improvements:
  548. * Duration controls when generating at a point now default to
  549. hh:mm:ss + milliseconds format. Selection Toolbar also defaults
  550. to that format on first installation or resetting preferences.
  551. * Toolbars visual improvements:
  552. * "Snap To" in Selection Toolbar now has an explanatory tooltip.
  553. * Device Toolbar tooltips now display the selected device.
  554. * Increased default width of Device Toolbar and Meter Toolbar.
  555. * Improvements and some bug fixes to Nyquist effects, including:
  556. * Delay (new option to prevent duration change)
  557. * Sample Data Export (new "L-R on Same Line" layout option)
  558. * Risset Drum (new "Amplitude" slider).
  559. * Importing a labels file writes the file name to the name of the
  560. Label Track, and exporting a labels file offers the name of the
  561. last Label Track in the project.
  562. * Removed the "Audio cache" option from Directories Preferences
  563. due to frequent crash reports. All data operations will now
  564. be written to disk and not to RAM.
  565. * Removed the FFmpeg "On-Demand" option from Libraries Preferences
  566. (this fixes Audacity not building if configured --without-ffmpeg).
  567. * Compilation: Progress on making the Modules feature mainstream.
  568. Modules can now be individually enabled and disabled in Preferences.
  569. Changes in version 2.0.1:
  570. Bug fixes for:
  571. * Interface:
  572. * Selection Toolbar: a value for the previous whole second
  573. displayed if the value was close to a whole second.
  574. * Finding zero crossings could cause the selection to expand into
  575. white space at either side of the clip.
  576. * Clips did not drag to another track if mouse was over a selection.
  577. * Mixer Board: Rendering four tracks resulted in a redundant Track
  578. Strip followed by a crash.
  579. * Imports, Exports and Files:
  580. * Exporting to WAV or AIFF led to a "Libsndfile says" error or
  581. corrupted output due to order of metadata in imported files.
  582. * (Mac) Fixed crashes importing MP3 files on PPC machines.
  583. * (Linux Ubuntu) .Aup files could not be associated with Audacity
  584. (they opened in the web browser instead).
  585. * Effects and Analysis:
  586. * Normalize: Fixed issues where normalization could be to wrong
  587. value if applied with DC offset correction, or if applied to
  588. "read-directly" WAV and AIFF files before On-Demand completed.
  589. * Sliding Time Scale: fixed an audible discontinuity at the
  590. beginning of the processed selection; fixed a serious quality
  591. problem on Linux 64-bit.
  592. * Other miscellaneous bug fixes, including fix to prevent zooming
  593. with mouse wheel or ball scrolling the content off-screen.
  594. Changes and Improvements:
  595. * Shortcuts can now be added in Keyboard Preferences to items in the
  596. Generate, Effect or Analyze menus, including user-added plug-ins.
  597. * Nyquist Effect plug-ins can now be added to Chains.
  598. * New "Paulstretch" effect for extreme slowdown without pitch change.
  599. * New "Sample Data Export" Analyze effect for exporting a file
  600. containing amplitude values for each sample in the selection.
  601. * New Preference (off by default) to import files On-Demand (without
  602. seek ability) when using the optional FFmpeg library.
  603. * New Preference (off by default) to retain labels when deleting a
  604. selection that snaps to the label without extending past it.
  605. * (Windows installer) New option to reset Preferences on next launch.
  606. * (Mac) Audacity now has excellent compatibility with the VoiceOver
  607. screen reader. For details, please see:
  608. .
  609. * CleanSpeech Mode (no longer supported) will not now be enabled
  610. even if it was enabled by an earlier version of Audacity.
  611. * Added Serbian (Latin and Cyrillic) translations.
  612. Changes between version 1.3.14 Beta and 2.0.0:
  613. Bug fixes for:
  614. * Interface:
  615. * Fixed playback speed and synchronization problems when dragging
  616. clips or tracks between tracks having different sample rates.
  617. * (Windows) Removed a crash risk where shortcuts could be
  618. used to record or import in one project while importing or
  619. exporting in another.
  620. * Imports and Exports:
  621. * Fixed crashes when changing the sample format of read-directly WAV
  622. or AIFF files using the Track Drop-Down Menu.
  623. * Fixed a crash importing MP3 files that had duplicate metadata tags
  624. (this is a bug in current libsndfile which has been patched in
  625. Audacity; MP3 files mislabeled as WAV which have duplicate tags
  626. will still crash Audacity on Linux if Audacity has been compiled
  627. against an affected version of system libsndfile).
  628. * Fixed an issue where excessively high or corrupted sample values in
  629. the audio could corrupt exports from the start of the problem for
  630. the rest of the file, and could corrupt the rest of the project.
  631. * (Linux) Fixed Audacity could not be compiled against FFmpeg
  632. 0.7.x and 0.8.x.
  633. * Effects and Analysis:
  634. * Fixed crash on launch when using "Ambisonic Decoders (PC)" VST
  635. plug-ins and other plug-ins that enable additional floating point
  636. exceptions.
  637. * Fixed Plot Spectrum background could be transparent on some machines.
  638. * Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
  639. * Chirp, Tone and Silence generators now remember their settings.
  640. * Other miscellaneous bug fixes.
  641. Changes and Improvements:
  642. * New Interface preference to show the track name in the display (this
  643. is off by default).
  644. * Longer default Playback preference for effects preview and preview
  645. before cut.
  646. * Restored use of Page Up and Page Down to scroll horizontally.
  647. Summary of bug fixes and new features between 1.2.6 and 2.0.0:
  648. * Bug Fixes:
  649. * Labels now accept lower case "z".
  650. * (Windows Vista/7) Pressing Stop after recording could cause a crash.
  651. * (Mac OS X) Fixed shortcut keys activating when typing in file open or
  652. save windows.
  653. * (Mac OS X) Audacity 2.0.0 fully supports Unicode, which fixes an
  654. issue where Audacity could not work with folders having non-English
  655. characters in their name.
  656. * (Linux) Playing existing tracks while recording in mono could cause
  657. recordings to be distorted or low-pitched.
  658. * New features: There are dozens of new features in 2.0.0, including:
  659. * Many effects significantly improved, especially Equalization, Noise
  660. Removal and Normalize. Vocal Remover now included plus GVerb on
  661. Windows and Mac. VAMP analysis plug-ins now supported.
  662. * Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu.
  663. Multiple clips per track. Tracks and selections can be fully
  664. manipulated using the keyboard. Many more keyboard shortcuts.
  665. * New Device Toolbar to manage inputs and outputs. Timer Record feature.
  666. New Mixer Board view with per-track VU meters.
  667. * Automatic Crash Recovery in the event of abnormal program termination.
  668. * Fast "On-Demand" import of WAV/AIFF files if read directly from source.
  669. FLAC now fully supported. Added support for optional FFmpeg library
  670. for import/export of AC3/M4A/WMA and import of audio from video files.
  671. Please visit for a full
  672. list of features in 2.0.0. You can click Help > Manual (in web browser)
  673. in the program to read more.
  674. Changes in version 1.3.14 Beta:
  675. Bug fixes for:
  676. * Interface:
  677. * Excessive delay occurred when typing into labels in long projects.
  678. * Last digit of TimeText controls could not be manipulated in some formats.
  679. * (Windows, OS X) Play and Record shortcuts did not work after clicking in
  680. Device Toolbar.
  681. * (OS X, Linux) Crash occurred if Toolbars were reset during playback or
  682. recording.
  683. * Imports and Exports:
  684. * MP2 files were not importable without FFmpeg library or an import rule.
  685. * Files that could only be imported using FFmpeg imported as noise with
  686. no error message if FFmpeg was not available.
  687. * Files containing PCM audio but an incorrect extension (such as MP3)
  688. caused a freeze.
  689. * Effects and Analysis:
  690. * An empty command could be added to a Chain which then displayed a
  691. Nyquist error message when run.
  692. * Plot Spectrum didn't preserve signal level if multiple tracks were
  693. analyzed.
  694. * Other bug fixes:
  695. * Audacity has been provisionally fixed so that it can no longer create
  696. block files longer than the sample format or project format allows,
  697. and can no longer delete these, which led to data loss. Any overlong
  698. blocks found are preserved but "orphaned", so will appear as silence.
  699. * Orphan block files were wrongly reported if cutting or copying to
  700. the clipboard then reopening the project in the same session.
  701. * Fixed some crashes and incorrect movement of audio when dragging tracks.
  702. * (Windows) Data loss is now prevented when encountering a corrupted
  703. .aup file created in ANSI builds.
  704. * (Linux) Restore building if USE_PORTMIXER is not defined.
  705. Changes and Improvements:
  706. * Normalize: Faster processing and improved interface. Left-right balance
  707. in unsplit stereo tracks is now preserved by default, with a checkbox
  708. option provided to process stereo channels independently.
  709. * Spectrograms now allow window sizes up to 32768 and frequencies up to
  710. half the sample rate (the maximum possible).
  711. * Mix and Render now preserves clip length by not rendering white space
  712. between time zero and first audio, and preserves audio before time zero.
  713. To retain silence before the audio starts, generate silence after render.
  714. * Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
  715. * CleanSpeech Mode removed from Interface Preferences (it still runs if it
  716. was enabled in a previous Audacity but can only be turned off there).
  717. * (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
  718. * (Linux) Set the per-user files directory per the program name set in
  719. configure.
  720. * (Linux) Changed the default location of the Audacity temporary directory
  721. to be in /var/tmp not /tmp, so preserving the directory between reboots.
  722. Changes in version 1.3.13 Beta:
  723. Bug fixes for:
  724. * Interface:
  725. * Cutting or copying from a track at a given sample rate into a track
  726. at another rate resulted in speed-changed audio.
  727. * Generating inside a clip could modify the clip length or create
  728. spurious clips.
  729. * Recorded stereo tracks were only half the height of imported or
  730. generated stereo tracks. Imported stereo files had a "1" appended
  731. to the track name.
  732. * Edit > Region Save did not save the cursor position.
  733. * (Windows) Projects crashed when clicking rapidly inside the interface
  734. or when applying repeated effects towards the end of audio tracks.
  735. * (Windows) Some Unicode characters could not be typed into labels,
  736. or caused a freeze using some input methods.
  737. * (OS X) Crash when quitting an empty project window, or when closing the
  738. main project window while a progress dialog was on screen.
  739. * Numerous other interface fixes including Dependencies dialog,
  740. Keyboard Preferences and spurious lines drawn on waveform.
  741. * Imports and Exports:
  742. * Support added for later versions of the optional FFmpeg library up to
  743. current FFmpeg HEAD. This should significantly improve FFmpeg support
  744. on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This
  745. fixes mono AAC files importing as stereo, though current 0.5 versions
  746. of FFmpeg will still work.
  747. * Both FFmpeg and LAME should now be properly detected even when other
  748. versions of those libraries exist on the system.
  749. * New warning (on by default) for importing uncompressed audio files.
  750. Better error messages when read-directly uncompressed files are missing.
  751. * Imported ID3v2 metadata tags were removed when exporting without the
  752. Metadata Editor appearing (for example, when using an export command
  753. in Chains). Note: As a result of this fix, ID3v1 tags must now be
  754. written by exporting using (external program) and an installed LAME.
  755. * U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk,
  756. so should now be recognised by most telephony applications.
  757. * Variable bit rate MP3s exported using "MP3 Files" were larger than
  758. necessary because using the bit reservoir was disabled.
  759. * (OS X) Files imported from iTunes could create invalid characters in the
  760. .aup project file, causing an error when re-opening the project. Note:
  761. An error "reference to invalid character number" will still occur if
  762. re-opening a project created in previous Betas that contains such
  763. characters. To fix the issue, open a back-up copy of the .aup file in a
  764. text editor, turn off word wrap, then in the line indicated in the error
  765. message, remove the string of characters that starts with &# and ends
  766. with a semi-colon (;).
  767. * Other bug fixes:
  768. * Nyquist effects: fixes for crashes, incorrect slider behaviour and better
  769. support for backslashes, double quotes and Unicode characters.
  770. * (Windows and OS X) Processing of VST effects was substantially slower than
  771. in previous versions of Audacity.
  772. * (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang
  773. on launch if VST effects were detected.
  774. * (Linux) Recordings made with the pulse device crashed or stalled when
  775. using overdub and/or software playthrough.
  776. * (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was
  777. configured with libsamplerate.
  778. Changes and Improvements:
  779. * Control Toolbar renamed to Transport Toolbar.
  780. * Device Toolbar (on by default) now contains all input and output device
  781. choices, including host and recording channels. Input/output choices are
  782. no longer in Mixer Toolbar on Windows XP or some older operating systems.
  783. New Transport > Rescan Audio Devices menu item to refresh the device list.
  784. * New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow
  785. groups of audio and/or label tracks to retain synchronisation when the
  786. track length changes.
  787. * Equalization: New "Manage Curves" dialog for importing and exporting curves.
  788. * Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and
  789. new option to isolate noise.
  790. * New "Extended Import" Preferences for specifying different importers to
  791. open specific file extensions.
  792. * Improved Automatic Crash Recovery with all project changes autosaved.
  793. * MIDI tracks can be vertically zoomed, time shifted and display bar lines.
  794. Note: the channel selection buttons are not available in 1.3.13.
  795. * (Windows and Linux) The window Close button and other system close or
  796. shutdown commands now quit on closing the last window. File > Close now
  797. always clears to a new, empty project.
  798. * (OS X) Simpler installer with top-level "Audacity" folder.
  799. Changes in version 1.3.12 Beta:
  800. Bug fixes for:
  801. * Imports and Exports:
  802. * AAC files could not be exported at 48000 Hz
  803. * When importing multiple native file formats using FFmpeg, all
  804. files after the first reverted to using the native importer
  805. * FFmpeg custom export window too large on 800 x 600 resolution
  806. monitors
  807. * Projects froze if files imported via On-Demand were no longer
  808. available
  809. * (Linux) WAV/AIFF exports were corrupted if overwriting an aliased
  810. file which had been imported using the command line
  811. * Labels:
  812. * Cutting or deleting a region in the waveform and label track did
  813. not move the labels in advance of the cut
  814. * Incorrect behavior snapping to labels and boundaries when Snep To
  815. was enabled
  816. * Labels can now be reversed if included with the audio selection
  817. * Other bug fixes:
  818. * When using non-English languages, Generate effects truncated the
  819. selected region
  820. * Mice with high-precision scroll-wheels could cause a crash
  821. * Changing recording preferences using the Transport menu did
  822. not update the menu in other open projects
  823. * (Windows 7) Clicking in a file open or save dialog caused files or
  824. folders to disappear from the list, and file filtering was broken
  825. Changes and improvements:
  826. * A hover tooltip is now provided if the Mixer Toolbar input selector
  827. cannot control the system slider for the selected input.
  828. * More intuitive behavior when moving and resizing labels by dragging
  829. * Support added for importing lists of files (LOF) containing relative
  830. paths
  831. * Export Multiple: new option to use a numerical prefix before existing
  832. label or track names; "Success" dialog now resizable
  833. * New Equalization preset "Inverse RIAA", with new button to invert
  834. other curves
  835. * Timer Record now remembers last scheduled duration
  836. * Meter Toolbar can now be made much narrower, and so more suitable for
  837. vertical orientation
  838. * New Preferences choice for "System" language which is used on first
  839. run instead of asking user to choose language
  840. * Warning now provided if WAV/AIFF exports are not successfully
  841. completed
  842. * (Linux) Improved icon set in compliance with
  843. Icon Theme Specification 0.6
  844. Changes in version 1.3.11 Beta:
  845. Bug fixes for:
  846. * Imports and Exports:
  847. * Bug when exporting partial selections caused too much audio to be
  848. exported is fixed.
  849. * Fix corrupt files exported through FFmpeg when metadata included,
  850. (metadata is now exported correctly in M4A files)
  851. * Prevent saving a new Audacity Project over an existing one as this
  852. could corrupt both projects.
  853. * Improved help for files that cannot be imported because the relevant
  854. optional library is missing.
  855. * Effects:
  856. * Allow effects which change the length of the audio they work on to also be
  857. applied to selected label tracks, thus keeping them synchronized.
  858. * Fixed inability in Nyquist plug-ins to add labels to an existing label track
  859. * (Mac) Equalization window was corrupted after Preview
  860. * (Linux 64-bit) Fixed crash Generating Click Track
  861. * Audio Devices:
  862. * Fixed bug causing recording to stop short when the recording sample rate

  1385. Changes in 1.3.0:
  1386. New features
  1387. The new features in Audacity 1.3 have been grouped into the
  1388. following six major categories.
  1389. 1. Collapse/Expand Tracks
  1390. In Audacity 1.3, every track has an upward-pointing triangle at
  1391. the bottom of the label area on the left side of the track.
  1392. 2. Multiple clips per track
  1393. In Audacity 1.2, there is one audio 'clip' per track. There is
  1394. no easy way to time-shift part of a track without moving the
  1395. rest. In Audacity 1.3, you can split a single track into multiple
  1396. clips. You can move these clips around between different tracks,
  1397. making it easy to construct complex compositions out of hundreds
  1398. of smaller audio samples.
  1399. 3. Selection Bar
  1400. In Audacity 1.2, the current selection is contained in a
  1401. status bar at the bottom of the window. In Audacity 1.3,
  1402. this is replaced by a fully functional Selection Bar, which
  1403. displays and controls the current selection (your choice of
  1404. Start and End, or Start and Length), and the current audio
  1405. position. The selection bar is fully editable - just click
  1406. in any field and type to change the current selection precisely.
  1407. In addition, many formatting options allow you to view times in
  1408. different units, such as samples, CD frames, or NTSC video frames.
  1409. 4. Improved Label Tracks
  1410. Label Tracks are Audacity's way for you to create markings 3
  1411. and annotations within your project. In Audacity 1.3, Label
  1412. Tracks are much improved, with support for overlapping labels,
  1413. and support for modifying both the left and right edge of the
  1414. label region just by clicking and dragging.
  1415. 5. QuickTime and Audio Units on Mac OS X
  1416. On Mac OS X, Audacity can now import and audio file supported
  1417. by Apple's QuickTime technology. This includes .MOV and .MP4
  1418. (AAC) files. Unfortunately encrypted audio files (such as
  1419. those from the iTunes Music Store) cannot be imported directly
  1420. into Audacity - Apple does not allow this to be done easily
  1421. because it would be too easy to circumvent the encryption this way.
  1422. Also on Mac OS X, Audacity now supports Audio Unit plug-ins.
  1423. Audacity searches for Audio Units in the usual location, in the
  1424. system or user's Library folder.
  1425. 6. Other features
  1426. Better performance with large projects
  1427. Project integrity check on open
  1428. Transcription toolbar
  1429. Upload
  1430. Batch
  1431. Cut lines
  1432. CleanSpeech
  1433. Changes in 1.2.4:
  1434. * The File menu now includes a list of recent files.
  1435. * The "Generate Silence" effect now prompts for a length.
  1436. * Audacity is now built with Vorbis 1.1, which features better encoding
  1437. quality and file compression.
  1438. * Dragging sound files into the Audacity window now works on Mac OS X
  1439. and Linux, as well as Windows. (Before, it worked only on Windows.)
  1440. * The "View History" window can now discard old undo levels to save disk
  1441. space on Windows. (This previously worked only on Linux and Mac.)
  1442. * "Preferences" command is now in Edit menu.
  1443. * "Plot Spectrum" command is now in Analyze menu.
  1444. * Opening a project file saved by a later version of Audacity displays
  1445. an intelligent error message. Also, trying to import a project file
  1446. (instead of open it) displays an intelligent error message.
  1447. * Audacity now compiles in Visual C++ .NET 2003.
  1448. * Other minor bug fixes.
  1449. * New or updated translations: Arabic (ar), Czech (cs), Finnish (fi),
  1450. Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl),
  1451. Simplified Chinese (zh_CN), Traditional Chinese (zh_TW).
  1452. Changes in 1.2.3:
  1453. * Fixed a bug that caused recording to stop or display incorrectly
  1454. after about 50 minutes on some Windows systems. (This was partly
  1455. fixed in Audacity 1.2.2, but still didn't work on some systems.)
  1456. * The Change Pitch and Change Tempo effects have been upgraded to
  1457. use a new version of the SoundTouch library by Olli Parviainen,
  1458. with better speed and higher quality.
  1459. * libsndfile has been upgraded to version 1.0.11.
  1460. * Fixed a bug that caused the program to run slowly when using the
  1461. Envelope tool.
  1462. * Shift-clicking on a mute or solo button now un-mutes (or un-solos)
  1463. all other tracks.
  1464. * Nyquist plug-ins can now accept strings as input. Also, a "Debug"
  1465. button has been added to Nyquist effect dialogs, which allows you
  1466. to see all of the output produced by Nyquist, for aid in debugging.
  1467. * When the audio file referenced ("aliased") by an Audacity project is
  1468. missing, Audacity will now always play silence. Before, Audacity
  1469. would sometimes repeat the most recent audio that was played previously.
  1470. * VU Meters will now always reset when audio I/O has stopped.
  1471. * Fixed a major Mac-only bug that was causing Audacity to crash at seemingly
  1472. random times, but especially during audio playback and recording.
  1473. * New or updated translations: Italian (it), Hungarian (hu),
  1474. Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh),
  1475. Norsk-Bokmal (nb), French (fr).
  1476. Changes in 1.2.2:
  1477. * VU Meters added for both playback and recording. Click on
  1478. the recording meter to monitor the input without recording.
  1479. * Export Multiple - new feature that lets you export multiple
  1480. files at once, either by track, or split based on labels.
  1481. * Attempt to automatically correct latency in full-duplex recordings.
  1482. (This does not work perfectly, and is not yet supported on all
  1483. systems. It will improve in future versions.)
  1484. * Fixed a serious bug that could cause data loss when you save and
  1485. then reload and re-edit an Audacity project containing repeated
  1486. or duplicate data.
  1487. * MP3 tags dialog will only pop up the first time you export as
  1488. MP3; after that it will not pop up again as long as you have
  1489. filled in at least one tag.
  1490. * You can now add a label at the current playback position - in
  1491. the Project menu, with a shortcut of Ctrl+M.
  1492. * Clicking on a label now selects all of the tracks, making it
  1493. easier to use the label track to recall selections.
  1494. * Windows: Fixed a crash in the Time Track "Set Rate" command.
  1495. * Fixed a bug that caused problems with recordings over 45 minutes
  1496. on some Windows systems.
  1497. * Mac OS X: Improved support for the Griffin iMic by fixing a bug
  1498. that was causing it to always record in mono instead of stereo.
  1499. * Added support for Software Playthrough (listen to what you're
  1500. recording while recording it, or while monitoring using a VU
  1501. meter) - this makes it possible, for example, to record using one
  1502. audio device while listening to it play through a separate device.
  1503. * Unix/Linux: Fixed freeze caused by captured mouse when audio
  1504. device hangs. (Audacity may not respond, but it will no longer
  1505. freeze all of X.)
  1506. * Fixed a cosmetic bug that caused improper waveform display if
  1507. you tried to open an Audacity project saved on a different
  1508. platform (e.g., copying a project from a Mac to a PC).
  1509. * Fixed bug that could cause instability when pasting, splitting,
  1510. or duplicating a label track.
  1511. * You can now change the font of a label track by choosing "Font..."
  1512. from the label track's pop-up menu.
  1513. * Basic printing support has been added. Currently it scales the
  1514. entire project to fit exactly on one page. Try printing in
  1515. landscape orientation for best results.
  1516. * Mac OS X and Windows: Audacity ships with a newer version (1.0.1)
  1517. of the Ogg Vorbis encoder. Vorbis compression will now have higher
  1518. quality and smaller file sizes.
  1519. * Fix a bug that occasionally caused crashes when applying effects
  1520. to split tracks.
  1521. * Zoom In / Zoom Out now properly disable when they're not available.
  1522. * Fixed disk memory leak in Preview
  1523. * Other minor bug fixes and performance improvements.
  1524. Changes in 1.2.1:
  1525. * The following translations have been added or updated: Finnish,
  1526. French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.
  1527. * Fix a bug that could cause data to be lost when pasting audio
  1528. from one project into another, after the first project has been
  1529. saved and closed.
  1530. * Fix a possible crash when opening or resizing the Equalization
  1531. window, especially when using large system fonts.
  1532. * Don't allow percentages less than -100% in Change Pitch/Speed/Tempo
  1533. effects (fixes a possible crash).
  1534. * Fix a crash when the temporary directory is not available on startup.
  1535. * Correctly load ID3 tags saved in Audacity project files.
  1536. * On Linux and OS X, store lockfiles in the temp directory instead of
  1537. the user's home directory. This fixes problems in lab environments
  1538. where users have restricted or network-mounted home directories.
  1539. * Fix a bug that prevented Nyquist effects from running when certain
  1540. regional settings were activated.
  1541. * Fix a bug in the Quick Mix command that could cause old temporary
  1542. files to not be deleted.
  1543. * Linux: Fix endianness problems in playback on PowerPC.
  1544. * Linux: Fix compilation problem in Nyquist on MIPS.
  1545. * Linux: Include a more recent PortAudio v19 snapshot (fixes compilation
  1546. problems when building with the --with-portaudio=v19 option).
  1547. * Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."
  1548. * Other minor bug-fixes.
  1549. Changes in 1.2.0:
  1550. * New cross-fade effects.
  1551. * Fix problem where samples were drawn in the wrong position
  1552. when zoomed all the way in. This caused the drawing tool
  1553. to move a different sample than the one under the cursor.
  1554. * Don't use id3v2.4 tags, which are not yet supported by
  1555. most players. (This was fixed in 1.2.0-pre2, but appeared
  1556. again by accident in 1.2.0-pre3.)
  1557. * Correctly display translated messages in the status bar.
  1558. * When the cursor is on-screen, the Zoom In button now zooms
  1559. to the area around the cursor.
  1560. * Mac OS X: Fixed audio problems on the Apple PowerMac G5.
  1561. * Linux/ALSA: Work around a bug in ALSA's OSS emulation that
  1562. caused Audacity's playback cursor to move too quickly.
  1563. * Microsoft Windows: The Audacity source code should now
  1564. compile out of the box on Windows.
  1565. * Many new/updated translations.
  1566. Changes in 1.2.0-pre4:
  1567. * Fixed problems that could occur when importing certain
  1568. non-seekable PCM audio files, such as GSM610.
  1569. * Fixed bug that was causing the samples to shift off-screen
  1570. horizontally when zoomed in very far and the track had a
  1571. time-shift offset.
  1572. * Fixed bugs in the new resampler that added noise to resampled
  1573. audio on some systems. If you experienced noise when exporting
  1574. to a WAV, MP3 or OGG file you may have been bitten by this bug.
  1575. * Fixed bug that led to occasional crashes when using the
  1576. time-shift tool in conjunction with high zoom factors.
  1577. * Dithering is now only applied on export when it is really
  1578. necessary (e.g. when converting float samples to 16-bit).
  1579. * Files that only contain mono tracks are now automatically
  1580. exported to stereo files when they contain tracks which are
  1581. panned to the left or the right.
  1582. * The Delete key can now be used to delete the current selection,
  1583. in addition to the Backspace key.
  1584. * Fixed bug where Audacity didn't ask whether to save
  1585. changes if you close the project or exit while recording.
  1586. * Mac OS X: Supports Playthrough (listen to what you're recording
  1587. while recording it) if your hardware device supports it.
  1588. * Mac OS X: Audacity is now a package (you can right-click on
  1589. and select 'Show Package Contents'). Launch time
  1590. has improved significantly.
  1591. * MS Windows: Fixed problem that caused Windows XP to use
  1592. the short name of a file ("TESTFI~1.AUP"), which led to
  1593. problems when the file was later opened again using the
  1594. long file name.
  1595. * MS Windows: Fixed bug that caused file exports to fail
  1596. if the destination directory was the root folder of a
  1597. Windows drive.
  1598. * MS Windows: Audacity's application information which
  1599. is written to the Windows registry now always contains
  1600. the full path to the executable.
  1601. * MS Windows: Fixed problems in trying to set the Windows
  1602. registry as non-admin user, for file-type associations.
  1603. * Make sure the "Save" command is enabled after changing
  1604. gain and pan sliders.
  1605. * Updated translations. Added translator credits to the
  1606. "About" window in localized versions.
  1607. Changes in 1.2.0-pre3:
  1608. * Fixed bug where Export is grayed out when nothing is
  1609. selected.
  1610. * Fixed crash caused by opening Audacity on a computer with
  1611. a high-end sound card with no mixer support.
  1612. * Fixed crash in Import Raw.
  1613. * Fixed New Stereo Track.
  1614. * Cosmetic fixes for Mac OS X.
  1615. * Support for the VST Enabler on Windows added.
  1616. * Fixed crash if you close Audacity while the Preferences
  1617. dialog is open.
  1618. * Fixed duplicate-character bug in Mac OS X Label Tracks.
  1619. * The recording level control on Linux now adjusts the IGAIN,
  1620. rather than the playthrough level of the recording source.
  1621. * Fixed bug that caused corruption to 16-bit stereo recordings.
  1622. * Fixed bug that caused data loss if you deleted all tracks in
  1623. a saved project and then open a new file into the same window.
  1624. * Added support for alternate audio button order (in Interface
  1625. preferences)
  1626. * Added preliminary support for wxX11
  1627. * Added fully transparent Windows XP icon
  1628. * Fixed crash if you try to record (or play) and no audio
  1629. devices exist, or if the audio device doesn't support the
  1630. mode you selected.
  1631. * Audacity no longer sets the process priority to high while
  1632. recording on Windows. Users can still do this manually
  1633. using the Task Manager.
  1634. * Fixed bug that caused last ~100 ms of the selection to get
  1635. cut off on Windows.
  1636. * Fixed FFT Filter and Equalization effects dialogs.
  1637. * Fixed bugs in Unix build system (DESTDIR in locale directory,
  1638. choosing libsamplerate instead of libresample)
  1639. * Support for LADSPA plug-ins on Windows added, and
  1640. three open source LADSPA plug-ins ported to Windows
  1641. (GVerb reverb, SC4 compressor, and Hard Limiter)
  1642. Changes in 1.2.0-pre2:
  1643. * Online help completed. The full manual is nearly complete
  1644. and will be posted to the web site for online browsing shortly.
  1645. * Audacity will no longer let you do unsafe editing operations
  1646. while playing or recording. This eliminates many potential
  1647. crashes.
  1648. * Fixed ability to cancel Quit button.
  1649. * New resampling library, with no restrictions on the maximum or
  1650. minimum rate of resampling.
  1651. * Audacity now supports LADSPA plug-ins on all platforms, and
  1652. supports VST plug-ins through an optional LADSPA plug-in
  1653. called the "VST Enabler", which you can download separately.
  1654. Because of licensing issues, Audacity cannot be distributed
  1655. with VST support built-in.
  1656. * Mac OS X keyboard shortcut problems have been fixed.
  1657. * Mac OS X audio muting problems have been fixed.
  1658. * Mac OS X playback/recording cursor sync problems have been fixed.
  1659. * Silence now displays a straight line again, instead of nothing.
  1660. * Added a vertical ruler to the Waveform dB display.
  1661. * Fixed crash in Change Pitch.
  1662. * You can now Paste if nothing is selected.
  1663. * Canceling an Import operation doesn't cause an extra error
  1664. dialog to appear.
  1665. * Audacity now handles filenames with international characters
  1666. correctly.
  1667. * Now outputs ID3v2.3 tags (instead of ID3v2.4), to be
  1668. compatible with more MP3 players.
  1669. * Minor improvements to build system on Unix systems.
  1670. New features in Audacity 1.2:

  1679. - Amplify using envelope.
  1680. - Labels can store selections (like Audacity 1.0.0).
  1681. * Effects
  1682. - Repeat Last Effect command
  1683. - Improved VST plug-in support
  1684. - Most effects now have a Preview button
  1685. - Compressor (Dynamic Range Compressor)
  1686. - Change Pitch (without changing tempo)
  1687. - Change Tempo (without changing pitch)
  1688. - Change Speed (changing both pitch and tempo)
  1689. - Repeat (useful for creating loops)
  1690. - Normalize (adjust volume and DC bias)
  1691. * Audio I/O

  1713. - New Mixer toolbar allows you to control the output
  1714. volume, input volume, and input source directly
  1715. from Audacity.
  1716. - Every track now has its own gain and pan controls.
  1717. * File I/O
  1718. - Uses improved project file format. (Unfortunately reading
  1719. previous formats, including 1.1.1, is not supported.)
  1720. - Block files (stored in Audacity project directories) now
  1721. use the standard AU format. Though some Audacity
  1722. meta-information is in these files, they can now be
  1723. read by many other popular audio programs as well.
  1724. - Fixed some bugs relating to reading/writing audio
  1725. files with more than 16 bits per sample.
  1726. - Import RAW is functional again, with a simpler GUI
