Audacity v 2.1.2
Jan 26, 2016
MacOS X UB
Improvements
Effects
Noise Reduction defaults changed.
Interface
We’ve made several improvements to the spectrogram view of tracks which are particularly valuable for vocal work.
New option ‘Spectral Reassignment’. This algorithm deduces a ‘finer’ spectrogram for vocal work.
Four new Spectrogram scales.
Improvement to the Pitch (EAC) algorithm – cleaner (sharper) display.
Spectrogram Settings are now available per-track.
Other Changes
Upgraded from wxWidgets 2.8.12 to wxWidgets 3.0.2.
Restructuring of the Preferences Menu
Restructuring of the Track Dropdown Menu (for the Spectrograms)
The Noise Reduction "Frequency smoothing" default has been increased to 3 to help avoid metallic artifacts. Resetting Preferences or deleting audacity.cfg will set the new default.
(Windows) The location of Audacity's work-in-progress folder has been changed, to avoid problems where certain disk cleaners treated them as deletable temporary files.
Bug Fixes
Crashes
Crashes on reading .wav files with many channels (CVE-2016-2540) and corrupt .mp2 files (CVE-2016-2541) have been fixed. Thanks to Chris Navarrete from Fortinet’s FortiGuard Labs for notifying us of these bugs and associated security risk.

Classic Filters now included as an opt-in effect.
Interface
Much faster editing with larger projects, thanks to a faster method for storing the autosave recovery file.
Performance improvements for Draw Tool and zooming of Spectrogram views.
Zero-padding Spectrograms Preference smooths the image for short window sizes.
Scrubbing and Seeking, including backwards play.
Quick-Play from Timeline enhancements, particularly for looping.

Crash using File > Close on project window when Screenshot Tools was open.
FFmpeg Custom Export: Crashes importing presets.
(OS X) Crash closing Track Gain or Pan adjustment box.
(OS X) Crash closing project window between save project dialogues
(Linux) TAL VST (but not other VST's) crashed if previewing built-in effect
(Linux) SPACE could not be used/could crash in context menus that have a checkbox.
Interface
LV2 effects did not use parameters when using Chains.
Built in Generators were not usable in Chains.
Plot Spectrum could not change values without losing focus.
Track dropdown menu settings could affect other tracks.
Slight mismatch of vertical scale with linear spectrogram view.
RTP effect Play/Stop button remained deactivated after built-in preview ended.
Contrast: "Move forward or backward through active windows" did not refocus Contrast.
LADSPA and LV2 generate plug-ins failed when white space selected.
Mac OS X
Confusing behaviour importing / exporting AU presets. In particular, Apple Audio Units silently applied an imported preset.
Audacity v 2.1.0
Jul 21, 2015
MacOS X UB
Changes and Improvements:
* Effects:
* LADSPA, VST and Audio Unit (OS X) effects now support real-time preview,
save/load of user presets and saving effect settings across sessions.
Note: Real-time preview does not yet support latency compensation.
* VST effects now support import/export of FXB preset banks.
* Shell VST effects that host multiple plugins are now supported.
* All Effect Menu items (built-in or plugin) can now be used in a Chain.
* Items in the Effect, Generate or Analyze Menus can be sorted or grouped
by name, publisher or class of effect.
* Noise Removal is improved and renamed to "Noise Reduction".
* Change Speed has new time controls for current and new length. You can
now enter the speed change as a multiplier e.g. "2" is twice as fast.
* New "Crossfade Tracks" effect can be used for crossfading two tracks.
This replaces Cross Fade In and Cross Fade Out.
* Nyquist Prompt and most shipped Nyquist effects now have Preview button.
* Interface:
* Redesigned Meter Toolbars: The default shows separate Record and Playback
Meters, half-height so they can be wider while docked, in gradient style.
* A frequency selection can now be made (and spectral edit effects applied
to those frequencies) when in a spectrogram view. You can also create
or adjust frequency selections in a new "Spectral Selection Toolbar"
(available at View > Toolbars).
* Transcription Toolbar (Play-at-speed) can now loop play and cut-preview.
* Timer Record now saves recordings automatically into an existing project.
* New Armenian translation.
* Operating system and sound device support:
* (Windows) Audacity 2.1.0 requires Windows XP SP3 (32-bit) or XP SP2
(64-bit), Vista, Windows 7, Windows 8 or 8.1.
* (Windows) Audacity is now compiled using Visual Studio 2013.
* (Windows) Recording with WASAPI host now includes experimental support
for physical inputs (up to 24-bit depth) as well as loopback recording.
* (OS X) 10.10 (Yosemite) is now supported including Apple Audio Units.
* Please report any issues with WASAPI recording/playback or Yosemite
to http://audacity.sourceforge.net/contact/#feedback .
* (Linux Ubuntu) Under Unity, keyboard shortcuts are not visible in the
Audacity menus. Keyboard shortcuts are visible if you install the classic
GNOME Flashback interface or under Unity if you open Audacity with the
UBUNTU_MENUPROXY=0 environment variable. Audacity compiled from source
will ship with src/audacity.desktop.in set to UBUNTU_MENUPROXY=0 but it
will remain up to distributions to use this desktop file.
Bug fixes:
* Interface:
* Typing "j" or "k" in a label track activated the "move cursor" shortcut.
* Spectrogram log (f) view displayed incorrectly until vertically zoomed.
* Fixed crash after zooming out on vertical scale beyond +/-1.0.
* Selections made with Selection Toolbar were not restored after Undo.
* Undo could fail silently if a selection included/touched a clip boundary.
* Imports and Exports
* If there were invalid FFmpeg libs in system PATH this prevented Audacity
recognising the installed FFmpeg or the FFmpeg specified in audacity.cfg.
* Mac OS X:
* Fix uninitialized buffer - this should correct playback buzz or crackle
where the upper of multiple tracks started with or contained white space.
* Device names were corrupted when using system language other than English.
* Fixed crashes using (external program).
* Waves v9 Audio Units should now work correctly.
* GNU/Linux:
* Fix "Audacity already running" error when using the command-line or
context menu to open multiple or further files.
* Fix segfault exporting an FFmpeg format to an unwritable folder.
* Fix silent failure exporting FFmpeg, MP2 or OGG to an unwritable folder.
* Fix ENTER activated an effect when OK button was greyed out.
* Addendum:
* The previous Audacity 2.0.6 version fixed an issue that projects did not
reopen correctly if they contained tracks having 2^31 samples or greater
of audio (just over 13.5 hours at 44100 Hz).
Audacity v 2.0.6
Oct 4, 2014
MacOS X UB
Improvements:
better user interface for Keyboard Preferences
streamlining of several Menus
LV2 now supported on all platforms, and improved VST settings interface
translations updated, including adding Tamil language
other improvements, including to import/export and ease of installation on Mac OS X
Bug Fixes:
user interface bug fixes to Region Restore, dragging selections, and many others
effects bug fixes to add missing effects to Chains, fix accuracy of Analyze > Contrast, fix accuracy of Noise Removal attack and decay, and improve speed of Nyquist effects on OS X and Linux
other bug fixes to Timeline after Loop Play, Transcription Toolbar, and Linux build issues
Audacity v 2.0.5
Oct 22, 2013
MacOS X UB
Bug fixes
Shaped dither was corrupted and too loud on all stereo exports except FLAC.
Keyboard Preferences: some Edit and Align commands for different sub-menus showed the same name.
Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
In locales that use comma for decimal separator:
Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem.
Built-in generators produced silence after running a Nyquist effect.
(Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
(Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
(OS X) Frequent crashes occurred on importing audio files on some machines.
(OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon.
(Linux 64-bit) Fixed a crash when using Equalization.
(Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB.
(Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared.
Changes and Improvements
Tracks Menu:
The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands.
"Align and Move Cursor" renamed to "Move Selection when Aligning".
Label Tracks:
Labels Editor now allows empty labels to be saved on closing the editor.
TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label.
(Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
(Windows and OS X) Screen reader improvements for Install VST Effects dialog.
(OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units.
(Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
(Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
Audacity v 2.0.4
Sep 9, 2013
MacOS X UB
Bug fixes
Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it.
Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates.
Bass Boost no longer clips if the track contains 32-bit audio.
Auto Duck was excessively slow on older machines.
(Windows) Exported MP3 comments tags were not seen by Windows programs.
(Windows and OS X) Audacity crashed if you used system quit before file import was complete.
(Linux) Equalization crashed Audacity if the XML file was corrupted.
(Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash.
(Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
Numerous other interface fixes.
Changes and Improvements
New "Reverb" effect to replace GVerb, based on the original "Freeverb".
New View > Go to Selection Start and Go to Selection End commands.
New Tracks > Align End to End command to append existing tracks to each other.
Change Tempo now supports fractional BPM.
Plot Spectrum now supports FFT sizes up to 65536.
WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO tags and also support ID3 tags.
Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
(Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
(Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
(Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.
(Linux) CTRL + ALT can now be used to smooth samples in Draw Tool.
Modules Preferences replaced with a dialog on launch of Audacity enabling you to choose which modules to load.
Audacity v 2.0.2
Aug 24, 2012
MacOS X UB
A significant bug that caused clicks on split lines has been fixed, and there are improvements to several toolbars and to some Nyquist effects.
Audacity v 2.0.1
Jul 2, 2012
MacOS X UB
Bug fixes
Interface
Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
Finding zero crossings could cause the selection to expand into white space at either side of the clip.
Clips did not drag to another track if mouse was over a selection.
Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
Imports, Exports and Files
Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
(Mac) Fixed crashes importing MP3 files on PPC machines.
(Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).
Effects and Analysis
Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
Other miscellaneous bug fixes
including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen.
Changes and Improvements
Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
Nyquist Effect plug-ins can now be added to Chains.
New "Paulstretch" effect for extreme slowdown without pitch change.
New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.
New Preference (off by default) to import files On-Demand (without seek ability) when using the optional FFmpeg library.
New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.
(Windows installer) New option to reset Preferences on next launch.
(Mac) Audacity now has excellent compatibility with the VoiceOver screen reader. For details, please see http://manual.audacityteam.org/help/manual/man/accessibility.html#mac.
CleanSpeech Mode (no longer supported) will not now be enabled even if it was enabled by an earlier version of Audacity.
Added Serbian (Latin and Cyrillic) translations.
Audacity v 2.0.0
Mar 14, 2012
MacOS X UB
Bug fixes
Interface
Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
(Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.
Imports and Exports
Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
(Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.
Effects and Analysis
Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
Fixed Plot Spectrum background could be transparent on some machines.
Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
Chirp, Tone and Silence generators now remember their settings.
Other miscellaneous bug fixes
Changes and Improvements
New Interface preference to show the track name in the display (this is off by default).
Longer default Playback preference for effects preview and preview before cut.
Restored use of Page Up and Page Down to scroll horizontally.
Audacity v 1.3.14beta
Dec 13, 2011
MacOS X UB
Bug fixes for:
Interface:
Excessive delay occurred when typing into labels in long projects.
Last digit of TimeText controls could not be manipulated in some formats.
(Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar.
(OS X, Linux) Crash occurred if Toolbars were reset during playback or recording.
Imports and Exports:
MP2 files were not importable without FFmpeg library or an import rule.
Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.
Effects and Analysis:
An empty command could be added to a Chain which then displayed a Nyquist error message when run.
Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.
Other bug fixes:
Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence.
Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
Fixed some crashes and incorrect movement of audio when dragging tracks.
(Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
(Linux) Restore building if USE_PORTMIXER is not defined.
Changes and Improvements:
Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently.
Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).
(OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
(Linux) Set the per-user files directory per the program name set in configure.
(Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots.
Audacity v 1.3.13beta
Apr 12, 2011
MacOS X UB
Bug fixes for:
Interface:
* Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
* Generating inside a clip could modify the clip length or create spurious clips.
* Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name.
* Edit > Region Save did not save the cursor position.
* (Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks.
* (Windows) Some Unicode characters could not be typed into labels,or caused a freeze using some input methods.
* (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
* Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.
Imports and Exports:
* Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
* Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
* New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
* Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
* U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
* Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled.
* (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).
Other bug fixes:
* Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
* (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
* (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.
* (Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough.
* (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate.
Changes and improvements:
* Control Toolbar renamed to Transport Toolbar.
* Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
* New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
* Equalization: New "Manage Curves" dialog for importing and exporting curves.
* Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise.
* New "Extended Import" Preferences for specifying different importers to open specific file extensions.
* Improved Automatic Crash Recovery with all project changes autosaved.
* MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
* (Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project.
* (OS X) Simpler installer with top-level "Audacity" folder.

* FFmpeg custom export window too large on 800 x 600 resolution monitors
* Projects froze if files imported via On-Demand were no longer available
* (Linux) WAV/AIFF exports were corrupted if overwriting an aliased file which had been imported using the command line
Labels:
* Cutting or deleting a region in the waveform and label track did not move the labels in advance of the cut
* Incorrect behavior snapping to labels and boundaries with Snap To enabled
* Labels can now be reversed if included with the audio selection
using the command line
Other bug fixes:
* When using non-English languages, Generate effects truncated the selected region
* Mice with high-precision scroll-wheels could cause a crash
* Changing recording preferences using the Transport menu did not update the menu in other open projects
* (Windows 7) Clicking in a file open or save dialog caused files or folders to disappear from the list, and file filtering was broken
Changes and improvements:
* A hover tooltip is now provided if the Mixer Toolbar input selector cannot control the system slider for the selected input.
* More intuitive behavior when moving and resizing labels by dragging
* Support added for importing lists of files (LOF) containing relative paths

in progress dialogue and over-estimated "Remaining Time"
* Cancelling Nyquist effects deleted unprocessed audio

* File > Export as WAV could be corrupted if overwriting
an imported WAV read direct from the file

produced 16-bit PCM audio irrespective of chosen options.

irrespective of chosen options; reported length often
incorrect

Metadata Editor was opened and saved
