Audacity Changelog

New in version 2.0.5

October 22nd, 2013
  • Includes all the changes featured in the previous Beta versions

New in version 2.0.5 RC1 (October 16th, 2013)

  • 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.
  • When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
  • On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
  • 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.
  • 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.
  • Screen reader improvements for Install VST Effects dialog.

New in version 2.0.4 (September 7th, 2013)

  • 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.
  • 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.
  • Modules Preferences replaced with a dialog on launch of Audacity enabling you to choose which modules to load.

New in version 2.0.3 (January 22nd, 2013)

  • Bug fixes for:
  • Crash using Undo whilst time-shifting a track.
  • Crash using Repair if the selection extended into an empty track.
  • Export Multiple didn't prevent export if there was no audio or all audio was muted. This allowed export of small invalid files.
  • Time Track:
  • Loop Play of a speeded-up track inserted silence.
  • Playback and rendering was significantly inaccurate, creating
  • audible and visual glitches.
  • Accessibility:
  • The mnemonics character "&" was read out by screen readers in most of the Preferences choices.
  • NVDA did not read static text in most dialogs. Text can now be read by using INSERT + B.
  • JAWS and Window-eyes misread the "Duration" control in Silence Generator.
  • Toolbar buttons could not be pressed by ENTER
  • Other interface bug fixes.
  • Changes and Improvements:
  • The SoX Resampler library (libsoxr) has replaced libresample in
  • Audacity releases, offering both higher quality and greater speed. .
  • Time Tracks new features:
  • "Set Range" now changes only the range of the Time Track, preserving the pitch/speed set by any existing warp points.
  • Vertical scale added with options for linear and logarithmic display and interpolation.
  • Upper and lower speed limits will now be remembered when saving and reopening a project in 2.0.3. Warp points in projects saved by previous Audacity versions will be correctly restored in 2.0.3.
  • Warp points saved in a 2.0.3 project will be preserved if opened in previous versions but playback and display will be incorrect.
  • New effects:
  • Studio Fade Out (uses a filtered "S" curve).
  • Adjustable Fade (accessible effect for creating partial fades
  • and adjustable fade shapes).
  • Bass and Treble (replaces Bass Boost).
  • General:
  • Real sample rates up to 384000 Hz are now supported for playback and recording in high resolution devices (the maximum is up to 192000 Hz for Windows DirectSound host).
  • Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now allows splits to be placed at point labels. Labeled audio regions that touch without overlapping are treated as separate regions. Overlapping labeled audio regions are treated as a single region.
  • New Croatian translation of Audacity.
  • Compilation:
  • CMake is required in order to build libsoxr

New in version 2.0.2 (August 24th, 2012)

  • Bug fixes:
  • Interface:
  • "Retain labels" Interface Preference did not retain labels for a region that snapped exactly to both label edges.
  • Projects did not save the track selected state.
  • (Windows) JAWS screen-reader did not read the "Draw curves" and "Graphic EQ" radio buttons in Equalization correctly.
  • Envelopes and Clips:
  • Exporting (or any render operation) on a track containing split lines could create clicks at the split lines.
  • Effects and Analysis:
  • Normalize could crash if the track name contained "%".
  • Changes and Improvements:
  • Duration controls when generating at a point now default to hh:mm:ss + milliseconds format. Selection Toolbar also defaults to that format on first installation or resetting preferences.
  • Toolbars visual improvements:
  • "Snap To" in Selection Toolbar now has an explanatory tooltip
  • Device Toolbar tooltips now display the selected device
  • Increased default width of Device Toolbar and Meter Toolbar.
  • Improvements and some bug fixes to Nyquist effects, including:
  • Delay (new option to prevent duration change)
  • Sample Data Export (new "L-R on Same Line" layout option)
  • Risset Drum (new "Amplitude" slider).
  • Importing a labels file writes the file name to the name of the Label Track, and exporting a labels file offers the name of the last Label Track in the project.
  • Removed the "Audio cache" option from Directories Preferences due to frequent crash reports. All data operations will now be written to disk and not to RAM.
  • Removed the FFmpeg "On-Demand" option from Libraries Preferences (this fixes Audacity not building if configured --without-ffmpeg).
  • Compilation: Progress on making the Modules feature mainstream. Modules can now be individually enabled and disabled in Preferences.

New in version 2.0.1 (August 10th, 2012)

  • 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.
  • 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.
  • 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.

New in version 2.0.0 RC2 (February 20th, 2012)

  • Bug fixes since 1.3.14 Beta:
  • Interface: (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:
  • Fix 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.

  • 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.

  • before cut.
  • Restored use of Page Up and Page Down to scroll horizontally.
  • Bug Fixes since 1.2.6:
  • Labels now accept lower case "z".

  • New Mixer Board view with per-track VU meters.
  • Automatic Crash Recovery in the event of abnormal program termination.
  • Fast "On-Demand" import of WAV/AIFF files if read directly from source.
  • FLAC now fully supported. Added support for optional FFmpeg library
  • for import/export of AC3/M4A/WMA and import of audio from video files.

New in version 1.3.14 RC1 (December 8th, 2011)

  • 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.
  • Play and Record shortcuts did not work after clicking in Device Toolbar.
  • 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.
  • Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
  • 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).

New in version 1.3.13 RC2 (April 5th, 2011)

  • 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.
  • 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. 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.
  • Other bug fixes:
  • Nyquist effects: fixes for crashes, incorrect slider behaviour and better
  • support for backslashes, double quotes and Unicode characters.
  • Processing of VST effects was substantially slower than
  • in previous versions of Audacity.
  • 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.
