What's new in Audacity 3.5.0

Apr 22, 2024
  • Major changes:
  • Cloud project saving
  • We've introduced a new cloud-saving feature that allows you to save your Audacity projects to audio.com. This allows you to work from any device, share & collaborate with others and restore previous versions if something went wrong.
  • Automatic tempo detection
  • Audacity can now automatically detect the tempo of imported loops, and adjust them to be in tempo.
  • Tempo detection is done via both audio analysis and metadata checking. If you want to prepare your loop for automatic tempo detection without relying on audio analysis, both acidizer tempo tags or simply writing "123 bpm" anywhere into the filename work.
  • Automatic tempo detection can be turned off via Preferences -> Import/Export.
  • Pitch shifting
  • You now can non-destructively change the pitch of a clip by holding Alt and pressing the Up and Down arrow keys. Alternatively, you can click on the overflow menu (...) and select "Pitch and speed...". When changing the pitch this way, an arrow in the UI indicates how much you've shifted it.
  • Other changes:
  • Additions:
  • Added an option to skip plugin scanning to Preferences -> Effects.
  • Added an overflow menu, as well as speed and pitch indicators to clips.
  • Added subtitle formats for labels. Export to WebVTT and SubRip and import of SubRip files is now supported. (Thanks, Pokechu22 and Larry Bordowitz!)
  • Changes:
  • Reworked the plugin manager.
  • Improved accessibility. (Thanks, David Bailes!)
  • When zooming in vertically (Ctrl+scroll on the vertical scale), the zeroline now remains centered. Moving the vertical zoom off-center still is possible via Shift+scroll on the vertical scale.
  • Changed the look of the selection adjust cursors (previously pointing fingers on Windows and macOS, now look like >| everywhere).
  • Changed the timeline options button from a green triangle to a settings gear. From it, you can switch between Beats & Measures or hh:mm:ss timeline rulers, set various preferences regarding to looping, as well as playhead behaviors: "Scroll view to playhead" (previously: "Update display while playing") and "Continuous scrolling" (previously: Pinned Play Head).
  • Improved BSD support. (Thanks, Brad Smith!)
  • macOS: Changed the Audacity.app icon on macOS to fit new design guidelines.
  • Reordered some menus.
  • Moved OK/Cancel buttons of effects to the bottom.
  • Removals:
  • There have been a number of removals of niche features to simplify the app. This should make the app a bit less overwhelming to use, and also will speed up future development as fewer things need to be considered.
  • Removed the read-only mouse preferences page.
  • Removed Printing options.
  • Removed Screenshot tool. To make a screenshot, use Win+Shift+S (Windows) or Cmd+Shift+4 (Mac) instead.
  • Removed Karaoke view.
  • Removed the "solo=none" preference.
  • Removed timeline tooltips preference.
  • Removed "dragging selection edges" preference.
  • Removed some warning dialogs and associated preferences.
  • Removed "scrolling left of zero" preference.
  • Replaced "Advanced Vertical Zooming" with new always-on behavior.
  • Removed some vertical zoom presets.
  • Removed EQ XML to TXT converter, which was needed for the Audacity 2.3 -> 2.4 transition. It is now a plugin instead, downloadable at https://plugins.audacityteam.org/additional-resources/eq-curves/eq-xml-to-txt-converter.
  • Removed the "Vocal reduction and isolation" effect. As a replacement on Windows and Linux, the Intel OpenVINO plugins work better and on a wider array of content, including mono tracks. The old effect still can be downloaded from https://plugins.audacityteam.org/nyquist-plugins/effect-plugins/filters-and-eq#vocal-reduction-and-isolation
  • Bugfixes:
  • Fixed a number of dialogs that were able to grow too large to fit on the screen.
  • 2133 Fixed the playback cursor sometimes desynchronizing with actual playback. (Thanks, David Bailes!)
  • 3723 #5615 Fixed the GetInfo scripting command.
  • 5283 Fixed "Reset configuration" command breaking modules preference page.
  • 5389 Fixed stereo tracks randomly splitting into mono.
  • 5500 The Export Audio -> (external program) option remembers the command line argument again.
  • 5670 #3903 Fixed the Compressor effect sometimes corrupting audio. (Thanks, David Bailes!)
  • 5580 #4952 Fixed Timer Record sometimes failing to export. (Thanks, David Bailes!)
  • 5681 Fixed incorrect level measurements for mono tracks in Noise Gate effect. (Thanks, Steve Daulton!)
  • 5750 When exporting multiple files, the mono/stereo setting is now honored properly.
  • 5848 Fixed some effects failing when language is set to German, Korean, Dutch, Slovenian, or Turkish.
  • 5868 #1548 Fixed 8 and 9 inputs not working on keyboard inputs which have AltGr+8/9 mean [ and ]. (Thanks, David Bailes!)
  • 5858 Fixed Audacity crashing when making a stereo track using keyboard. (Thanks, Joe Souza!)
  • 5976 Fixed the "Set default" button not working in the metadata editor. (Thanks, dg-no-9!)
  • 5977 Linux: Fixed a memory leak in Wayland by explicitly running on X11. (Thanks, Takahashi, Naoki!)

  • #1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
  • #1477: Filter Curve EQ will crash if there is an envelope point outside of the selection
  • This fix re-introduces an earlier, but way less destructive bug:
  • bugzilla 208 / #1500: Some effects delete Envelope Control Points, or do not move them when timeline changes

  • Highlighted Issues:
  • Below are listed what we believe are the most common and important issues with 3.0.3 for most users.
  • Accessibility:
  • Less of Audacity is properly accessible to visually impaired users than we would like. Currently the best supported platform for accessibility is Windows. We lost a lot of custom accessibility programming when we had to move to a more recent version of the wxWidgets library.
  • Internationalization:
  • Audacity is only partially translated in many languages. We also have some issues, for example, with Right-To-Left Languages.
  • Selected Bugzilla-Tracked Bugs:
  • If Temporary files directory is set to be unwritable then Audacity has a catalog of cryptic unhelpful errors

  • Selected Bugzilla-Tracked Bugs:
  • "Failed to open the project database"
  • Enh: De-clutter Plug-in Manager

  • 2720 - Cannot open project that's in a read only folder - error message vague
  • 2722 - Noise Gate fails on a one hour stereo selection
  • Some Known Issues in 3.0.1:
  • We have two significant bugs we would like help in tracking down:
  • Audacity may occasionally report "Failed to open the project database". We don't think this is causing people to lose data.
  • Audacity may offer to 'recover' a project at start up, when there is nothing to recover.

  • That annoying message from Apple saying: “32-bit support will be going the way of the dodo”, no longer shows when you install Audacity on Mac. The new 64-bit Audacity works with 64-bit libraries. To use FFmpeg or MP3 libraries with 64-bit Audacity, you will need to download the updated 64-bit versions.
  • On Windows, you may find that recording is disabled until you change Windows permissions for the microphone! That’s a security feature introduced by Windows. This affects all versions of Audacity, and affects many other audio programs.
  • New:

New in Audacity 2.2.1 RC 1 (Nov 24, 2017)

  • IMPROVEMENTS:
  • Waveform colorways:
  • You can optionally change the colorway of the waveforms displayed in your project. The setting is per track and not per project so you can have multiple colorways in the same project as in the image below.
  • Four colorways are available with the color selection made from the dropdown menu in the track's Track Control Panel.
  • "Save Other" reverts to "Export" in the File menu:
  • When we made the menu changes for 2.2.0 we introduced an entry into the File menu called "Save Other" which led to a sub-menu for exporting various audio formats.
  • Many users were confused by this change and found it hard to find where they could export audio from. So for 2.2.1 we have changed that menu entry to be File > Export.
  • OTHER CHANGES:
  • Bug Fixes:
  • We fixed a bug on Mac that caused Audacity to crash with certain Chain files. Plus we fixed another Mac bug whereby opening a second project from Mac's Finder produced a second inaccessible instance of Audacity

New in Audacity 2.1.3 (Mar 17, 2017)

  • IMPROVEMENTS:

  • New Generator for Sample Data Import
  • New and changed shortcuts:
  • ALT + RIGHT to Move to Next Label and ALT + LEFT to Move to Previous Label. These shortcuts allow the name of the label and its order in the labels in that track to be read by screen readers. As well as moving the edit position, these shortcuts jump playback to the requested label.
  • The shortcut for Play/Stop and Set Cursor has changed from SHIFT + A to the more easy to use X.
  • New and changed menu items:
  • New Edit Menu items "Store Cursor Position" and "Select > Cursor to Stored Cursor Position" (during transport, the position of the playback or recording cursor is stored)

  • IMPROVEMENTS:
  • Effects:
  • Noise Reduction defaults changed.

  • 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.

  • 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.

  • 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:

  • 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.

  • 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.

  • 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 Audacity 1.3.13 RC2 (Apr 5, 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.

  • 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.
