Audacity 3.5.1 – Free audio software

Audacity 3.5.1 – Free audio software

Audacity is a free, easy-to-use and multilingual audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. You can record sounds, play sounds, import and export WAV, AIFF, AAC, MP4, Ogg Vorbis, and MP3 files, and more.

Use it to edit your sounds using Cut, Copy and Paste (with unlimited Undo), mix tracks together, apply effects to your recordings, change the speed or pitch of a recording, and really much more.

Audacity enables FLAC support. The program also has a built-in amplitude-envelope editor, a customizable spectrogram mode, and a frequency-analysis window for audio-analysis applications.

The program has  the built-in effects, including Bass Boost, Wahwah, and Noise Removal, and it also supports VST plug-in effects.

Audacity is without a doubt one of the best and easiest digital audio editors on the market and it will meet any requirement at 100% no matter if it is home or professional audio edition.

Audacity Key Features:

  • Cut, copy, splice or mix sounds together.
  • Record live audio.
  • Supports 16-bit, 24-bit and 32-bit (floating point) samples (the latter preserves samples in excess of full scale).
  • Record computer playback on Windows Vista and later by choosing “Windows WASAPI” host in Device Toolbar then a “loopback” input.
  • Import and Export WAV, AIFF, AU, FLAC and Ogg Vorbis files.
  • Convert tapes and records into digital recordings or CDs.
  • Edit WAV, AIFF, FLAC, MP2, MP3 or Ogg Vorbis sound files.
  • Import and export AC3, M4A/M4R (AAC) and WMA with the optional FFmpeg library (this also supports import of audio from video files).
  • Numerous effects including change speed or pitch and vocal reduction or isolation (given suitable stereo tracks).
  • And more! See the complete list of features.

Changes in version 3.5.1:

  • Fixed a crash on launch on macOS 11 and older.
  • Fixed the update notification looking for alpha versions instead of release versions.
  • Fixed a freeze when using macros on multiple files.

Changes in version 3.5.0:

  • 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.


  • 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!)


  • 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.


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.
  • 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.


  • Fixed a number of dialogs that were able to grow too large to fit on the screen.
  • Fixed the playback cursor sometimes desynchronizing with actual playback. (Thanks, David Bailes!)
  • Fixed the GetInfo scripting command.
  • Fixed “Reset configuration” command breaking modules preference page.
  • Fixed stereo tracks randomly splitting into mono.
  • The Export Audio -> (external program) option remembers the command line argument again.
  • Fixed the Compressor effect sometimes corrupting audio. (Thanks, David Bailes!)
  • Fixed Timer Record sometimes failing to export. (Thanks, David Bailes!)
  • Fixed incorrect level measurements for mono tracks in Noise Gate effect. (Thanks, Steve Daulton!)
  • When exporting multiple files, the mono/stereo setting is now honored properly.
  • Fixed some effects failing when language is set to German, Korean, Dutch, Slovenian, or Turkish.
  • Fixed 8 and 9 inputs not working on keyboard inputs which have AltGr+8/9 mean [ and ]. (Thanks, David Bailes!)
  • Fixed Audacity crashing when making a stereo track using keyboard. (Thanks, Joe Souza!)
  • Fixed the “Set default” button not working in the metadata editor. (Thanks, dg-no-9!)
  • Linux: Fixed a memory leak in Wayland by explicitly running on X11. (Thanks, Takahashi, Naoki!)
