Audacity Overview
Audacity for Mac records and edits multi-track audio with unlimited undo, built-in effects, and detailed analysis tools, all for free. It covers the full loop from recording through cleanup to export: a compressor and limiter, noise reduction, pitch and speed changers, a spectrogram view, and a frequency-analysis window come built in, so most editing work doesn't need a single paid plugin. Multi-format plugin support extends it when you do need something specific, and cloud saving through Audio.com lets you back up and collaborate on a project without a separate service. Podcasters cleaning up an interview, musicians recording and mixing multi-track demos, and field recordists capturing and analyzing environmental or ambient sound all use it as their go-to audio editor.
Why Choose Audacity Free Audio Editor & Recorder App
The effects and analysis toolkit is where this earns its reputation. A compressor, limiter, noise reduction, and pitch and speed changers cover the editing basics that other free editors often lock behind a purchase, and the spectrogram and frequency-analysis views give you a genuine look at what's actually happening in a recording, useful for tracking down a hum or a clipped section that's hard to hear but easy to see. The built-in toolkit isn't a ceiling either: Audio Unit plugins, the format built into macOS itself, work alongside VST3, LADSPA, LV2, and Nyquist, so effects from GarageBand or Logic Pro's plugin library can often slot straight into a project. All of it, every effect and analysis tool listed, is free and open source under the GPL v3, with the source code open for anyone to inspect or modify.
Two things matter specifically if you're on a Mac right now. OpenVINO AI plugins became available specifically for macOS, adding AI-powered music separation, noise suppression, music generation, and audio super resolution directly into the effects menu, tools that used to require a separate paid service. Transcription runs the same way: speech converts to text using the Whisper model entirely on your Mac, with no file uploads, no minute caps, and no monthly fee attached. And beyond the standard universal DMG covering both chip types, separate Apple Silicon-only and Intel-only downloads are available too, in case you'd rather install the build matched exactly to your Mac's processor. Automatic beat detection and time-stretching round things out for anyone syncing clips to a song's tempo rather than eyeballing the waveform.

What's New in Audacity 3.7.8 Version
Version 3.7.8 shipped June 11, 2026 as a patch release, part of the 3.7.x maintenance series while the team develops Audacity 4.
- Fixed an exception thrown when pasting into a newly-created track.
- Fixed preset loading for the Distortion effect.
- Fixed scripting and macro behavior around tone generation, waveform scale settings, clip names, and clip-boundary commands.
- Added an option to choose where silence gets truncated in a selection: start, middle, or end.
- Improved multichannel FLAC import and fixed broken envelopes that could occur after joining clips.
This follows version 3.7.6, which added FFmpeg 8 support and a new Spectrogram Wavelet analysis mode.
Supported macOS Versions
Audacity 3.7.8 is officially tested on macOS 14 and macOS 15, and the developer states it should also work on any release back to macOS 10.11 El Capitan, though those older versions aren't specifically tested. One detail worth knowing: macOS 10.14 and earlier don't support the universal DMG, so those Macs need the separate Intel-only installer instead. Basic recording and editing run comparably on Apple Silicon and Intel, but the local AI features are a different story: transcription runs a Whisper model directly on your Mac, and that kind of on-device inference genuinely benefits from Apple Silicon's Neural Engine, so expect noticeably faster results on an M-series chip than on older Intel hardware. The developer also notes that Audacity needs fast, uninterrupted access to a hard drive or SSD to record and edit reliably; network storage, consumer-grade external drives, and USB thumb drives may cause dropouts or instability during recording.
How to Download and Install Audacity on macOS?
Installing Audacity on Mac only takes a few steps after downloading, including one quick permission it needs to run properly.
- Click the Download button above that is fully secure and complete the downloading procedure.
- Open the downloaded .dmg file, then drag Audacity into your Applications folder.
- Launch Audacity from Applications. If macOS shows an "unidentified developer" warning, go to System Settings → Privacy & Security and click Open Anyway.
- Grant microphone access when prompted, so Audacity can record audio from your Mac's input devices.
- Install the optional FFmpeg library separately if you need to import or export formats like WMA, M4A, or AC3.
Once the initial setup is done, Audacity won't ask for these permissions again future launches go straight to your project.
How to Use Audacity Mac App
- Launch Audacity and click the red Record button to start recording, or import an existing audio file via File > Import.
- Use the Selection tool to highlight part of a track, then apply an effect from the Effect menu.
- Add multiple tracks to build a multi-track project, adjusting each track's volume and pan individually.
- Switch a track to Spectrogram or frequency-analysis view for a detailed look at its content.
- Export your finished project as WAV, MP3, FLAC, or another format via File > Export.
- Sign in to Audio.com from within Audacity if you want cloud saving or to collaborate with someone else on a project.
