Users can work with formats including MP3, M4A, AIFF, FLAC, and WAV, and with 16-bit, 24-bit, or 32-bit audio. A Spectrogram view provides a visual way to examine audio clips, while third-party plugins can add capabilities through VST3, Nyquist, LV2, and Audio Unit formats. The source code is available to view or modify under the GNU GPL, and no subscription is required. Audacity’s platform information also lists Android and iOS, but the product has no mobile version for either. Support is available through a manual, forum, and developer Discord.

Overview

Audacity has been developed since 2000 by a small remote team supported by its community. Its source code can be viewed or modified under the GNU GPL, making it a fit for users who value open-source software as well as a zero-cost editing option.

The focus is recorded audio: multitrack editing and noise reduction support practical editing work, while video synchronization can help when audio needs to align with video. The absence of MIDI sequencing matters for users composing or arranging through MIDI; Audacity is better suited to editing audio than replacing a MIDI-based production environment.

Key features

Editing and analysis

Multitrack editing gives users room to work across audio tracks, and noise reduction addresses unwanted sound. Spectrogram view adds a visual way to examine audio clips. Support for 16-bit, 24-bit, and 32-bit audio, plus high-quality resampling and dithering, makes the editor useful across a range of audio work.

Audacity supports MP3, M4A, AIFF, FLAC, and WAV. That breadth is helpful when working with common audio files in different formats. Video synchronization is also supported, though the software's lack of MIDI sequencing draws a clear line around its role.

Plugins and collaboration

Third-party plugin support covers VST3, Nyquist, LV2, and Audio Unit. Users with compatible plugins can extend their processing options rather than being limited to built-in tools. Cloud collaboration is also supported, although its practical scope is not defined; users choosing Audacity specifically for shared projects should confirm that it meets their workflow needs.

Pricing

Audacity is free for everyone, with no subscription required. Its Free plan is free and provides an open-source desktop audio editor. A second Audacity Free plan is also free, described as free for everyone. There is no paid tier to unlock additional features, so the tradeoff is not a cheaper plan with reduced capacity but a free desktop toolset whose limits include no MIDI sequencing and no mobile app.

Platforms

Audacity runs on Windows, macOS, and Linux desktop computers. Despite platform references to Android and iOS, there is no mobile version. That makes it a poor choice for anyone who needs to record or edit in a native phone or tablet app.

Who it's for

Audacity is a strong fit for people who need free desktop editing for recorded audio, want to work with common file formats, or rely on compatible third-party plugins. It is less suitable for MIDI-centered composition or mobile editing. Support is available through the manual, forum, and developer Discord.

Pros and cons

• Pros: Free and open source, with no subscription requirement, making it accessible for users who want desktop editing without ongoing software costs.
• Pros: Multitrack editing, noise reduction, spectrogram analysis, and support for several common audio formats cover a broad set of recorded-audio tasks.
• Pros: VST3, Nyquist, LV2, and Audio Unit compatibility provides ways to add third-party tools.
• Cons: No MIDI sequencing, so it is not the right choice for users who need MIDI-based composition.
• Cons: No iOS or Android app, which rules it out for mobile-first editing.
• Cons: Cloud collaboration is supported, but its scope is not defined, making it difficult to judge for teams with specific sharing needs.

Alternatives

For another free desktop editor, Ocenaudio offers a downloadable option for Linux, macOS, and Windows. Choose WavePad if you want a freemium editor across desktop and mobile platforms; its Master's Edition Annual Plan is $99 a year and includes an SFX Library and full VST support. MixPad is another freemium alternative for desktop and mobile, with a Master's Edition described as including unlimited tracks and full VST support for studios.

GoldWave is a paid alternative with a one-year license priced at $19 a year, and supports Linux, macOS, Windows, web, Android, and iOS. TwistedWave is also paid and supports desktop, web, and iOS; its first year is $99.90 a year for a Mac and Windows desktop editor. Readers comparing category options can browse Audio Editing Software or, for game-focused workflows, Game Audio Editors. Other alternatives include Pro Tools, PhotoDirector, and SADiE.

Verdict

Choose Audacity for free, open-source desktop editing with multitrack tools, noise reduction, broad audio-format support, and plugin compatibility. Look elsewhere if you need MIDI sequencing or a mobile app; those are clear limits for users whose work depends on either.
