What is Audacity?

Audacity is an open-source audio recording and editing program that's completely free to use, with no hidden costs. It has over 100 million downloads since 2000. Podcasters, music producers, video editors, or anyone who simply wants to record speech and remove unwanted sections can manage it all with this one program, without needing an expensive DAW. The main interface works with multiple tracks; you can record from a microphone or connected audio device, then cut, move, copy, paste, or mix multiple audio layers together on a single timeline. It includes Waveform and Spectrogram tools for detailed audio signal analysis, along with built-in Normalize, Compressor, Equalization, and Noise Reduction tools. Whether you're recording voiceovers, removing noise from interviews, or balancing volume throughout a file before export, you can do it all in one place.

Importing and exporting supports WAV, AIFF, FLAC, MP3, and OGG formats. Other formats can be accessed via FFmpeg, with VST3, LV2, Nyquist, and Audio Unit plugins available on supported systems. For detailed editing, use Envelope to adjust audio levels in segments directly on tracks, or place label tracks to mark chapters and cuts in long files such as interviews or podcasts. For a lighter option focused on editing files piece by piece, other options are available. OcenAudio It's another option, while Audacity excels in multi-track applications and live recording.

Version 4 transitions to the Qt framework with a more modern interface, native high-DPI display support, and the ability to save layouts as Workspaces. The official installer now includes ASIO driver support, allowing you to select playback and recording devices matching your host and workflow. The project file uses the .aup4 format, enabling you to open and convert older .aup3 files without altering the original files. It is ideal for audio editing beginners, students editing course projects, as well as YouTubers, podcasters, and serious musicians, providing a comprehensive set of tools right from the first launch.
