Audacity

Audacity is a desktop application for recording, editing and analyzing sound. Work can begin with a recording or an existing audio file, including spoken material, music and other recordings. The website provides Windows, macOS and Linux versions and lists formats such as WAV, MP3, FLAC and Ogg for audio work and file conversion within the application.

The editing interface represents sound as a waveform. Users can select a time range to remove it, move recorded or imported clips to different positions or tracks, and split or trim individual clips. Speed and pitch have their own controls. These operations reorganize the length, sequence and characteristics of the material at the clip level.

Audacity also offers spectrogram displays and analysis through Vamp plugins. Effect extensions include VST3 and Nyquist plugins. The homepage separately describes audio.com as an online companion for sharing, publishing and collaboration. The desktop audio editor and that online service thus provide related but distinct entry points for preparing sound and making completed or ongoing work available online.
