Free, open source, cross-platform audio software. Audacity is an easy-to-use, multi-track audio editor and recorder for Windows, macOS, GNU/Linux and other operating systems. Developed by a group of volunteers as open source. Audacity can record live audio through a microphone or mixer, or digitize recordings from other media. Import, edit, and combine sound files. Export your recordings in many different file formats, including multiple files at once. Supports 16-bit, 24-bit and 32-bit. Sample rates and formats are converted using high-quality resampling and dithering. Support for LADSPA, LV2, Nyquist, VST and Audio Unit effect plug-ins. Nyquist effects can be easily modified in a text editor – or you can even write your own plug-in. Easy editing with Cut, Copy, Paste and Delete. Also unlimited sequential Undo (and Redo) in the session to go back any number of steps. Real-time preview of LADSPA, LV2, VST and Audio Unit (macOS) effects. Plug-in Manager handles plug-in installation.

AudioDesk provides all of the high-end features you'd expect in a professional workstation application, like 24-bit/192-kHz recording and real-time, 32-bit effects processing. The software includes multi-track audio editing, sample-accurate placement of audio, a complete virtual mixing environment with up to 64 stereo busses, automated mixing, graphic editing of mix and effects automation, scrubbing, trimming, spotting, crossfades, support for third-party AU, VST2, and MAS effects plug-ins, unlimited digital track bouncing (including effects and automation), and much more. AudioDesk does not place artificial restrictions on the number of tracks you can work with. Unlimited audio tracks means AudioDesk is ready for as many tracks as your computer will allow. Unlike other audio sequencers, AudioDesk places no limits on the number of tracks you can use simultaneously.
