Ardour is a hard disk recorder and digital audio workstation application that runs on Linux, macOS, FreeBSD and Microsoft Windows.

It includes a crossfade editor and beat detection, unlimited undo/redo, and a "snapshot" feature for saving the current state of a session to a file.

[7] Ardour attempts to adhere to industry standards, such as SMPTE/MTC, Broadcast Wave Format, MIDI Machine Control and XML.

It is theoretically possible to use plugins created for Windows in the VST2 format on Linux with the help of Wine, but the project team does not recommend it.

[19] Solid State Logic employed Paul Davis to work full-time on Ardour during the development of version 2, until the end of 2006.

Harrison's Mixbus DAW, LiveTrax[21] front-of-house multi-track recorder, and their destructive film dubber, the Xdubber, are based on Ardour.

The Xdubber was a customizable platform for enterprise-class digital audio workstation (DAW) users.
