Ardour is a full-featured, free and open-source hard disk recorder and digital audio workstation program suitable for professional use. It features unlimited audio tracks and buses, non-destructive, non-linear editing with unlimited undo, and anything-to-anywhere signal routing. It supports standard file formats, such as BWF, WAV, WAV64, AIFF and CAF, and it can use LADSPA, LV2, VST and AudioUnit plugin formats.
This project allows more audio professionals to be able to work with FLOSS software, instead of only having proprietary options.
