About
Ardour is a fully featured, free and open-source digital audio workstation (DAW) built for professional-grade audio production on Linux, macOS, and Windows. Designed with power users in mind, Ardour provides an end-to-end workflow for recording, editing, mixing, and mastering audio and MIDI projects of any complexity. At its core, Ardour supports an unlimited number of audio and MIDI tracks and busses, non-destructive (and destructive) recording at any bit depth and sample rate, and dozens of file formats. Its editing toolkit offers cut, move, stretch, copy, paste, crossfade, quantize, transpose, and swing operations — all with unlimited undo/redo — inside a single unified window. The mixer engine delivers floating-point fidelity, flexible anywhere-to-anywhere signal routing, and full support for AudioUnit, LV2, VST2/VST3, and LADSPA plugins, including MIDI processors and software instruments. Every plugin parameter can be automated and controlled via MIDI Learn. For synchronization, Ardour offers best-in-industry MIDI timecode and LTC sync, JACK transport, MIDI Machine Control, Mackie Control protocol support, and OSC control. A built-in video timeline allows soundtrack editors to import video, display frame-by-frame thumbnails, and lock audio regions to picture. Ardour is ideal for audio engineers requiring complete control, musicians capturing live performances, film/video soundtrack editors, composers working with hardware synthesizers or software instruments, and podcasters managing complex multi-mic sessions. The integrated Freesound.org library provides quick access to thousands of free clips and sound effects.
