Ardour
Ardour is an open-source digital audio workstation (DAW) (audio production software) for recording, editing, mixing, and mastering multitrack audio and MIDI on Linux, macOS, and Windows.
- Multitrack audio and MIDI recording, editing, and mixing (audio production)
- Non-destructive, sample-accurate editing with automation and routing (audio workflow engine)
- Plugin hosting for LV2, VST, AU, and other supported formats (audio plugin host)
- Flexible bus routing, monitoring, and session management (studio routing and session control)
- Import/export with various audio file formats and standards (media interchange)
More About Ardour
Ardour is a digital audio workstation (audio production software) designed for recording, editing, mixing, and mastering audio and MIDI material. It targets use cases such as music production, film and video post-production, broadcast audio, and other studio workflows that require multitrack recording and precise control over sessions. The project focuses on providing an extensible environment on Linux, macOS, and Windows with access to common plugin ecosystems and audio hardware interfaces.
The core of Ardour provides multitrack recording and playback (audio and MIDI engine), with support for multiple inputs and outputs, punch in/out, and latency compensation. Its editing features (non-linear editing) include non-destructive, region-based operations, sample-level edits, crossfades, clip layering, and quantization tools for audio and MIDI. Automation (mix automation) is available for parameters such as volume, pan, plugin controls, and sends, and can be drawn, edited, and played back with various modes.
Ardour includes a routing and mixing system (studio mixer and routing) with tracks, buses, aux sends, subgroups, and a master bus. The mixer provides channel strips with inserts, sends, EQ and dynamics via plugins, metering, and monitoring controls. The routing grid supports complex internal signal paths and external I/O, enabling connections to audio hardware, control rooms, and outboard gear. On Linux, Ardour integrates with JACK (audio connectivity) for low-latency routing between applications and hardware; on other platforms it connects to the native audio backends.
Plugin support (plugin host) includes LV2 on all supported platforms and VST on compatible systems, as well as AudioUnits on macOS. This allows use of third-party processors, instruments, and metering tools. Ardour also provides built-in processors and utility tools (built-in effects and utilities) exposed as plugins within the mixer. MIDI sequencing (MIDI production) supports instrument tracks, piano-roll editing, step input, controllers, and tempo and meter management.
For session management and interchange (workflow and collaboration), Ardour uses a session-based project structure with support for snapshots, versioning within a session, and templates for recurring setups. It can import and export audio in multiple formats and sample rates (media encoding/decoding), and supports timecode and synchronization features (sync and transport control) relevant for video and post-production workflows when used with external tools.
Enterprises and institutions use Ardour (enterprise and institutional deployment) in environments where open-source tooling, Linux-based systems, or custom workflows are required, such as education, research labs, independent studios, community radio, and some broadcast or media facilities. Its licensing under the GNU General Public License (open-source licensing) allows inspection and modification of the source code, which supports integration into tailored audio environments and the development of extensions, plugins, or custom builds.
