Ardour is a digital audio workstation. You can use it to record, edit and mix multi-track audio. Produce your own CDs. Mix video soundtracks. Experiment with new ideas about music and sound. Generate sound installations for 12 speaker gallery shows. Have Fun.

Ardour capabilities include:

• Multi-channel recording.
• Non-linear, non-destructive region based editing with unlimited undo/redo.
• Full automation support.
• A mixer whose capabilities rival high end hardware consoles.
• Lots of plugins to warp, shift and shape your music.
• Controllable from hardware control surfaces at the same time as it syncs to timecode.

New in v2.8.4

• New Features: Plugin manager now has a "hide" option so that you can control which plugins show up in the plugin menus.
• New Features: New "by category" plugin menu, to complement the "by creator" one that already existed.
• New Features: If auto-play is enabled, defining or changing a range selection will immediately start playing it.
• New Features: New action, ToggleRollMaybe, which leaves loop play or range play mode but without stopping the transport (Ctrl/Cmd-Shift-space by default).
• New Features: PortInsert GUIs now have a built in hardware latency "ping" tester, modelled on Fons Adriennsen's jdelay. This can accurately measure the roundtrip signal latency of your insert and sets the latency that JACK sees. You can now use external h/w processing and get sample-accurate latency compensation within Ardour.
• New Features: New Region Layering Editor. This is accessed via the region context menu, and provides an easy way to modify the layering of regions at a given location (it will only show in the menu if there is more than one region under the mouse pointer). It can be used as an excellent tool for comping loop recording or overdubs in general.
• Critical Fixes: Fix BWF header contents.
• Critical Fixes: Fix crash caused by auto-saving after unloading a session.
• Critical Fixes: Fix crash caused by using an audio interface without inputs or outputs.
• Critical Fixes: Fix crash caused by data overrun when generating peak files.
• Critical Fixes: Fix crash bug caused by having no outputs on a track or bus and more than 1 input.
• Improvements: Make exported file name text entry "activatable" in export region dialog.
• Improvements: Correctly continue to keep sending MTC when looping.
• Improvements: Make display of files to process during import correct.
• Improvements: Window titles are now consistent (and do not include "ardour").
• Improvements: Show region sync point in the popup region editor.
• Improvements: Fix copy-drag operations when in lock edit mode.
• Improvements: Tidy up region gain line drawing so that it doesn't extend past the region.
• Improvements: Improve audio file format names shown in the interface.
• Improvements: Remove edit point clock.
• Improvements: More vertically-oriented layout of toggle controls in LADSPA editors.
• Improvements: Add key stroke (left/right arrow) and wheel (left/right, shift-down/up) scrolling in mixer window.
• Improvements: Fix missing display of plugins in the plugin manager (corrupt plugin type information).
• Improvements: Do not ignore auto-connect setting when it is disabled for a new session.
• Improvements: Do not stop at session end if synced to JACK but not the time master.
• Improvements: Save audio settings even when using FFADO.
• Improvements: Don't reset panner or plugin parameter values when switching automation to Write or Off (avoids losing a manually set value).
• Improvements: Fix "separate" edit so that regions created do not overlap by 1 sample.
• Improvements: Provide host callbacks for AU plugins to get tempo, musical time and transport information.
• Improvements: Make region "lower-to-bottom" and "raise-to-top" have persistent rather than temporary effects.
• Improvements: Sort items in the region context menu to match order in the track.
• Improvements: Cleanup of Mackie/Logic Control support to prevent it from stopping Session unloading from proceeding correctly.
• Improvements: Save and restore seamless loop setting when changing transport slave mode, since no JACK doesn't allow seamless loop.
• Improvements: When renaming tracks/busses/sends/inserts, scan everything to avoid JACK port duplicate names.
• Improvements: Display an explanation if JACK shuts down due to backend issues (e.g. another application changes the sample rate).
• Improvements: Updated Swedish and Italian translations.
