Ardour capabilities include: multichannel recording, non-destructive editing with unlimited undo/redo, full automation support, a powerful mixer, unlimited tracks/busses/plugins, timecode synchronization, and hardware control from surfaces like the Mackie Control Universal. If you've been looking for a tool similar to ProTools, Nuendo, Pyramix, or Sequoia, you might have found it.

Above all, Ardour strives to meet the needs of professional users. This means implementing all the "hard stuff" that other DAWs (even some leading commercial apps) handle incorrectly or not at all. Ardour has a completely flexible "anything to anywhere" routing system, and will allow as many physical I/O ports as your system allows. Ardour supports a wide range of audio-for-video features such as video-synced playback and pullup/pulldown sample rates. You will also find powerful features such as "persistent undo", multi-language support, and destructive track punching modes that aren't available on other platforms.

Additions and Changes:

• add visualization of signal flow within tracks and busses
• Various improvements to panning
• add stereo-balance panner
• right click on panner to select a different (compatible) paner
• major overhaul to VBAP panner so that it works
• panner GUI tweaks
• Sends now have their own panner
• Send panner may be (un)linked with the main panner via the context menu of the send. If linked, the send's panning follows the main panner.
• Various improvements to import and auditioning
• Add MIDI auditioning (using Ardour's builtin "reasonableSynth")
• Consider all tracks in a MIDI (SMF) file
• allow auditioning via the monitor section to work (and make it the default when using a monitor section)
• add a seek/locate slider to the import auditioner
• auditioning now uses sample rate conversion when necessary, so that auditioned files are always played back at the correct pitch/speed

• do not lock audio to video when extracting only the audio from a video file
• re-enable export file tagging and fix export format dialog inconsistency
• fix audio cross-talk between tracks that occured when using 1in/2out tracks.
• fix the "replicate missing channels from regions" option
• fix text "bleeding" in various buttons
• provide some level of compatibility with aubio 0.4. Ardour should still be built using aubio 3.2.
• improve rendering of faders
• add M-Audio 2496 to the list of devices recognized to have a "control app"
• fix behaviour of plugin parameter sliders for ranges [0..]
• new MIDNAM files for Moog MF-104M and MF-108M
• add support for MIDNAM controller labels
• document MIDNAM controller values for Moog Minitaur
• fix display isues with editor mixer strip
• fix 32 bit export
• fix crash when adding processors which change overall track I/O configuration
• fix deadlock when removing monitor section
• ignore additional channels during AFL/PFL (if the track/bus has more channels than the monitor section, ignore the additional channels)
• fix output metering for Sends
• new MIDI binding map for Roland V-Studio 20
• new very basic MIDI binding map for M-Audio Oxygen-25
• fix display of pan automation and MIDI fader automation
• working support for VST "timeinfo" delivery to plugins (Windows VST and Linux VST)
• fix crash when instrument plugins fail to load
• fix potential for duplicate Send IDs
• auto connect preferences now respected for MIDI tracks
• use all outputs of VST plugins, not just the input count
