Ardour 8.6

Ardour is an audio processing and editing application. It integrates broad hardware support, JACK and ALSA backends, flexible recording features, multi-channel nesting, import and exporting various file formats, comes with ready to use samples from freesound.org. It has a pretty editing UI, mixing, routing, monitoring, panning. Ardour allows non-destructive and non-linear editing, can be used for augmenting audio layers in video files even. And comes with many effect, input and output plugins. It's open source, but asks for donations on the download page for prebuilt binaries.

Recent Releases

8.614 Apr 2024 17:31 major bugfix: 8.6 is a hotfix release to correct a drawing bug that was not noticed/fixed before 8.5. It also corrects a crashing bug that can occur when using JACK2. Ardour 8.6 is available now for Linux, Windows, and macOS. This is another "small" release without major new features, largely because our two lead developers continue to be busy with things linked to future releases. However, 8.6 does see a fix for a problem in 8.4 that affected many Linux users (a crash whenever a file selection dialog was opened, triggered by the presence of certain icon files on their version of Linux).
8.511 Apr 2024 06:25 major feature: Improvements Improvements to AAF import support. Make it easier to use Ardour --gdb on linux by handling SIG32 automatically. Do not include hidden plugin in plugin-list. Use session-file version as part of backup file names in backup/ folder. General MIDI MIDNAM file now includes drum names. Display grid lines for triplets/quintuplets/septuplets. When nudging a single control point, locate to the new position to make the time/position clear. Add support for pitch bend to Reasonable Synth. Bug Fixes Fix Snapping quintuplets and septuplets 2x factor grid: fix quintuplets 2x factor (septuplets still don't draw properly). Update unversal legal path rule for windows (to avoid illegal file names there). Add missing horizontal separator after last track header. Work around itstools bug #9648. Fix undefined symbol when built with VST3 disabled. Disable broken septuplet option. Adding new route in front now works as intended (#9651). Fix jump to next/prev bar. Discard untitled sessions even when not quitting Ardour. Refilling buffers after edits now avoids gaps in audio data. Set correct Timecode widget name. Half-baked automation-point nudge. Fix loading session by relative path. Accumulate IO port-change signals return values. Prevent crashes when trying to add/remove IOPlug ports. Fix a -Wincompatible-pointer-types. Ellipsize inactive track-header name-label (#9674). Prevent double-click on the pianoroll to toggle track height. Clarify that there are no archive file format options. Fix crashing file dialogs - fdopen(3) requires _POSIX_C_SOURCE. Set default time domain to Audiotime to sidestep various MusicTime issues. Fix solo controller for Monitor bus. Fix potential memory corruption in AVX512f DSP.
8.421 Feb 2024 11:50 minor feature: Mixer interaction fixes (interaction consistent use of button press and release). Lots of miscellaneous color and drawing tweaks. AAF import now (mostly) functional. This is still somewhat experimental, but we would welcome feedback.. Add metadata to session property editor so that search "works" there. Dummy Backend: allow testing with some prime buffersizes. Region groups: do not group multiple takes on a single track. Add a tooltip to describe ops on the pianoroll header, incl note select. Don't show plugin preset UI for plugins without controls. New "adwaita" color theme (based on the GNOME Adwaita desktop theme). Don't show automation of hidden plugins. Set default MIDI CC values to be more in line with MIDI specs. MIDI notes that were already on/down when recording starts are now captured. This change needs a more refined version, particularly to retain the velocity of these "early" notes, but this is a step in the right direction.
8.320 Feb 2024 05:45 minor feature:
8.213 Dec 2023 03:15 major feature: Note tupling: inspired by a feature in the new Ableton Live 12 - while editing MIDI, select one or more notes, then press "s" to split each note into two equally sized parts. Press "s" again to split into 3, then 4, 5 and so on. Reverse the process with shift-S. Use "j" to join selected adjacent notes back together. As you can see in this video this can be a very powerful technique for working with complex rhythms. No-strobe option: a new user preference that can disable all "flashing" and "blinking" elements of Ardour's GUI, intended for users with sensitivity to this sort of visual input. If enabled, clocks do not run, no buttons blink, and meters do not move. Support for the Solid State Logic UF8 (a USB MIDI / Mackie Control Protocol device) Support for the Novation LaunchPad X and LaunchPad Mini devices. This completes Ardour's support for the full range of Novation LaunchPad mk3 devices. As with the Launchpad Pro support introduced in v8.0, Ardour's support follows the Novation user manual for the X. We decided to make the Mini behaves identically: it lacks some built-in button labels compared to the X, but in other respects shares the same layout, at a smaller scale. Improvements and Bug Fixes Change default sample rate to 48kHz. Keep track of the visibility of GUIs for LV2 plugins using the externalUI extension. When importing tempo maps from Standard MIDI Files, insert the tempo map at the correct position (not always at zero). When editing MIDI notes, show note length with verbose cursor. Add Mute button to recorder view. Allow clearing LV2 plugin scan info. Always allow playback even if there is no session start/end defined yet. Improve straight line drawing for note velocity. Handle situations where user's value for XDG_CONFIG_HOME is not an absolute path. Optimize tempo map operations for trivial (and overwhelmingly common) case of 1 tempo and 1 meter. Control Surfaces and Devices Numerous Fixes for Console

5.331 Aug 2016 01:05 minor feature: Ardour 5.3 is almost entirely a bug fix release that corrects a number of issues noticed and corrected since 5.1. There was no 5.2 release, due to a mistake during the release process. Fixes: Ensure click free bypass for all a-* plugins. Enable normal operation when using an audio interface on OS X that is split into two "halves" (playback and capture), both with the same name. The Behringer UMC22 is one such device, but there are others already known to use this wierd and poor design. Our assumption is that the device(s) do not use the same sample clock for playback and capture. Improve layout of a-eq GUI. Update CC automation menu on when track selected channels change. Building with support for Windows-VST on Linux now works again. Correct "focus-on-clock" behaviour (bound to keypad divide key by default). New Stuff: Extend lua bindings (processor selection, plugin-info). Single action/button punch in/out feature (available for control surface use or via shortcuts).
