[edit] Description

Ableton Live is an audio production workstation for Windows and OS X. As the name suggests, the emphasis of the software is on live musical performance.

Live uses a range of proprietary formats to store audio files and playback information.

[edit] Formats

[edit] Ableton Device Group

Ableton Device Group (.adg) files hold preset data for Racks (chains of instruments, audio / MIDI effects, etc.).

[edit] Ableton Device Preset

Ableton Device Preset (.adp) files hold preset data for individual devices (instruments, effects, etc.).

[edit] Ableton Groove File

Ableton Groove Files (.agr) are used to modify the timing and "feel" of audio and MIDI clips. According to the Using Grooves section of the manual, these can be essentially converted to and from MIDI clips.

[edit] Ableton Live Clip

Ableton Live Clip (.alc) files contain references to audio samples (in WAV or AIFF format) used for a specific clip, along with FX and channel settings where appropriate (according to this forum thread)

[edit] Ableton Live Set

Ableton Live Set (.als) files contain the layout of a set (tracks, devices, audio clips, etc.) created using the Ableton Live audio production software.
