What you'll see
Your project opens as its arrangement: the tracks down the left in their colors, and their clips along the bars with their notes drawn small and the waves of their audio, under the tempo and markers.
- Every track and clip • Zoom from the whole song to a beat
- Plugins and samples • A tab each, missing samples marked
- Play • The notes in General MIDI sounds, Audacity's own mix
- Export • Save as MIDI, WAV, MP3 or CSV
About ALS
Ableton released Live in 2001 for performing and producing electronic music, and its Live Sets became the projects of countless producers, DJs and live acts. Live runs on Windows and the Mac, in Intro, Standard and Suite editions, and people send .als files to work on a song together or to have it mixed.
An ALS is gzipped XML: every track with its color, group, devices and their settings, the clips of the Arrangement and of Session View with their notes, warp markers and the samples they play, the returns and the main track, the tempo, time signature and locators. The audio stays in the samples it points to, usually in the project's folder beside it.
Filepeek reads it in your browser. The Arrangement opens with each track in its color, a group's tracks under it, and the clips along the bars with their notes drawn small and the waves of the samples you drop with it. Plugins lists every device with its maker and whether it's Live's own, VST, VST3 or AU, Samples which files the set uses and which are here, and Play plays the notes with General MIDI instruments picked by each track's name. Export saves the notes as MIDI and the lists as CSV.

Questions
How do I open an ALS file without Ableton Live?
Drop it on this page or press Peek an ALS. It opens as its Arrangement in your browser, on Windows, a Mac, an iPhone or Android, with nothing to install.
Which plugins and samples does this set need?
Open Plugins to see every device on every track, with its maker and format, Live's own, VST, VST3 or AU. Samples lists each file the set plays with its path, marked found when you drop it with the set. Export saves both lists as CSV.
Why do the audio clips say Sample missing?
A Live Set only points to its audio. Drop the set with its project folder, or with the files Samples lists, and their waves show.
Where are my Session View clips?
Clips that sit only in Session View have no place on the timeline, so the note above the tracks counts them. Every clip in the Arrangement shows where it plays.
How do I get the MIDI out of a Live Set?
Open it, choose Export, then Save the notes as MIDI. Each track's clips become a track of notes, where the Arrangement plays them, with the tempo and the locators.
