The .ALS file format is used by the popular music-creation software Ableton Live. Files with this extension are Ableton Live projects that have not yet been mixed down to an audio file. Export your ALS files to the WAV format using Ableton Live to allow them to be played on a media player or burned as an audio CD.
Launch Ableton Live and load your ALS project file.
