ASD files are analysis files automatically created by Ableton Live that store metadata about audio files, including warp markers, tempo information, and waveform analysis data.
What Are ASD Files Used For?
ASD files serve as companion files to your audio samples, storing:
- Warp marker positions and settings
- Waveform analysis data
- Clip gain and pitch settings
- Browser preview settings
- Transient markers
These files ensure that when you reopen a project or reload a sample, all your warping and analysis settings remain intact, saving time and maintaining consistency in your workflow.

FAQs
Where are ASD files stored?
ASD files are stored in the same directory as their corresponding audio files.
Do ASD files affect audio quality?
No, ASD files only store metadata and don't affect the actual audio quality.
What happens if I delete an ASD file?
Ableton will create a new ASD file when you next load the audio, but you'll lose any custom warp markers or analysis settings.
Can I share ASD files with other users?
Yes, but they're only useful if the other user has the exact same audio file.
Do MIDI files have ASD files?
No, ASD files are only created for audio files since MIDI doesn't require waveform analysis.
How much disk space do ASD files use?
ASD files are typically small, usually between 1-100KB depending on the audio file length.
Can I disable ASD file creation?
Yes, in Settings > File & Folder by unchecking "Create Analysis Files".
What happens if I move an audio file without its ASD file?
Ableton will create a new ASD file when you next load the audio, resetting all analysis settings.
Can I edit ASD files directly?
No, ASD files are not meant to be edited directly. All changes should be made through Ableton's interface.
Do ASD files work across different versions of Ableton?
Generally yes, but occasionally major version updates might require reanalysis of audio files.
