Mixing and Mastering AIFind the tempo and the downbeat of any track.
Drop in a song and get its tempo back, detected from the audio itself rather than guessed from a filename or a tag.
It also finds the downbeat, so you know where bar one actually starts. That is the part that saves time when you are lining a sample up against a grid.
Key points
- Tempo detected from the audio, not from metadata.
- Downbeat position, so your grid lines up on bar one.
- Works on a full mix, a loop or a single stem.
- Free, with no token cost.
What it is good for
- Sampling and remixing. Get the tempo of a record you want to flip before you start warping it.
- DJ preparation. Confirm the BPM of a track whose tag is missing or wrong.
- Session setup. Match your project tempo to a reference or an a cappella you have been sent.
- Sync work. Check that a stem you received actually runs at the tempo you were told.
What it costs

Common questions
Why does it sometimes report half or double the tempo?
Tempo is genuinely ambiguous in some music. A track at 140 BPM with a half-time feel is legitimately 70 BPM to one listener and 140 to another. If the number looks half or double what you expect, it is usually that rather than an error.
Does it work on a track with no drums?
It can, but accuracy drops. Beat detection relies on transient energy, so an ambient or free-tempo piece may not return a meaningful figure.
Is it free?
Yes, BPM Finder costs no tokens.
