Instantly detect the tempo and musical key of any audio file — 100% free, no signup.
Once you know the BPM and key, pick a vocal preset workflow that fits the session. The preset gives you the DAW chain; the detected key gives you the right tuning and pitching direction.
Use the detected key for tuning, then start the mix from an editable vocal preset. If a ready made chain does not fit your recording, the custom preset service builds one around your voice and session.
Use this as a key finder, BPM finder, song key detector, and tempo detector for beats, loops, remixes, and vocal sessions. After the key is detected, tune vocals in the browser or choose a vocal preset chain that fits the song key and genre.
The detector is most useful when the result immediately informs tuning, remixing, sample flipping, DJ prep, or vocal preset selection.
