Free BPM and key finder for DJs
Upload an MP3 or audio file. Ora DJ finds the song's BPM and musical key, maps it to Camelot, and draws its energy, beatgrid, and waveform with the same analysis engine used in Ora DJ Studio.
Your track is deleted immediately after the result.
Key, BPM, Camelot, energy, and a beatgrid on the free result. No account.

What comes back
More than a number in a tag
Tempo and downbeat
BPM includes the beat lattice, so energy can line up with the musical bars instead of an arbitrary clock.
Musical key
See the musical name and its Camelot code, then check the four nearby keys that make useful harmonic moves.
Perceived energy
The 1 to 10 score gives the headline. The green curve shows how the pressure changes bar by bar, or second by second when no reliable beat grid is found.
Three-band waveform
The waveform keeps low, mid, and high-frequency information, which makes breakdowns and fuller sections easy to spot.
Your key is only the first move
The Camelot wheel turns a detected key into a small map: stay put, move one number either way, or swap between relative major and minor.
