Find your track's key and BPM — free, no account

RefBooth reads your track's tempo in BPM and its musical key, including the Camelot code producers use for harmonic mixing. Where a tempo sits near a half-time or double-time boundary, the report names the alternate reading too, so a track at 64 doesn't quietly get logged as 128, or the other way round.
