BPM detector

Trap BPM: 130–170 beats per minute

Produced at 130–170 BPM with rapid hi-hat rolls, but the kick and snare usually feel half time (65–85). Expect the detector to offer both readings. Drop a track below to see whether it sits in the usual trap range.

Detected trap at half or double?

If the detector reports 70 or 280 for a trap track, it has locked on to a different level of the beat. Set Tempo range to 120–240 so every result lands in the usual trap range. More in half-time and double-time BPM.
