BPM Player

About BPM Player

BPM Player does one job: you type a target BPM and the whole playlist plays at it. Every track is time-stretched in real time and keeps its original key. The number stays where you put it; the track changes, the tempo doesn't.

BPM comes from the file's tags; untagged files get a marked estimate with one-click halving and doubling. Hold Space to hear a track at its original tempo, release to snap back. Park a reference track above the playlist and A/B against it at the same tempo. Drag rows out to Finder or an Ableton Live track, untouched.

Built for DJs auditioning tracks at set tempo and for dance teachers running a class on one pulse. Plays MP3, WAV, FLAC, AIFF, M4A, AAC, OGG and Opus. Free, notarized, Apple Silicon, no account, no tracking.
