Fix the BPM in Old Songs and Live Recordings
Music made before click tracks breathes. Funk, soul, disco, classic rock, anything played live: a record everyone calls "118 BPM" might really wander between 115 and 121, which means the average is a tempo the band never actually played.
What drifts, and by how much
BPM Lock finds every beat, shows you exactly how far things drift, and stretches each beat onto a rigid grid. The song holds one steady tempo from the first bar to the last, and nothing else about it changes. You see the real tempo range before you commit to anything.
What it works best on
Anything played by humans without a click: old funk, soul and disco records, live recordings, classic rock, hand-played house. These are the recordings that break auto-warp, because there is no single tempo for it to find.
Grid-quantized modern tracks pass through nearly untouched, because there is almost nothing to correct. Pitch is preserved either way, so the song sounds like the record, only steady.
Who this is for
- DJs: with the drift gone, sync, loops and hot cues behave themselves on 70s funk and disco instead of sliding out halfway through the track.
- Producers: sample and remix human-played music without wrestling warp markers. The corrected file lands in any DAW at bar 1.
- Editors and dancers: a version of the song where every single bar is exactly the same length.
