Why our BPM is more accurate
Most online tempo detectors just look for periodicity in loudness — and often get it wrong by a factor of two (60 instead of 120) or trip on syncopation. Layrix uses the beat_this model, which finds the track's actual downbeats rather than any energy peak, so the tempo matches what DJ software or manual tapping would show.
Matching two tracks or building a playlist? Also check the key in Camelot notation — together these two numbers fully describe a track for harmonic mixing. Hunting for loops or samples? Try splitting into stems to pull a clean drum track at the tempo you need.
Want the chords for that tempo too? Chord recognition from audio works on the same file, no re-upload needed. All tools live on the Layrix homepage.
How is BPM calculated?
The beat_this model finds the track's actual downbeats (not just loudness peaks) and computes the exact tempo from the intervals between them.
Can it be off by a factor of two (e.g. 70 instead of 140)?
That's common with simple amplitude-peak detectors. Layrix tracks the actual beat, so such errors are rare, though very loose rhythms can still introduce some margin of error.
Is it free?
Yes, BPM detection is free with no signup, with a 7-minute-per-file limit.
