The Method Behind the Match
How the Engine Works
Detect the Tempo
The continuous engine listens via mic or browser audio, analyzing beat intervals in real-time. Alternatively, tap along, type a BPM, or search our 29,000+ song catalog.
Read Multiple Signals
BPM, time signature, energy, and mood are all detected independently. The dashboard's gauges show each signal as a separate instrument so you can tell which one is leading the classifier.
See the Dances Light Up
'Sweet spot' means the music sits dead in the dance's tempo range. 'Good fit' is solidly within range. 'Near miss' shows alternatives at the edges. The recommendation tiers re-rank live.
About the Song Catalog
Song Search queries a library of over 29,000 songs tagged by dance style and BPM. Results appear as you type. If your song isn't indexed yet, the Continuous Engine or Tap Tempo will get you a reliable BPM in seconds.
