GetLiveBPM Get the BPM the moment you hear it.
Point your phone's mic at a speaker or tap along and get an accurate tempo reading in seconds. A neural network runs entirely on your device, so your audio never leaves your phone.
Features
Listens to live sound
Point your phone's mic at a speaker, a band, a DJ set or an instrument. The detector locks onto the beat and reports the BPM with decimal precision.
No audio? No problem.
Tap along to a beat in your head and get an instant average. Auto-resets if you pause, so you can keep refining your estimate.
See how the tempo moves
A live chart tracks every reading over the last few minutes, perfect for spotting tempo drift in a rehearsal or a DJ set.
How it works
Capture
Your phone's mic feeds a rolling 12-second buffer at the device's native sample rate.
Transform
Resample to 11.025 kHz and take the log-mel spectrogram (256 frames x 40 bins).
Predict
A compact AI model outputs a 256-class softmax over BPM values from 30 to 285.
Refine
Parabolic interpolation around the peak gives a decimal BPM reading, not just the nearest integer.
