What is a beat finder?
A beat finder analyzes an audio file and locates the time position of every beat or drum hit. Unlike a BPM finder - which tells you the overall tempo as a single number - a beat finder gives you the exact timestamp of each beat, so you can sync cuts, animations, or cues to the music.
Beat Finder runs entirely in your browser using the Web Audio API. Your audio is never uploaded to a server - everything is processed locally on your device.
It works best on songs with a clear, steady drum beat. Songs with rubato timing, ambient pads, or very sparse percussion may produce less precise results.

It shows an estimated BPM for reference, but the main output is a timestamped list of individual beats. For a single tempo value, use the Key & BPM Finder.
