Audio Analysis BPM Detector

Estimates the tempo (BPM) of an audio signal using onset detection and inter-onset interval analysis with harmonic voting. Outputs the detected BPM value and a synchronized beat trigger.

Best suited for rhythmic material (drums, percussion, electronic music). Accuracy improves after a few beats have been detected. The detector uses a stability lock mechanism — it waits for several consistent estimates before updating the BPM output, which avoids erratic jumps.
