Frequently Asked Questions
- How accurate is the BPM detection?
- The Web Audio API peak detection algorithm is reliable for most modern music with a clear beat. Electronic, pop, and rock tracks detect best. Complex jazz or classical may be less accurate.
- Is my audio uploaded to a server?
- No. The BPM detector runs entirely in your browser using the Web Audio API. Your audio file never leaves your device.
- What formats are supported?
- Any format your browser can decode — typically MP3, WAV, M4A, OGG, and FLAC. Browser support varies.
- What is BPM used for?
- BPM (beats per minute) is used by DJs for mixing, producers for tempo matching, dancers for choreography, and musicians for practice with a metronome.
