Frequently Asked Questions
View All FAQsHow does the tool detect embedded tempo tags?
If your MP3, FLAC, WAV, or M4A file has an embedded ID3 TBPM tag, Vorbis comment, iTunes tmpo atom, or ACID chunk, the detector extracts the exact 100% author-defined tempo in under 1 millisecond.
What if my audio file has no embedded tempo metadata?
The detector runs a 2nd-order multi-band IIR biquad filter bank, spectral flux onset novelty curve calculation, harmonic comb filter autocorrelation, and sub-BPM parabolic interpolation for acoustic analysis.
Is my music file uploaded to a server during BPM detection?
No. All audio tag extraction, decoding, multi-band digital filtering, and autocorrelation analysis run 100% locally in your browser using the Web Audio API. Your files never leave your device.
What audio formats are supported?
