BPM Detector FAQ
Which files can I analyze?
The detector supports common browser-readable audio files such as MP3, WAV, M4A, AAC, FLAC, and OGG.
How accurate is BPM detection?
It is an estimate. Tracks with clear drums or steady rhythm usually produce the best results.
Is my audio uploaded?
No. The BPM detector analyzes the file locally in your browser.
Can it detect tempo changes within a track?
The detector returns a single dominant BPM. If a track has multiple tempos or rubato sections, the reported value reflects the strongest steady section, not the changes.
Does it work with live recordings or acoustic music?
Yes, but accuracy drops when the rhythm is loose or there are no percussive transients. Cleanly recorded loops and drum-led songs analyze most reliably.
How long does BPM detection take?
Most tracks under five minutes finish analysis in a few seconds. Larger files or slower devices may take a bit longer because the analysis runs locally on your CPU.
Can I use the detected BPM in my DAW or DJ software?
Yes. Copy the BPM value into your DAW project tempo or DJ software so that quantization, looping, sync, and beat-matching line up correctly with the track.
What if the track feels half-time or double-time?
Energy-based detectors sometimes report a value that is exactly half or double the perceived tempo. If the reading feels off, multiply or divide by two and trust your ear.
