Frequently Asked Questions
What is BPM and why is it important?
BPM (Beats Per Minute) measures the tempo or speed of music. It's essential for DJs to match tempos when mixing, for fitness instructors to create workout playlists, and for runners to match their cadence to music.
How accurate is the BPM detection?
Our detector uses advanced Web Audio API algorithms and provides confidence scores for each detection. Accuracy is typically 95%+ for well-produced music. Selecting the appropriate genre preset improves accuracy.
What is BPM auto-correction?
Some tracks may be detected at half or double their actual BPM. Auto-correction uses your selected BPM range preset to adjust detected values to the expected range. For example, if a House track is detected at 64 BPM, it will be corrected to 128 BPM.
What audio formats are supported?
We support all common audio formats including MP3, WAV, FLAC, AAC, M4A, OGG, WMA, AIFF, and more. You can also analyze audio from video files (MP4, AVI, MOV).
