About the BPM Detector
The BPM Detector is a free browser-based tool that analyzes any audio file and reports its tempo in beats per minute (BPM). It uses the Web Audio API to decode and process the audio waveform locally — no upload, no server, no sign-in required. This makes it ideal for DJs, producers, and musicians who need a fast, private way to find the tempo of a track before mixing, sampling, or syncing to video.
Instant Analysis
BPM detection typically completes in seconds. No waiting for uploads or server-side processing.
Fully Private
Your audio file is processed entirely in your browser. Nothing is sent to a server.
Wide Genre Support
Works best for electronic, hip-hop, pop, and dance music. Provides a reasonable estimate for most rhythmic genres.
No Software Needed
Works directly in any modern browser — Chrome, Firefox, Safari, or Edge. No plugins or apps to install.
Tap-tempo or complex polyrhythms may show variance. Try re-analysing with adjusted BPM range if the result looks off.

FAQ
Frequently Asked Questions
How accurate is the BPM detection?
The BPM detector is accurate for most rhythmic music genres including electronic, hip-hop, pop, house, and techno. Accuracy may be lower for music with irregular rhythms, live recordings with tempo fluctuations, or classical compositions without a strong beat.
Is my audio file uploaded to detect the BPM?
No. The BPM detection runs entirely in your browser using the Web Audio API. Your audio file never leaves your device.
What audio formats does the BPM detector support?
The tool supports any audio format that your browser can decode, including MP3, WAV, FLAC, OGG, and AAC.
Why does the detected BPM sometimes show a half or double value?
BPM detection algorithms can sometimes report octave errors — returning half (e.g. 75 instead of 150) or double (e.g. 300 instead of 150) the actual tempo. If the result seems wrong, try doubling or halving the number. The tool shows the most likely value but the true BPM may be a multiple of the displayed figure.
Can I use this for DJ sets or mix preparation?
Yes. The BPM detector is a practical tool for checking track tempos before mixing. Knowing the BPM of each track allows you to beatmatch accurately and plan transitions.
Does the tool work on mobile browsers?
Yes, the BPM Detector works on modern mobile browsers that support the Web Audio API, including Chrome for Android and Safari on iOS.
