BEATZUCKER AUDIO LAB

Detect BPM and musical key online

The detector analyzes rhythm and harmonic profile to return BPM, key, Camelot code and useful half- or double-time alternatives for DJ sets, remixes and production.

No permanent audio storage

A remix needs to match the original tempo.

  1. Try this: Analyze the original and tap along while listening. For a 70 BPM result, check the displayed 140 BPM alternative too.
  2. How to interpret it: Half- and double-time may both be musically plausible. Do not treat an undetermined key as a reliable remix instruction.

How it works

  1. Choose WAV, FLAC, MP3 or AIFF
  2. Analyze rhythm and chroma profile
  3. Review tempo alternatives and compatible keys

Frequently asked questions

How accurate is BPM detection?

Tracks with a clear steady beat are usually detected reliably. Breakbeats, tempo changes and ambient material may produce plausible half- or double-time alternatives.

What is Camelot notation?

The Camelot wheel organizes musical keys for easier harmonic mixing and DJ transitions.

Are tracks stored?

Files are processed for analysis and removed from temporary storage afterwards.
