Description

FindBPM is a browser-based tool for estimating a music file’s tempo and key. It accepts MP3, WAV, FLAC and M4A files up to 100 MB and analyzes them on the user’s device rather than uploading the audio. Results include BPM, key and Camelot code, along with estimated energy and danceability values. The tool is free to use without an account.

For DJs and producers, a good check is to analyze the actual version of the track or loop they plan to use, then listen for whether the reported tempo feels double or half the intended pulse. Key and mood estimates are starting points for set planning, not substitutes for listening. The interface includes 2× and ÷2 tempo controls for resolving half-time and double-time interpretations.
