Description
BPM Finder is a free tool that analyzes a track's tempo and finds the BPM of any song. It offers four analysis modes — single file analysis, batch processing for multiple files, real-time microphone detection, and manual tap tempo — and supports common audio formats including MP3, WAV, FLAC, AAC, OGG, and M4A. It requires no registration and is free to use.

Under the hood, BPM Finder runs a Convolutional Neural Network based on the DeepRhythm architecture, exported to a compact ONNX model that classifies audio into BPM bins using Harmonic Constant-Q Modulation features. Processing is done client-side for privacy, so uploaded audio and analysis data are not stored on servers. The tool also includes a key finder, tempo change without pitch shift, and CSV export for professional workflows and integration. Published benchmarks compare its accuracy against tools like Tunebat across hundreds of tracks.
BPM Finder is aimed at DJs, music producers, session musicians, video editors, fitness playlist builders, and music bloggers who need accurate tempo detection for beatmatching, arrangement, synchronization, or curation. It works in the browser with no software installation.
