BPM Finder
Free browser-based BPM detector for audio files, tap tempo and live mic, processing audio locally with no uploads.
What it does
BPM Finder is a free, privacy-first tempo analyzer that detects the beats per minute of songs entirely in the browser. It supports uploaded files (single or batch), manual tap tempo and real-time microphone input, using a CNN-based model with confidence scores and CSV export, and needs no account.
How to use: To use BPM Finder, choose your preferred analysis method: 1. **Single File Analysis**: Upload one audio file (MP3, WAV, FLAC, AAC, OGG, M4A, max 50MB) for instant BPM detection. 2. **Batch Processing**: Upload multiple files simultaneously for efficient analysis of your music library. 3. **Tap Tempo Mode**: Manually tap the rhythm to determine the BPM, useful for live performances or when no audio file is available. After analysis, you can export results by copying them, saving to CSV, or integrating them with your DAW and DJ software.
