Audio Tools: BPM Detection, Stems & Music Analysis

Yes; every tool is free. No subscriptions, no per-file charges.

Completely. Audio files are processed in your browser using WebAssembly or WebGPU. Nothing is uploaded to any server. Your music stays on your device.

For music with a clear, consistent beat, the detector is typically accurate within 1-2 BPM. Complex tracks with tempo changes, polyrhythms, or sparse arrangements may produce less reliable readings. Always verify against your DAW's built-in counter.

MP3, WAV, OGG, and FLAC are supported by most tools. The exact list depends on your browser's audio decoding capabilities. Chrome supports the widest range of formats.

It depends on the source material. Clean studio recordings separate better than live recordings or heavily compressed MP3s. The AI model is state-of-the-art for browser-based processing, but professional studio tools with GPU acceleration will still outperform it on difficult material.

The tool is just a separator; copyright belongs to the original rights holders. Using separated stems from copyrighted music without permission is a legal issue, not a technical one. For your own original music, you can do whatever you want with the stems.

Audio AI models are computationally intensive. The speed depends on your CPU and GPU. Closing other browser tabs frees up resources. If processing is too slow, try a shorter audio clip first to test the result before committing to a full track.
