Fast workflow

  1. Analyze the file. Start with the highest-quality source you have. WAV is ideal, but MP3, M4A, FLAC, OGG, and AAC work across the browser tools.
  2. Check scale notes. Open the matching tool, preview before export, and make one clean move at a time so you can hear what changed.
  3. Tune or transpose. Download a WAV, then keep going inside Rys Up Studio or move to the matching Rys Up plugin when the sketch becomes a real session.

Use the free browser workflow to sketch the move, then finish it with Rys Up plugins inside your DAW.

Frequently Asked Questions

Is this key detector tool free?
Yes. The BPM & Key Finder workflow is free, works in your browser, and does not require a signup or watermark.
Does my audio get uploaded?
Most Rys Up tools process locally in your browser. AI stem separation tools use cloud GPUs because the model is too heavy for normal browsers, and files are deleted after processing.
What should I export?
Export WAV when you plan to keep editing. Starting from WAV gives TikTok, YouTube, your DAW, or another Rys Up tool the cleanest file to compress or process next.
