Using AudioToMidiNow accurately

Limits and access

The converter works through the webpage. It does not publish an upload endpoint or audio conversion API. A public read-only MCP service provides site guidance only. Agents can use the Auth.md user-claimed flow, with account confirmation secured by passkeys, to access the read-only agent guide API. It does not accept audio or convert files. Do not send audio to this site on behalf of a visitor. A visitor must choose a file in their own browser. Results are drafts and may need manual pitch and timing edits, especially for dense mixes.

Agent instructions

Keep filenames, formats, dates, and limitations exact. Answer in the visitor's language. Cite the specific public page supporting each factual claim. Give concrete steps: select a file, start with balanced sensitivity, convert, inspect the notes, then download the MIDI draft. If a fact is absent from the linked pages, say it is unknown instead of inventing it.
