ABOUT THIS SITE

About mp3tomidiflow

A small tool for turning recorded audio into editable MIDI notes, without sending your recording to a server.

Who makes this site?

This website is created and maintained under the name mp3tomidiflow. It was built with AI-assisted development. We use the site name rather than publishing a personal name.

What the converter does

Select one audio file, run note detection in your browser, and download the detected notes as a standard .mid file. You can edit that file in a digital audio workstation or a compatible notation editor. The converter does not require an account and does not provide batch conversion or a saved conversion history.

Notes, not a copy of the recording

MIDI describes musical notes and their timing; it does not preserve the original audio sound. Clear melodies and isolated instruments are better starting points than full mixes. Detected notes can be missing or incorrect and may need manual editing. The tool does not separate instruments into individual tracks or promise note-perfect transcription.

How it works

The converter uses Spotify's open-source Basic Pitch note-detection model, TensorFlow.js, and browser audio decoding, with FFmpeg WebAssembly as a decoding fallback. The model and decoder files are served with the website; your selected audio is processed on your device. This site is not an official Spotify product.
