About MP3 File to MIDI

Why we built this audio to midi converter

As independent developers and music enthusiasts, we were frustrated by the lack of accessible tools to convert an mp3 file to midi. When you search for a midi converter online, you usually run into three major problems:

• High Costs: Most high-quality transcription services hide behind expensive monthly subscriptions.
• Privacy Risks: Free tools often require you to upload your personal audio files to mysterious cloud servers, putting your creative work at risk.
• Poor Quality: Many older tools simply don't use modern AI, resulting in messy, uneditable MIDI files.

Our Solution

We decided to build a better way. By leveraging modern WebAssembly and local AI models (powered by Spotify's open-source Basic Pitch architecture), we created a tool that runs entirely in your web browser.

This means when you use our tool to convert audio to midi, your computer's own CPU handles the heavy lifting. Your MP3 or WAV files are never uploaded to our servers. This completely eliminates privacy concerns while keeping our server costs at zero—which is why we can offer this mp3 to midi converter to you completely for free.

Who is this for?

Whether you are a music producer looking to remix a sample, a songwriter wanting to digitize a vocal melody, or a student trying to generate sheet music from a recording, this tool was built to save you time and money.
