MP3 to MIDI
What it is
MP3 to MIDI is a web tool that turns audio recordings into standard MIDI files. It runs Spotify's open Basic Pitch transcription model inside the browser, so the audio file stays on the user's device instead of being uploaded. After choosing a preset such as Piano, the user can compare the original audio with a MIDI preview, adjust notes in a piano roll editor and then download the file for use in a DAW or notation program. Beyond MP3, the site offers converters for WAV, M4A, OGG, video files and YouTube links. Conversion is free for clips up to five minutes, while paid credit packs cover additional downloads.

What we like about this converter is how much it does without ever uploading your audio. The transcription model runs in the browser tab, which is a real plus for musicians who do not want unreleased recordings sitting on someone else's server. The preview step is also thoughtful: you can play the original next to the MIDI result and fix wrong notes before you spend a download credit.
- Built on Spotify's Basic Pitch, a well-known open model for note detection
- Presets such as Piano tune sensitivity and note length for cleaner results
- A built-in piano roll lets you correct notes before exporting
- Separate converters cover WAV, M4A, OGG, video files and YouTube links
- Paid credits are permanent rather than tied to a monthly subscription
MP3 to MIDI is best for songwriters, producers and students who want a quick starting point for arranging or learning a part, not a finished score. Our tip: feed it the cleanest source you can, such as a solo piano take or an isolated stem, because single instruments with clear melodies give far more accurate MIDI than a full band mix.
