PureMIDI

PureMIDI is an AI tool that turns recorded audio into an editable MIDI draft in your browser. PureMIDI converts uploaded audio into an editable .mid draft, with a cheap single melody mode and a multi track full song mode. Browser based, DAW agnostic, best on clean pitched material.

PureMIDI is a browser based audio to MIDI converter. It accepts an MP3, WAV, M4A, FLAC, OGG, WEBM or AAC file up to 25MB, analyzes the notes, and returns a standard .mid draft carrying detected pitch, note timing and velocity. The result is meant to be pulled into a DAW for arrangement and sound design, not treated as a finished transcription. Everything runs on PureMIDI servers, so no plugin install and no specific DAW are required. The tool separates two jobs. One melody or instrument mode costs a single credit and is built for a solo vocal line, a guitar riff, a bass part or any monophonic phrase, returning a single track. Full song or multiple instruments mode costs between 6 and 15 credits depending on length and produces a multi track draft with melody, bass, chord and drum parts pulled from a mix. Choosing the wrong mode is the most common way to waste credits, so the site includes a comparison of the two. In practice the workflow is upload, choose the mode, preview, then download the .mid and quantize or fix velocities in your DAW. PureMIDI also hosts a browser piano roll editor for cleanup before export, and a MIDI to sheet music path for notation. Instrument specific pages cover guitar, piano, Logic Pro, Ableton, MP3, WAV, video and YouTube workflows. A free account gives a 30 second preview of any conversion, which is a sensible way to judge accuracy on a specific recording before buying credits. Accuracy is the honest constraint. Clean monophonic material converts best. Dense mixes, heavy reverb, compression and drum heavy audio degrade detection, and the site says so directly. Built in DAW tools are faster for a clip already sitting in a session, so PureMIDI earns its place on polyphonic material, multi track output from one upload, or work done without a DAW installed. The studio and education use cases hold up; anything expecting a perfect chart from a noisy live recording will not.
