AI online tool · 2 free trial credits on signup · turn lossless WAV into editable .mid
Upload a WAV up to 12MB, choose Quick Melody for one clear part or Pro Song for a mixed arrangement, then download an editable .mid file. Because WAV is lossless, it preserves more pitch and timing detail than a compressed MP3 input.
Choose a supported file, then convert it to an editable MIDI draft.
Best: Clean solo melody, vocal guide, guitar riff, bass line, piano phrase, or instrument stem.
Avoid: Long silence, noisy phone audio, heavy reverb, drum-only loops, or low-bitrate/full mixes in Quick Melody.

Formats: WAV / AIFF / FLAC. Max 12MB.
PureMIDI is a browser-based AI audio-to-MIDI transcription application that turns supported recordings into editable MIDI drafts.
These samples were generated through the same production conversion paths users get: Basic Pitch for single-part audio and MT3 for full-song mode.

Each frozen input is submitted through the production route shown below. The downloadable MIDI is the unedited provider result; duration, track count, note count, byte size, and SHA-256 are measured after download.
A parseable MIDI with notes is a delivery check, not an accuracy claim. Listen to source and MIDI together: isolated melody is the strongest case; mixed music remains an editable draft.

The source clips are PureMIDI-owned synthetic demos; the MIDI files are raw provider outputs, not hand-corrected.
Drop in a 16-bit or 24-bit WAV up to 12MB.
The model analyzes onsets, pitches, and velocities, then writes editable MIDI notes.
Open the resulting .mid in Pro Tools, Logic, Cubase, Ableton, or any DAW for further editing.
Turn pitch-clear vocal, guitar, piano, or bass stems into editable MIDI drafts.
Convert live or rehearsal WAV recordings to MIDI for review and re-arrangement.
Turn sample loop WAVs into MIDI and remap them to your own sounds.
Convert high-quality performance WAVs to MIDI for notation, comparison, and study.
If you have stem WAVs from a Pro Tools / Logic / Cubase / Reaper session, this is the recommended pipeline.
PureMIDI turns detected pitch and timing into a MIDI draft and is most reliable on monophonic vocals and solo instruments. For complex mixes, you can pre-separate stems for best quality, or use full-song mode (6-15 credits by length) to generate a multi-track MIDI draft. Percussion may still need manual cleanup downstream.
Different stems benefit from different preprocessing. The current model is strongest on pitch-clear parts.
| Stem type | Preprocessing | MIDI cleanup | Suggested instrument |
|---|---|---|---|
| Lead vocal | Denoise + de-reverb | Check note lengths and slides | Piano or vocal synth |
| Bass | Preserve the low fundamental | Check octave and short notes | Sub bass / electric bass |
| Lead piano / guitar | Light compression | Clean overlapping notes | Acoustic piano / EP |
| String pad | Reduce reverb | Split by pitch range | Strings / synth pad |
| Choir | De-reverb | Manual voice cleanup | Choir / voice patch |
| Drums / percussion | Not recommended as the primary input | Use manual or dedicated drum transcription | Map GM drums separately |
Choose the conversion path that matches your source. These pages separate general audio, compressed MP3, YouTube/YT workflows, and local MP4/video files so each search intent has one clear owner.
Best default for WAV, M4A, FLAC, recordings, stems, and authorized audio exported from video.
Use the MP3-specific page when your source is compressed MP3 and you need bitrate or retry guidance.
Preview a link, confirm rights, then upload audio you own or are licensed to use for MIDI conversion.
Upload a local MP4, MOV, WebM, or M4V and convert its audio track directly to MIDI.
Once you have a .mid file, you can inspect tracks, quantize timing, tweak velocities, and export a cleaner MIDI before opening your DAW.
Usually yes. WAV preserves the full audio signal so the AI extracts pitch and timing more reliably.
Yes. 24-bit / 48kHz studio WAV files work directly.
The current upload limit is 12MB per file for every account. Larger uploads and batch conversion are not available yet.
The converter handles one file at a time. Split a mix into pitch-clear parts and convert each independently for best quality, or upload the mix to full-song mode (6-15 credits by length) for a multi-track MIDI draft. Drums and percussion may still need manual cleanup.
Try exporting a drier version. Reverb smears note onsets and lowers detection accuracy.
Yes. AIFF is the same family of lossless formats and is supported.
Quantize lightly, tweak velocities, and assign instruments in your DAW for the most musical playback.
Yes. Convert lossless recordings to MIDI, then import into Sibelius, Dorico, or MuseScore for pitch, rhythm, and expression analysis.
Convert audio files or audio exported from video into editable MIDI drafts.
Convert MP3 songs or MP3 audio exported from video into editable MIDI.
Preview YouTube/YT links, then upload authorized audio for MIDI conversion.
