Conversion mode
What is in this file?
Solo and stem audio can get a free 30-second Quick Melody preview before sign-in.
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: MP3 / WAV / M4A / FLAC / OGG / WEBM / AAC. 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.
Drag and drop or pick a local file up to 12MB. We only keep it long enough to run the conversion.
The AI engine detects each note's pitch, on/off times, and velocity, producing editable MIDI notes.
Get a clean .mid in seconds and drop it into Logic, Ableton, FL Studio, Cubase, or any DAW.
Capture a clear line or solo part as a MIDI draft so you can rewrite, transpose, or arrange it.
Hum a line or play a riff, get an editable MIDI starting point in seconds.
Convert student recordings into MIDI for notation, playback comparison, and grading.
Use the detected MIDI draft as a starting point, then swap sounds and rebuild it in a new style.
PureMIDI offers two conversion modes. Picking the right one avoids wasted credits and gets you a better MIDI draft on the first try.
| Single-pitch (1 credit) | Full-song / Pro Song (6-15 credits) | |
|---|---|---|
| Engine | Basic Pitch | MT3 |
| Best for | Solo vocal, guitar, bass, or any monophonic line | Full mixes, polyphonic piano, multi-instrument tracks |
| Output | 1-track .mid with pitch + timing | Multi-track .mid (melody, bass, chords, drums, etc.) |
| When to choose | You have a clean, isolated part | You have a mixed recording and want all parts at once |
| DAW built-in | PureMIDI | |
|---|---|---|
| Monophonic clip in session | Fastest — no upload needed | Works, but upload adds a step |
| Polyphonic / chords | Limited or unavailable | Supported via full-song mode (MT3) |
| Full-song multi-track | Not available | One upload → melody, bass, chords, drums |
| No DAW installed | Not available | Runs in any browser, zero install |
| Cross-DAW workflow | Locked to one DAW | Standard .mid opens everywhere |
Format choice has a big impact on MIDI accuracy. Here's how the common formats stack up in practice.
| Format | Compression | Best for | Accuracy |
|---|---|---|---|
| WAV / AIFF | Lossless | Studio stems, solo parts | ★★★★★ |
| FLAC | Lossless compressed | Archival performance recordings | ★★★★★ |
| MP3 320 kbps | Lossy | Album-quality commercial audio | ★★★★ |
| MP3 192 kbps | Lossy | Streaming exports | ★★★ |
| MP3 128 kbps | Lossy | Old recordings, voice memos | ★★ |
| M4A (AAC) 256 kbps | Lossy | iOS recordings, Apple Music | ★★★★ |
| OGG Vorbis | Lossy | Games and open-source exports | ★★★ |
When you can pick, always upload lossless WAV or FLAC. If MP3 is all you have, aim for 192 kbps or higher. Re-encoding low-bit-rate MP3 to WAV before upload doesn't recover lost quality.
For the best results, use the page tuned to your instrument — each has workflow tips, DAW-specific steps, and FAQ for that context.
Electric, acoustic, and DI guitar recordings — includes tips for strumming vs single-note lines.
Solo piano recordings — polyphonic-friendly, optimized for piano timbre.
Bounce → upload → drag back workflow for Logic Pro X / 11 users.
Export Audio/Video → upload → drag back for Ableton Live 11, 12, Lite.

Beyond audio conversion, PureMIDI offers additional MIDI creation and editing tools.
Choose the right page and mode before you upload. That avoids wasted credits and gives you a more useful MIDI draft than blindly uploading a dense mix.
| Source | Best page | Best mode | Why |
|---|---|---|---|
| Solo vocal / lead melody | Audio to MIDI | Quick Melody | 1 credit, best for single-pitch material |
| Full song / mixed track | Audio to MIDI | Pro Song | MT3 can produce a multi-track MIDI draft with melody, bass, chords, and drums |
| Audio exported from video | Audio to MIDI | Depends on complexity | Uploading audio is usually faster and cleaner than uploading a large video |
| Local MP4 / MOV video | Video to MIDI | Pro Song or Quick Melody | Use the video page if you have not extracted the audio yet |
| MP3 file | MP3 to MIDI | Depends on complexity | The MP3 page explains bit rate, compression, and common conversion fixes |
MIDI stores notes, not the original sound. After conversion, pick instruments, quantize timing, and clean up false notes in Logic, Ableton, FL Studio, Cubase, GarageBand, or PureMIDI's online editor.
These searches describe the same practical job: turn music from a video or audio file into an editable .mid. PureMIDI converts the audio track, not the video pixels, and it does not download from YouTube.
Upload a local MP4, MOV, WebM, or M4V file; PureMIDI extracts the audio track and converts it to MIDI.
Preview a YouTube link, confirm rights, then continue to upload authorized audio.
Upload audio exported from a video, recording, or DAW bounce and turn it into editable MIDI.
Use the MP3 workflow when the music you have is an MP3 song, hook, riff, or video audio export.
Video to MIDI and video 2 MIDI usually mean converting the video's audio track into MIDI. Export or obtain an audio file you own or are licensed to use, then upload it to PureMIDI.
Once you have a .mid file, you can inspect tracks, quantize timing, tweak velocities, and export a cleaner MIDI before opening your DAW.
Audio conversion creates MIDI first. When you need notation, open the downloaded .mid as staff notation, review playback, transpose, and export MusicXML or a PDF draft.

MP3, WAV, M4A, FLAC, OGG, WEBM, and AAC. The current limit is 12MB per file for every account.
Yes, when you upload the video's audio track rather than the video file itself. Export or obtain an MP3, WAV, M4A, or FLAC file you own or are licensed to use, then convert that audio to MIDI here.
The single-pitch engine detects pitch and timing, not separately bass/chords/drums. For mixed tracks, full-song mode (6-15 credits by length) uses MT3 to generate one multi-track MIDI draft covering melody, bass, chords, drums, and other parts.
We only store files long enough to run the conversion, then clean them up. We never use your audio to train models.
Dense mixes, heavy effects, and unusual timbres degrade detection in single-pitch mode. Either isolate one clear part first, or switch to full-song mode (6-15 credits by length) for a multi-track MIDI draft.
Yes. The output is a standard .mid file that opens in every major DAW — Ableton, Logic, FL Studio, Cubase, Reaper, GarageBand, and more.
The current upload limit is 12MB per file (roughly 5–10 minutes, depending on format and bitrate). PureMIDI converts one file at a time; larger uploads and batch conversion are not available yet.
Single-pitch mode (1 credit) uses Basic Pitch to detect one melodic line — ideal for solo vocals, guitar, or bass. Full-song mode (6-15 credits by length) uses MT3 to transcribe an entire mix into a multi-track MIDI file with separate channels for melody, bass, chords, and drums.
DAW built-in tools (Logic Flex Pitch, Ableton Convert Audio to MIDI) are quick for monophonic clips already in your session. PureMIDI adds value for polyphonic or full-song conversion, when you don't have a DAW installed, or when you want multi-track output from a single upload.
Yes — and we have dedicated pages with instrument-specific tips: Guitar to MIDI for electric/acoustic recordings, and Piano to MIDI optimized for polyphonic piano timbre. Both use the same AI engine but guide you through the best workflow for that instrument.
