PureMIDI uses AI to detect pitch, timing, and velocity, exporting a standard MIDI file you can open in any DAW. Sign up to claim 2 free trial credits — no subscription. Treat the result as an editable MIDI draft.
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: MP3 at 192 kbps or higher, with the hook, riff, vocal guide, or song section you actually need.
Avoid: Long silence, noisy phone audio, heavy reverb, drum-only loops, or low-bitrate/full mixes in Quick Melody.

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.
Fixed benchmark v1 · verified July 15, 2026
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 fixed lead melody re-encoded as MP3 and run through the live MP3-to-MIDI path without manual cleanup.

The source clips are PureMIDI-owned synthetic demos; the MIDI files are raw provider outputs, not hand-corrected.

The AI engine analyzes pitch, on/off times, and velocity to create editable MIDI notes.
Receive a standard .mid file and drop it into Logic, Ableton, FL Studio, Cubase, Reaper, or GarageBand.
Turn an MP3 reference into editable MIDI so you can transpose, rearrange, or rewrite parts.
Pull a hook or chorus from an MP3 into MIDI to use as the seed of a new arrangement.
Convert student recordings to MIDI and import into notation software for grading and playback.
Use the detected MIDI draft as a starting point, then swap sounds and arrangement to create a remix.
Numbers from our internal test on a piano performance, compared against the WAV ground truth.
| MP3 bit rate | High-freq loss | Chord accuracy | Monophonic accuracy |
|---|---|---|---|
| 320 kbps CBR | Minimal | 92% | 97% |
| 256 kbps CBR | Low | 89% | 96% |
| 192 kbps CBR | Moderate | 82% | 93% |
| 128 kbps CBR | Noticeable | 71% | 86% |
| 96 kbps CBR / VBR | Severe | 58% | 76% |
| 64 kbps | Extreme | <50% | <70% |
If your only source is below 96 kbps MP3 (early phone recordings, phone-call captures, old radio rips), error rates climb so high that re-performing the part is faster. Better to upload a higher-quality source, or hand-fix the MIDI in your DAW.
The pitfalls users actually run into — and how to avoid them.
Workflow articles to help you get more out of your MP3-to-MIDI output.
Many video 2 MIDI workflows end with an MP3 exported from a video. This page is the right path when the music source you actually have is an MP3 file.
| Search intent | File to upload | Recommendation |
|---|---|---|
| MP3 to MIDI | Local MP3 | Use 192kbps or higher when possible |
| MP3 song to MIDI | Full song MP3 | Use Pro Song for a multi-track MIDI draft |
| video 2 MIDI | MP3 exported from video | Confirm rights, then upload the MP3 audio track |
| YouTube to MIDI | Authorized MP3 from a legal source | PureMIDI does not download YouTube; it converts audio you upload |
| MP3 to sheet music | Clear melody MP3 | Convert to MIDI, then open in MuseScore, Dorico, or Sibelius |
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.

Best for solo instruments, clean vocals, and monophonic lines. For full-band mixes, prepare one clear part first, or use full-song mode (6-15 credits by length) for a multi-track MIDI draft.
Yes. Higher bit rates produce more accurate results — 192kbps and above are recommended, including VBR.
The current upload limit is 12MB per file (roughly 5–10 minutes, depending on bitrate). Larger uploads and batch processing are not available yet.
We only keep files while we run the conversion, then clean them up. We never use your audio to train models.
Convert MP3 to MIDI here, then import the MIDI into MuseScore, Dorico, Finale, or Sibelius and export sheet music.
If the video's audio track is an MP3, yes — use this page. PureMIDI converts authorized audio, not video pixels, so export or obtain an MP3 you own or are licensed to use and upload it here.
