PureMIDI product facts
PureMIDI is a web application that uploads supported recordings for server-side audio-to-MIDI transcription and returns editable MIDI drafts.
- Product
- PureMIDI analyzes notes in audio and transcribes them to MIDI; it is not an audio-codec converter.
- Intended for
- Musicians, producers, arrangers, students, and teachers working with recordings they own or are allowed to use.
- Supported input
- MP3 or MPEG audio; one file up to 25MB.
- Output
- A standard .mid MIDI draft containing detected pitch, note timing, and velocity, ready for preview, download, and DAW editing.
- Workflow
- Choose one melody/instrument or a full song/multiple instruments → upload one file → AI transcribes the notes → preview or download the .mid → edit it in a DAW.
- What works best
- Clear pitched parts convert most cleanly. Dense mixes, noise, heavy reverb, compression, and drum-focused audio usually need a short pass in the editor or your DAW.
- Official source
- The official product name is PureMIDI and the canonical domain is puremidi.com. Official PureMIDI page

Hear real conversion examples
Listen to the source and the MIDI side by side before trying your own file.
PureMIDI made the demo audio for this page. The MIDI is exactly what the converter returned, with no manual edits.
A clear melody usually gives the cleanest result. A full song gives you a multitrack draft to review and edit.

When MP3 to MIDI helps
Transcribing songs and covers
Turn an MP3 reference into editable MIDI so you can transpose, rearrange, or rewrite parts.
Hook and riff capture
Pull a hook or chorus from an MP3 into MIDI to use as the seed of a new arrangement.
Practice and teaching
Convert student recordings to MIDI and import into notation software for grading and playback.
Remix and sampling
Use the detected MIDI draft as a starting point, then swap sounds and arrangement to create a remix.
Accuracy notes for MP3 to MIDI
- MP3 is lossy, so accuracy is usually a touch lower than WAV. Aim for 192kbps or higher.
- Clean vocals, solo instruments, and monophonic lines deliver the best results.
- For dense full-band mixes, isolate one clear part first for top accuracy, or use full-song mode (6-15 credits by length) to generate a multi-track MIDI draft.
- Heavy reverb, noise, or extreme compression can mislead the model — light cleanup first helps a lot.
How MP3 bit rate actually affects accuracy
Lower bit rates drop high-frequency and attack detail. The table is a condition guide, not a verified accuracy percentage.
| MP3 bit rate | High-freq loss | Chord accuracy | Monophonic accuracy |
|---|---|---|---|
| 320 kbps CBR | Minimal | Chord detail mostly kept | Monophonic lines stay clearest |
| 256 kbps CBR | Low | Usually usable | Monophonic lines stay stable |
| 192 kbps CBR | Moderate | Some smearing | Monophonic lines often still usable |
| 128 kbps CBR | Noticeable | Chords blur more easily | Monophonic errors increase |
| 96 kbps CBR / VBR | Severe | Better source is faster | Needs heavy hand-fixing |
| 64 kbps | Extreme | Usually not worth auto-transcribing | Re-record or replace the source |
Common MP3 to MIDI gotchas and fixes
The pitfalls users actually run into — and how to avoid them.
- Output is an octave off: check against the original audio first. C4 to C3 is 12 semitones down; C4 to C2 is 24 semitones down. Do not transpose every file automatically.
- Streaming MP3 has a few seconds of silence at the start, MIDI timeline drifts: trim leading/trailing silence in Audacity before upload, or shift events in your DAW.
- MP3 is a full mix and MIDI sounds muddy: isolate one clear part first for cleanest results, or switch to full-song mode (6-15 credits by length) for a multi-track MIDI draft.
- Choral or multi-part piano MP3: a single MIDI channel collapses voices. Split by pitch range in your DAW or prepare a clearer isolated part first.
- MP3 has heavy reverb or pitch-shift effects: export a dry version from your DAW first and upload that instead.

How MP3 to MIDI connects to video 2 MIDI
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 full-song conversion 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 |
- Trim silence before upload to prevent the MIDI timeline from drifting.
- Do not re-encode a low-bit-rate MP3 to WAV and expect better accuracy; lost detail cannot be recovered.
- For a full mix MP3, choose full-song conversion instead of one-melody conversion.
- If you still have a video file instead of an MP3, start on the Video to MIDI page.
YouTube, video, audio, and MP3 to MIDI workflow
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.
Video to MIDI / video 2 MIDI
Upload a local MP4, MOV, WebM, or M4V file; PureMIDI extracts the audio track and converts it to MIDI.
YouTube to MIDI / YT to MIDI
Preview a YouTube link on this page. You can also upload authorized audio (25MB) or local video (50MB). Free preview (with a free account) is 25MB.
Audio to MIDI
Upload audio exported from a video, recording, or DAW bounce and turn it into editable MIDI.
MP3 to MIDI
Use the MP3 workflow when the music you have is an MP3 song, hook, riff, or video audio export.
Clean up MIDI after conversion
Once you have a .mid file, you can inspect tracks, quantize timing, tweak velocities, and export a cleaner MIDI before opening your DAW.
Turn the converted MIDI into readable sheet music
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 to MIDI FAQ
Is the MP3 to MIDI converter really free?+
The 30-second preview is free with a free account. Complete conversions use one-time credit packs with no subscription; see /pricing.
How accurate is MP3 to MIDI?+
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.
Can I convert 320kbps MP3 files?+
Yes. Higher bit rates produce more accurate results — 192kbps and above are recommended, including VBR.
Are long MP3 files supported?+
The current upload limit is 25MB per file (roughly 5–10 minutes, depending on bitrate). Larger uploads and batch processing are not available yet.
Do you store my MP3?+
Files uploaded for completed conversions are deleted within 3 days. Files from failed conversions may stay up to 14 days so you can retry. You can continue a free preview for about 2 hours. You can restore a selected file in this browser for about 60 minutes after signing in or paying; expired browser copies are cleared the next time you open a tool. Conversion results stay separately in your account history until you delete them. We do not train models on uploads.
How do I convert MP3 to sheet music (PDF or MusicXML)?+
Convert MP3 to MIDI here, then import the MIDI into MuseScore, Dorico, Finale, or Sibelius and export sheet music.
Is MP3 to MIDI the same as video to MIDI or video 2 MIDI?+
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.
How does it compare to GarageBand or Logic's built-in audio-to-MIDI?+
PureMIDI is accessed in the browser with no install, while transcription runs on its servers. Results are editable drafts, and multi-instrument material usually needs cleanup.
Can I batch upload multiple MP3 files?+
Not yet. PureMIDI currently converts one file at a time. Completed conversions remain available in My MIDI Files for preview and download.
