How Audio to MIDI Conversion Works
Our AI listens to your audio and transcribes what it hears into MIDI notes.
Audio Analysis
Our AI analyzes the frequency spectrum, detecting individual notes, chords, and rhythmic patterns.
Pitch Detection
Advanced algorithms identify the fundamental pitch of each note, even in complex polyphonic audio.
MIDI Generation
Detected notes are converted to MIDI events with accurate timing, velocity, and duration.
Processing time depends on audio length. A 3-minute song typically takes 15-45 seconds.
What Accuracy Can You Expect?
Audio to MIDI conversion is challenging. Here's what our AI can deliver:
Solo Instruments
90%+Single melody lines, piano solos, or isolated instrument tracks work best.
Simple Arrangements
80-90%Sparse arrangements with clear separation between instruments.
Full Band / Complex
60-80%Dense mixes may lose some detail. Consider separating stems first.
Heavy Distortion
VariableHighly distorted audio is difficult to transcribe accurately.
Audio to MIDI is fundamentally harder than sheet music to MIDI. Our tool gives you a solid starting point, but some manual editing may be needed.
Tips for Best Results
Follow these tips to get the most accurate MIDI transcription:
Use Clean Audio
Audio without background noise or effects converts more accurately.
Isolate Instruments
If possible, use stems or isolated tracks. Try our Vocal Remover to separate instruments.
Choose High Quality
Higher bitrate and sample rate audio files produce better results.
Simple is Better
Single instrument recordings convert more accurately than full mixes.

Workflow examples
A place in your music workflow.
I start with a short piano recording and inspect the MIDI in my music software. After correcting the notes, I can build a lesson around that phrase.
Piano exercisesI work from one clear melodic idea at a time. Once I have checked the converted line by ear, I develop the arrangement in my own software.
Melody arrangingI compare the converted notes with what I hear in the recording. Where they differ, I work through the phrase slowly instead of assuming the MIDI is right.
Ear trainingTurning a recorded melody into a MIDI draft suits the way I write. I listen back to the source while reshaping the phrase in my music software.
Melody writingThe MIDI is a starting point for my DAW session. I keep the recording on another track while I adjust the notes and try a different instrument sound.
Production sketchA little recorded phrase is often all I have at the start of a song. An editable MIDI sketch gives me something to revise without losing the original idea.
Recorded ideasI use a simple guitar phrase as the source, then inspect the result in my DAW. Bends and timing still need my attention before I use the part.
Guitar phrasesI use short recordings for transcription exercises. Reviewing a MIDI draft against the audio gives me material for discussing pitch and rhythm with students.
