Convert a clear MP3, WAV, M4A, FLAC, OGG, AAC, or AIFF melody into editable MIDI notes, preview the result, and export a standard .mid file.
Drop a solo melody, vocal line, or bass recording here, or import from:
An audio to MIDI converter analyzes pitch and timing in a recording, then represents the detected performance as editable MIDI note events instead of another audio waveform.
This browser tool is optimized for monophonic material: a clear vocal melody, hummed tune, bass line, whistle, or solo instrument playing one main note at a time.
Stable pitches become MIDI notes with a start time, duration, velocity, and confidence value.
Inspect the detected melody across time and review individual note values before creating the file.
Set tempo, quantize note timing, transpose the melody, and store an instrument program in the export.
Create a format 0 MIDI file for a DAW, notation editor, sequencer, mobile music app, or hardware workflow.
A clean source with one note at a time produces the most useful MIDI draft.
Upload MP3, WAV, M4A, FLAC, OGG, AAC, AIFF, WebM, or supported MP4 audio, or record a clear melody.
Use Clean Recording for a strong isolated source, Balanced for most files, or Quiet Details for softer notes.
Detect the melody, inspect the piano roll, and check note pitch, timing, length, and velocity.
Adjust tempo, quantization, transpose, and instrument, preview the result, then create the .mid file.
File format affects source quality and compatibility, while the clarity of the musical line has the greatest effect on note detection.
MP3 works well for a clear vocal, bass, whistle, or solo instrument, although lossy compression can soften attacks and add artifacts.
WAV avoids lossy compression and is a strong choice for close, dry recordings captured from a microphone, instrument, or DAW.
These common audio formats can also be decoded when they contain a browser-supported audio stream.
Record a melody from the microphone or import eligible media you own or have permission to use.
MIDI is useful when a recorded idea needs to become editable musical data.
Sing or hum an idea, turn it into notes, and assign a synth, piano, or orchestral sound in a DAW.
Convert a clean monophonic part into notes that can be corrected, doubled, rearranged, or used as a transcription draft.
Import the MIDI file into notation software as a starting point for a lead sheet, exercise, or written melody.
Use the detected notes to trigger another virtual instrument while keeping the main pitch and timing contour.
Transpose the detected phrase and quantize loose note timing before continuing in a MIDI editor.
Turn a short solo phrase into MIDI that can be slowed, looped, transposed, or reassigned inside a practice app.
Audio stores recorded sound; MIDI stores instructions that another instrument or application uses to produce sound.
| Audio recording | MIDI file | |
|---|---|---|
| Stores | A waveform containing the original sound | Note pitch, timing, duration, velocity, and instrument data |
| Editability | Usually edited as a continuous signal | Notes can be moved, shortened, transposed, deleted, or reassigned |
| Sound | Keeps the recorded voice or instrument | Uses the sound selected in the receiving app or instrument |
| Best use | Listening, mixing, effects, and mastering | Arrangement, notation, virtual instruments, and note-level editing |
Converting audio to MIDI detects musical events; it does not place the original recording inside the MIDI file.
Yes. Use a clear MP3 with one main melody at a time, then review the detected notes before exporting the MIDI file.
Yes. A dry, clean WAV recording is a strong source because it avoids additional lossy compression, but it still works best with one main note at a time.
Yes. Record or upload a clear vocal melody with limited room noise, backing music, harmony, and reverb.
No. This converter detects a monophonic melody, not drums, chords, bass, vocals, and multiple instruments as separate tracks.
Accuracy depends on pitch stability, note separation, background noise, reverb, source compression, and whether several pitches overlap.
Quantization moves note starts and lengths to a selected beat grid. It can clean timing but may reduce the expressive timing of the original performance.
Most DAWs, notation editors, MIDI sequencers, mobile music apps, and many hardware workstations can import a standard .mid file.
Files selected from your device are decoded and analyzed in the browser. Link and cloud imports depend on the selected import provider.
Convert MP3, WAV, M4A, FLAC, OGG, AAC, AIFF, WMA, Opus, and AMR, with optional MP4 audio input and ALAC output.
Convert MP4, MOV, AVI, MKV, WEBM, FLV, or WMV entirely in your browser.
Detect monophonic pitch, clean up timing, transpose notes, preview the result, and export a standard MIDI file.
