MIDI Conversion FAQs

How accurate is the MIDI conversion?

Good accuracy for single instruments, especially monophonic melodies. Polyphonic works better with clear recordings.

What instruments work best?

Piano, guitar, bass, vocals, drums. For complex mixes, try stem separation first to isolate instruments.

Can I edit the MIDI afterward?

Yes, the MIDI files work in any DAW - Ableton, FL Studio, Logic, Cubase, etc.

Does it detect chords?

Yes, detects both single notes and chords. Single melodies have higher accuracy than complex chords.

Will it work in my browser?

Music Demixer works best on modern computers with up-to-date web browsers. WebGPU in the latest Chrome, Edge, or Safari gives the best results. Use our compatibility check or visit the full guide to see if your setup is ready.

Audio to MIDI Conversion Online

Convert audio files to MIDI without installing software. Our browser-based converter uses AI to transcribe melodies, chords, and rhythms from MP3, WAV, or any audio format into editable MIDI files for your DAW.

How Audio to MIDI Works

The AI analyzes your audio to detect:

  • Pitch and notes
  • Timing and rhythm
  • Velocity/dynamics
  • Chords (for polyphonic instruments)

Tip: Use "Other Lead" for strings, brass, synths, woodwinds - any melodic instrument that isn't piano, guitar, or bass.

Common Uses for Audio to MIDI

Music Production: Convert recordings to MIDI, then change instruments in your DAW. Turn a piano melody into strings or synths.

Remixing: Extract MIDI from vocals or bass lines to build new tracks. Preserve the original groove while changing the sounds.

Education: Students convert songs to MIDI to study note patterns, slow down passages, or transpose keys. Combine with our sheet music converter for learning.

Arrangement: Test how melodies sound on different instruments. Convert guitar to MIDI and try it on piano or orchestra.

Instrument-Specific MIDI Results

Piano: Polyphonic transcription with chord detection. Works best with clear recordings.

Guitar: Detects bends, slides, and hammer-ons. Single notes work better than complex chords.

Bass: Good low-frequency tracking. Captures groove and ghost notes.

Vocals: Extracts melodies from singing. Filters out speech and non-musical sounds.

Other Lead: Strings, brass, woodwinds, synths. Best for monophonic (single-note) melodies.

Tips for Better MIDI Results

Clean recordings: Studio-quality audio gives better results than live recordings with crowd noise.

Single instruments: Works best with isolated instruments. For full songs, use stem separation first to isolate parts.

MP3 vs WAV: Both work, but uncompressed audio (WAV/FLAC) gives slightly better results than MP3.

Complex mixes: Separate stems first, then convert each stem to MIDI individually for accuracy.

MIDI Compatibility

Works with all DAWs (Ableton, FL Studio, Logic, Cubase, Pro Tools) and notation software (MuseScore, Finale, Sibelius). Standard MIDI format for universal compatibility.

Privacy & Browser Processing

All conversion happens in your browser. Files never leave your device - no uploads, no servers.

Quick Start Guide

  1. Upload your audio file (MP3, WAV, etc.)
  2. Select the instrument type
  3. Wait for processing
  4. Download your MIDI file

For complex songs, use stem separation first to isolate instruments, then convert each to MIDI.
