Built for producers who move fast.
Every feature designed to get you from audio to MIDI in seconds, not minutes. No friction, no fees.
Neural Audio Extraction
Spotify's Basic Pitch model runs directly in your browser. It detects notes, chords, pitch bends, and micro-timing with industry-leading accuracy.
Instant Processing
No upload queues, no server wait times. Your audio is decoded and transcribed locally using WebGL-accelerated inference. Most files finish in under 10 seconds.
Works with your DAW
Download standard .mid files that open directly in Ableton, FL Studio, Logic Pro, Cubase, and every other DAW that supports MIDI import.
Your audio stays on your device
All processing happens client-side using WebAssembly. Your audio files are never uploaded to any server. No account required, no tracking of your content.
Multi-Format Support
Upload MP3, WAV, FLAC, or OGG files up to 50MB. The decoder handles all common audio formats automatically — no conversion needed before uploading.
MIDI Preview Before Download
See exactly what was transcribed with an interactive piano roll visualization. Hover over notes to see pitch, timing, and velocity before you download.
