Frequently Asked Questions
How do I convert audio to MIDI?
Upload an audio file of a single melody — a hum, whistle, sung line, or a lead instrument. Solmi tracks the pitch over time in your browser and builds a standard MIDI file you can download and open in any DAW. Nothing is uploaded; it all runs on your device.
Can it convert a full song or chords to MIDI?
No — this is a monophonic converter, meaning it transcribes one note at a time. It's great for melodies, vocal lines, basslines, and leads. Full mixes and chords (polyphonic transcription) need much heavier AI models and aren't supported here. For the cleanest result, give it a single, clear voice or instrument.
What audio formats can I upload?
MP3, WAV, M4A, AAC, OGG, and FLAC — any format your browser can decode. The output is a standard .mid file.
Is the audio to MIDI converter free?
Yes, completely free with no signup and no watermark. The converted MIDI downloads directly to your device.
What can I do with the MIDI file?
Open it in any DAW (Ableton, FL Studio, Logic, GarageBand, etc.) to change the instrument, fix notes, harmonize, or build a full arrangement around your melody. You can also use it as a starting point and then turn the finished song into a music video with Solmi.
