Load a pluck, bass, bell or key hit. The tool searches a built-in 4-operator FM synth for the closest patch, scores the match honestly, and shows where on the keyboard the sound holds up. All in your browser, nothing uploaded.

It compares spectrograms and loudness shape, tries six voice types, then refines the best ones.
A match percentage tells you if it is close, rough, or if the search came up empty.
Operator ratios, levels and envelopes in plain numbers, to rebuild in Sytrus or any FM synth. Download the WAV or preset too.
Your files never leave your device. This is our own FM engine, not Sytrus itself, so treat the result as a very good starting patch. One clean note works best.
