A channel vocoder splits both your voice and the piano into 16 frequency bands. Your voice's energy in each band controls how much of the corresponding piano band comes through — so the piano speaks in your formants.
Classic sibilance fix: broadband noise mixes into the carrier so “s” and “sh” sounds pass clearly. Tap the visualization bars = the live filterbank.
