🎤 Music Singing: 2D Voice Source-Filter Cross-Section

Interactive 2D cross-section of the singing voice built on the source-filter model: vocal folds vibrating as a loaded string set the pitch, and a draggable tongue reshapes the vocal tract so its resonances (formants) pick out vowels from the harmonic spectrum, with live spectrum, note name, loudness and optional sound.

ControlsDrag the tongue marker to move between vowels; drag the gold larynx handle to change vocal fold tension and pitch; sliders for fold length, lung pressure, glottal open quotient, vocal tract length and slow-motion factor; toggles for vibrato, singer's formant and sound; presets for bass, tenor, alto and soprano voices.
