ACADEMIC & ALGORITHMIC REFERENCERESEARCH & LEARNING VAULT // Optical Delay Theremin & Microtonal Synthesis
Continuous pitch heterodyning, low-pass filter resonance, and velocity tape delay.
// HISTORICAL ORIGINS
Leon Theremin invented the electronic theremin in 1920 as the world's first gestural electronic instrument played without physical contact.
// GOVERNING EQUATIONS
f(x) = f_{min} \cdot \left(\frac{f_{max}}{f_{min}}\right)^x, \quad y(t) = x(t) + g \cdot y(t - \tau)// BROWSER IMPLEMENTATION
Maps 2D pointer coordinates exponentially to oscillator frequencies and biquad filter cutoffs with WebAudio feedback delay lines.
