Audio Processing Algorithms

Ring Modulation (Robot Voice)

const modulator = Math.sin(2 * Math.PI * 30 * i / sampleRate);
robotData[i] = crushed * (0.7 + 0.3 * modulator);

Time Stretching (Pitch Shifting)

High-quality resampling technology using linear interpolation.

Feedback Processing (Howling)

const feedback = audioData[i - delayTime] * 0.4;
const distorted = Math.tanh(originalSample + feedback);
