Detailed Description

Modulated delay effect for chorus, flanger, and phaser effects.

Modulation uses an LFO to modulate a delay line, creating time-varying delay effects. By adjusting delay time, modulation rate, depth, and stereo width, you can create chorus, flanger, and phaser-like effects.

Key Features:

Sinusoidal LFO modulation
Stereo width control (independent L/R modulation)
Configurable delay time, rate, and depth
Wet/dry mix control
High-quality Lagrange interpolation

Parameters:

delay: Base delay time in seconds (typically 10-30ms)
rate: LFO frequency in Hz (typically 0.1-5 Hz)
depth: Modulation depth in seconds (how much delay varies)
width: Stereo width (0.0 = mono, 1.0 = full stereo L/R phase offset)
mix: Wet/dry mix (0.0 = dry, 1.0 = wet)

Effect Types:

Chorus: delay ~20ms, rate ~0.5Hz, depth ~10ms, mix ~0.5
Flanger: delay ~3ms, rate ~0.2Hz, depth ~5ms, mix ~0.5
Vibrato: delay ~5ms, rate ~5Hz, depth ~2ms, mix ~1.0

Usage:

Modulation chorus(0.03f); // 30ms max delay
chorus.setSampleRate(44100.0);
 
// Create a chorus effect
chorus.setParams(
    0.020f,  // 20ms base delay
    0.5f,    // 0.5 Hz modulation
    0.010f,  // 10ms depth
    0.5f,    // 50% stereo width
    0.5f     // 50% wet/dry mix
);
 
chorus.process(audioBuffer);
