Detailed Description

Sine-based waveshaping distortion effect based on AirWindows plugins.

AirWindowsDistortion provides musical distortion using sine waveshaping with density control that can produce both soft saturation and aggressive clipping. Based on Chris Johnson's AirWindows plugins, it features integrated highpass filtering, automatic denormalization prevention, and 32-bit dithering.

Key Features:

Sine-based waveshaping for musical harmonics
Density control from subtle to extreme (-1 to 4)
Integrated highpass filter
Denormalization prevention for CPU efficiency
32-bit dithering for low-level detail
Dry/wet mix control
Output level scaling

Parameters:

density: Distortion amount (-1.0 to 4.0)
- Negative values: starved/compressed distortion
- Positive values: boosted/saturated distortion
- Values > 1.0: multiple waveshaping passes
highpass: Highpass filter amount (0.0 to 1.0)
output: Output level scaling (0.0 to 1.0+)
mix: Dry/wet blend (0.0 = dry, 1.0 = wet)

The density parameter uses sine waveshaping which produces odd harmonics, creating a warm, musical distortion character. Values above 1.0 apply multiple passes of waveshaping for increasingly aggressive distortion.

Usage:

AirWindowsDistortion distortion;
distortion.setSampleRate(44100.0);
 
// Subtle saturation
distortion.setParams(0.5f,  // moderate density
                    0.1f,  // slight highpass
                    0.8f,  // reduce output
                    0.7f); // 70% wet
 
distortion.process(audioBuffer);
 
// Aggressive clipping
distortion.setParams(2.0f,  // high density
                    0.3f,  // more highpass
                    0.6f,  // compensate output
                    1.0f); // fully wet
