Detailed Description

Virtual analog stereo oscillator with band-limited waveforms.

StereoOscillator generates classic analog waveforms (saw, square, triangle, etc.) using band-limited lookup tables to avoid aliasing. It includes post-processing effects like wavefolding and asymmetry for additional timbral variation.

Key Features:

• Band-limited waveforms (no aliasing)
• Multiple classic waveforms (saw, square, triangle, sine, etc.)
• Pulse width modulation for square/pulse waves
• Wavefolding for harmonic distortion
• Asymmetry/waveshaping for timbral variation
• Independent left/right gain control

Parameters (via Params struct):

• wave: Waveform type (saw, square, triangle, etc.)
• leftGain/rightGain: Independent stereo output gains
• pw: Pulse width (0.0 to 1.0) for square/pulse waves
• fold: Wavefolding amount (0.0 to 1.0)
• asym: Asymmetry/waveshaping amount (0.0 to 1.0)

Usage:

BandLimitedLookupTables bllt;
StereoOscillator osc(bllt);
osc.setSampleRate(44100.0);
osc.noteOn(); // Initialize phase
 
StereoOscillator::Params params;
params.wave = Wave::sawUp;
params.pw = 0.5f;
params.fold = 0.3f;
 
osc.process(60.0f, params, audioBuffer); // MIDI note 60 (C4)
