Detailed Description

template<FloatType T>
struct dspark::AlgorithmicReverb< T >::SmoothRandomLFO

Hermite-interpolated random noise generator for organic modulation.

Generates band-limited random values via cubic Hermite (Catmull-Rom) interpolation between xorshift32 random targets. Produces smooth, non-periodic modulation - the key to Lexicon-quality reverb character.

◆ next()

template<FloatType T>

◆ nextStride()

template<FloatType T>
T dspark::AlgorithmicReverb< T >::SmoothRandomLFO::nextStride ( int  stride)
inlinenoexcept

Advances the LFO by stride samples in one call.

Used by Eco quality to run modulation at control rate: the phase advances by stride * phaseInc_ so the effective LFO frequency is unchanged. Rates are clamped well below 1/stride of the sample rate, so at most one Hermite target is consumed per call.
