Detailed Description

template<typename SampleType = float>
class pulp::signal::DitherQuantizerT< SampleType >

Stateful deterministic wrapper for per-sample and block processing.

RT contract: all state is fixed-size scalar storage. process, reset, and every setter allocate nothing, take no locks, and do not throw. The random stream advances only when TPDF is enabled and the quantizer is active.
