Detailed Description

Bridges hardware audio input into the DSP graph as output ports.

Creates stereo and mono output ports for each hardware input channel pair. During processing, copies data from the hardware input provider into the appropriate output port buffers.

void zrythm::dsp::AudioInputProcessor::custom_process_block ( dsp::graph::ProcessBlockInfo time_nfo, const dsp::ITransport & transport, const dsp::TempoMap & tempo_map )

overridevirtualnoexcept

Custom processor logic after processing all owned parameters.

By default, this does passthrough to same-type ports.

Reimplemented from zrythm::dsp::ProcessorBase.
