initialize()

void initialize ( SpeakerArrangement busses )

overridevirtual

Mandatory method to setup parameters and I/O busses. See add_param(), add_input_bus() / add_output_bus(). This method will be called once per instance after construction.

Implements AudioProcessor.

reset()

void reset ( uint64 target_stamp )

overridevirtual

Reset all state variables.

Implements AudioProcessor.

render()

void render ( uint n_frames )

overridevirtual

Method called for every audio buffer to be processed. Each connected output bus needs to be filled with `n_frames`, i.e. `n_frames` many floating point samples per channel. Using the AudioSignal::OBusId (see add_output_bus()), the floating point sample buffers can be addressed via the BusConfig structure as: `bus[obusid].channel[nth].buffer`, see FloatBuffer for further details. The AudioSignal::IBusId (see add_input_bus()) can be used correspondingly to retrieve input channel values.

Implements AudioProcessor.
