process_input()

int MayaFlux::Core::AudioSubsystem::process_input	(	double *	input_buffer,
		unsigned int	num_frames
	)

Processes input data from audio interface.

Parameters

input_buffer	Pointer to interleaved input data
num_frames	Number of frames to process

Returns

Status code (0 for success)

Handles incoming audio data from the audio interface, converting from interleaved format and routing to appropriate buffer channels for processing.
