process_audio_networks()

std::vector< std::vector< double > > MayaFlux::Nodes::NodeGraphManager::process_audio_networks	(	ProcessingToken	token,
		uint32_t	num_samples,
		uint32_t	channel = 0
	)

Process audio networks for a specific channel.

Parameters

token	Processing domain (should be AUDIO_RATE)
num_samples	Number of samples/frames to process
channel	Channel index within that domain

Returns

Vector of processed audio data from all networks for that channel

Processes all audio-sink networks registered to the specified channel and returns their combined output data.
