clone_audio_buffer_for_channels()

std::vector< std::shared_ptr< AudioBuffer > > MayaFlux::Buffers::BufferSupplyMixing::clone_audio_buffer_for_channels	(	const std::shared_ptr< AudioBuffer > &	buffer,
		const std::vector< uint32_t > &	channels,
		ProcessingToken	token
	)

Clones an audio buffer for each channel in the specified list.

Parameters

buffer	Buffer to clone
channels	Vector of channel indices to clone for
token	Processing domain

Creates a new buffer for each specified channel, copying the structure but maintaining independent data. Useful for multi-channel processing where each channel needs its own processing chain.
