root_audio_buffer() [2/2]

InspectResult MayaFlux::Portal::Forma::Inspector::root_audio_buffer	(	Buffers::ProcessingToken	token,
		uint32_t	channel,
		Surface &	surface,
		LayoutCursor &	cursor,
		float	x_min = -0.95F,

	)

Inspect the root audio buffer for a specific token and channel.

Header shows channel index and token. Rows show sample count and child count. The root buffer itself is expanded via buffer(), then each child buffer is expanded via buffer() in order.
