void ARDOUR::VBAPanner::distribute	(	BufferSet &	ibufs,
		BufferSet &	obufs,

	)

virtual

Pan some input buffers to a number of output buffers.

Parameters

ibufs	Input buffers (one per panner input)
obufs	Output buffers (one per panner output).
gain_coeff	fixed, additional gain coefficient to apply to output samples.
nframes	Number of samples in the input.

Derived panners can choose to implement these if they need to gain more control over the panning algorithm. The default is to call distribute_one() or distribute_one_automated() on each input buffer to deliver it to each output buffer.

If a panner does not need to override this default behaviour, it can just implement distribute_one() and distribute_one_automated() (below).

Reimplemented from ARDOUR::Panner.
