This only compensates for timing and gain differences caused by differences in
the physical speaker distances. It's not near-field compensation. This also
relies on having proper distance values defined in the ambdec definition file.
This uses a virtual B-Format buffer for mixing, and then uses a dual-band
decoder for improved positional quality. This currently only works with first-
order output since first-order input (from the AL_EXT_BFROMAT extension) would
not sound correct when fed through a second- or third-order decoder.
This also does not currently implement near-field compensation since near-field
rendering effects are not implemented.
