* Add distance compensation to the HQ decoderChris Robinson2016-03-261-4/+107
| | | | | | 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.

* Add a dual-band ambisonic decoderChris Robinson2016-03-151-0/+286
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.
