*	Clarify some macro names using ambisonic mixed-mode notation	Chris Robinson	2018-02-09	1	-8/+8
\|
*	Replace some freq_mult variable names with f0norm	Chris Robinson	2018-01-13	1	-2/+2
\| \| \| \| \| \|	The latter is a bit more descriptive as f0 is often used to denote the reference frequency of a filter, so f0norm indicates the normalized reference frequency (ref_freq / sample_rate).
*	Add a front-stablizer config option for surround sound modes	Chris Robinson	2017-07-31	1	-0/+8
\| \| \| \| \| \| \| \| \| \| \| \|	This improves a stereo (front-left + front-right) sound "image" by generating a front-center channel signal. Done correctly, it helps reduce the comb effects and phase errors associated with using only two speakers to simulate center sounds. Note that it shouldn't be used if the front-center channel is already included in the positional audio mix (the dialog effect is okay). In general, it may actually be better to exclude the front-center channel from the positional audio mix and use this to generate front-center output.
*	Add an all-pass filter that replicates the band splitter's phase shift	Chris Robinson	2017-07-19	1	-0/+12

*	Don't use periphonic FOA when the HOA decoder is not periphonic	Chris Robinson	2017-02-19	1	-0/+1

*	Replace more ALuint with ALsizei	Chris Robinson	2017-01-29	1	-1/+1
\|
*	Improve the ambisonic upscaling methods	Chris Robinson	2017-01-24	1	-0/+18
\| \| \| \| \| \| \| \|	This now takes advantage of the differences seen in generated decoder matrices for first-order compared to second- and third-order, such that with the appropriate frequency-dependent scaling applied to first-order content, the result is identical with a higher-order decoder matrix compared to a first- order matrix for the same layout.
*	More ALsizei, with the B-Format decoder	Chris Robinson	2017-01-16	1	-4/+4
\|
*	Use ALsizei in a few more places	Chris Robinson	2017-01-16	1	-1/+1
\|
*	Make some pointer-to-array parameters const	Chris Robinson	2016-10-04	1	-3/+3
\|
*	Band-split the HRIRs when building the ambisonic decoder filters	Chris Robinson	2016-08-21	1	-0/+15
\| \| \| \| \|	This allows each HRIR to contribute a frequency-dependent response, essentially acting like a dual-band decoder playing over the cube speaker array.
*	Add a stand-alone upsampler for higher-order ambisonic oputput	Chris Robinson	2016-07-30	1	-0/+10
\|
*	Add a config option for distance compensation	Chris Robinson	2016-03-26	1	-1/+5

*	Up-sample first-order content when using a higher order HQ decoder	Chris Robinson	2016-03-23	1	-0/+5
\|
*	Add a specific output for first-order sources	Chris Robinson	2016-03-22	1	-0/+1
\|
*	Add a dual-band ambisonic decoder	Chris Robinson	2016-03-15	1	-0/+14
	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.
