* Allow second-order HQ decodingChris Robinson2016-03-232-10/+27
| | | | | | | | Could really do with some optimizations to the mixing gain calculations. For ambisonic targets, the coefficients will only have 1 non-0 entry for each output, so the double loop in unnecessarily wasteful. Similarly, most uses won't need a full height encoding either, so a horizontal-only or mixed-order target could reduce the number of channels.
* Add a specific output for first-order sourcesChris Robinson2016-03-229-5/+62

* Simplify setting the matrix coeffsChris Robinson2016-03-221-42/+14
|
* Add a workaround for a buggy modffChris Robinson2016-03-181-0/+15

* Store the effect's output buffer in the effect stateChris Robinson2016-03-174-6/+16

* Make sure enough reverb panning gains are definedChris Robinson2016-03-161-4/+4

* Rename the BFormat channels to AuxChris Robinson2016-03-163-28/+28

* Add config options to enable the hq ambisonic decoderChris Robinson2016-03-163-39/+59

* Properly handle negative matrix values and fix decoder initializationChris Robinson2016-03-152-2/+2
|
* Replace the custom layout options with an ambdec loaderChris Robinson2016-03-151-129/+87
| | | | | The ambisonic layout options were never very good for clarity or flexibility. Hopefully using ambdec files will prove to be better.
* Rename a couple functions for more informative loggingChris Robinson2016-03-151-9/+10
|
* Add a dual-band ambisonic decoderChris Robinson2016-03-159-16/+467
| | | | | | | | | | 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.
* Downgrade some ERRs to WARNs or TRACEsChris Robinson2016-03-151-8/+9

* Use second-order coefficients for 5.1Chris Robinson2016-03-131-16/+16
| | | | | Since the panning only drives 5 speakers, it shouldn't use more than 5 ambisonic channels (9 total in second order, minus 4 for unused height).

* Remove the extra scaling on W for UHJ encodingChris Robinson2016-03-012-10/+28
| | | | | | There seems to be some inconsistent info about whether W should be scaled by sqrt(2) for encoding. Not applying the scaling results in a wider stereo image, which seems more appropriate.
