* Repack some AmbiUpsampler fields for better access patternsChris Robinson2018-12-232-16/+18

* Properly rebalance the HF scale with ambisonic upsamplingChris Robinson2018-12-231-5/+32
|
* Mix effect slot output to the effect target if it's setChris Robinson2018-12-2312-61/+179
|
* Dynamically sort the effect slots when mixingChris Robinson2018-12-222-4/+45
| | | | | | | | | This is to be able to support effects that output to other effects. When an effect outputs to another effect, the former needs to process first, so the former mixes to the latter's buffer before the latter is processed. This sorting needs to happen in the mixer because the effect slot's "Target" property changes asynchronously.
* Cleanup definitions and declarations in reverb.cppChris Robinson2018-12-221-253/+221

* Fix for C++11 compatibilityChris Robinson2018-12-221-4/+4
| | | | std::array::operator[] isn't constexpr until C++14.
* Use a normal delete instead of ll_ringbuffer_freeChris Robinson2018-12-2212-169/+119
| | | | And use RingBufferPtr in more places
* A bit of cleanup for CalcPanningAndFiltersChris Robinson2018-12-221-24/+30

* Rename a couple HRTF structsChris Robinson2018-12-226-79/+78

* Don't convert the HRTF decoder virtual speaker positions to radiansChris Robinson2018-12-213-33/+32
|
* Use a dodecahedron for the ambisonic HRTF decodeChris Robinson2018-12-211-68/+51
| | | | | | | Also uses full second-order for "basic" HRTF rendering. Note that the supplied matrix is full third-order, but only the first- and second-order coefficients are used. The base matrices are the identical, only differing by the high- frequency scalars.

|
* Avoid extraneous alignment requirementsChris Robinson2018-12-161-2/+2
|
* Put the ACN index map in a headerChris Robinson2018-12-154-82/+88
| | | | Also put it and the Ambisonic scales in a more appropriate header.
* Reorder some math terms to help optimizationsChris Robinson2018-12-151-6/+6
| | | | | | | | | | | | | | | | | | | | | | | Because floating-point math is not associative ((a*b)*c does not necessarily give the same result as a*(b*c)), the ordering of terms can inhibit reuse of temporary values. For example, both coeffs[9] = 2.091650066f * y * (3.0f*x*x - y*y); and coeffs[15] = 2.091650066f * x * (x*x - 3.0f*y*y); contain x*x and y*y terms that could be calculated once, stored in temporary registers, and reused to multiply with 3. But since 3.0f*(x*x) would produce different results, the compiler is not allowed to make that optimization. If, however, the multiply with 3 is moved to the right side: coeffs[9] = 2.091650066f * y * (x*x*3.0f - y*y); and coeffs[15] = 2.091650066f * x * (x*x - y*y*3.0f); in both cases x*x and y*y are calculated first in their respective groups, guaranteeing the same results for both instances prior to the multiply with 3 and allowing the compiler to reuse those intermediate values.
