* Clean up some math stuffChris Robinson2018-12-226-38/+47
|
* 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

* 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.

* Use the AmbiUpsampler with higher order basic and custom panningChris Robinson2018-12-172-96/+47
| | | | Also allocate the BFormatDec and AmbiUpsampler where they're (re)set.
* Avoid hard-coded scale factors in BFormatDec's upsamplerChris Robinson2018-12-171-23/+36

|
* 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.
