* Avoid holding HRTF accumulation samples per-sourceChris Robinson2019-11-035-55/+27
| | | | | | It notably simplifies things to mix HRTF sources into an accumulation buffer together, which the Dry buffer's Ambisonic-to-HRTF decode is then added to, before being mixed to the Real output.
* Avoid direct function template and alias typesChris Robinson2019-10-031-2/+2
| | | | | | | It's somewhat ambiguous what they mean. Sometimes acting as a pointer, other times having weird behavior. Pointer-to-function types are explicitly defined as such, whereas uses of these tend to be as references (never null and not changeable).

* Clean up some ALfloat -> floatChris Robinson2019-10-025-68/+62

* Move ALvoice from alu.h to a separate headerChris Robinson2019-10-022-4/+13

* Repack the bsinc resamplers coefficientsChris Robinson2019-09-293-12/+12
| | | | | | This puts the base coefficients and the phase deltas next to each other. This improves caching, as the base and phase deltas are always used together while the scales are only used for the non-fast versions.
* Implement a "fast" bsinc pathChris Robinson2019-09-264-1/+118
| | | | | | | | | | This takes advantage of the fact than when increment <= 1 (when not down- sampling), the scale factor is always 0. As a result, the scale and scale-phase deltas never contribute to the filtered output. Removing those multiply+add operations cuts half of the work done by the inner loop. Sounds that do need to down-sample (when played with a high pitch, or is 48khz on 44.1khz output, for example), still go through the normal bsinc process.

* Only use one accumulation buffer for B-Format HRTF mixingChris Robinson2019-09-031-15/+11
| | | | | It's all getting added together anyway and all channels are continuous inputs, so this is fewer passes over various buffers.
