* Add "fast" variants for the bsinc resamplersChris Robinson2019-09-281-2/+2
| | | | | | This simply omits the scale factor from the filter, similar to how up-sampling does. The consequence of this is less smooth transitions when ramping the pitch while down-sampling, but otherwise behaves fine.
* Implement a "fast" bsinc pathChris Robinson2019-09-261-1/+1
| | | | | | | | | | 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.
