* Avoid sampling beyond the end of the loopChris Robinson2010-09-241-6/+6
|
* Localize some variables to the mixer macrosChris Robinson2010-09-241-51/+84
| | | | | | The hope here is to help break the mixer loops into separate functions, so the macro expansion doesn't cause the MixSource function to explode in size and kill compilation speed.
* Use separate mixing loops for the dry path and wet pathsChris Robinson2010-09-241-92/+234
| | | | | | | | | | | | This will increase CPU use a bit for sources that use auxiliary sends (particularly with the cosine resampler), but it makes it more scalable when adding more sends per source. Additionally, it will improve performance of sources that don't use auxiliary sends. The cosine resampler can probably be improved by using a lookup table instead of calling cos() as there are 14 bits of fractional precision, so a 16384- element float array would cover it all. This can also be reduced to a half or quarter size if the precision loss is found to be acceptable.

* Duplicate stereo sources by defaultChris Robinson2010-09-223-6/+10
| | | | | The mixer is smart enough now to handle proper volume adjustments depending on the number of output speakers

* Implement AL_SOFT_buffer_sub_data using the current AL_EXT_buffer_sub_data specChris Robinson2010-09-215-9/+28
| | | | | | This extension can be useful for some applications, but a full EXT version may not be ready for some time. Using the SOFT moniker will help differentiate it in case changes need to be done for the EXT version.
