* Handle padding between device sample framesChris Robinson2019-12-211-17/+17
| | | | | | | | The padding must be constant and sample type aligned (e.g. some fixed multiple of two bytes between the start of two consecutive frames for 16-bit output). The intent is to always have the ability for stereo output with WASAPI even if the device has some other unsupported configuration, as long as front-left and front-right exist.
* Use unique setters for biquad filter parametersChris Robinson2019-12-211-20/+13
| | | | One for whether a slope parameter is used, and one for bandwidth.
* Improve gain/hf/lf packing when processing voice updatesChris Robinson2019-12-211-96/+84
|
* Remix missing channels with direct channels enabledChris Robinson2019-12-191-1/+15
| | | | Instead of dropping them.
* Don't apply direct channels with mono outputChris Robinson2019-12-181-1/+1
|
* Don't process direct channel sources with attenuationChris Robinson2019-12-171-4/+4
|
* Update a comment since B-Format input isn't always FuMaChris Robinson2019-12-171-2/+2
|
* Correctly scale spatialized B-Format sourcesChris Robinson2019-12-171-2/+2
|
* Use normal panning for B-Format outputChris Robinson2019-12-171-1/+1
| | | | It can never work since it only uses auxiliary channel labels.
* Don't apply stereo panning with direct channels enabledChris Robinson2019-12-171-3/+6
|
* Handle the buffer's ambisonic propertiesChris Robinson2019-12-021-12/+24
|
* Make B-Format rotation more robustChris Robinson2019-12-011-34/+203
| | | | | This should now handle higher orders, and can be easily extended to non-FuMa layouts and scalings.
* Avoid static constexpr for arrays iterated over at run-timeChris Robinson2019-10-251-1/+1
|
* Use better types for some specific sizesChris Robinson2019-10-131-15/+15
|
* Use std::array instead of plain arrays in a couple placesChris Robinson2019-10-051-7/+2
|
* Move ALvoice from alu.h to a separate headerChris Robinson2019-10-021-7/+37
|
* Check MAX_RESAMPLER_PADDING properly to ensure it's large enoughChris Robinson2019-09-281-0/+4
|
* Combine two function calls into oneChris Robinson2019-09-281-42/+102
|
* Add "fast" variants for the bsinc resamplersChris Robinson2019-09-281-4/+4
| | | | | | 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 Robinson2019-09-261-2/+2
| | | | | | | | | | 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.

* Use a normal vector for the voices arrayChris Robinson2019-09-041-5/+2
|
* Increment the mix count during disconnectChris Robinson2019-09-041-1/+3
| | | | | So attempts to get the current playback offset behave correctly while disconnecting.

* Update some includesChris Robinson2019-08-051-1/+1
|
* Move the meters per unit property to the listenerChris Robinson2019-08-051-2/+1
|
* Remove the ReverbSpeedOfSound hackChris Robinson2019-08-051-79/+55
| | | | | | | No other effect depends on context or listener properties, so reverb being the only exception for speed of sound and meters per unit was putting extra work on the effect engine for no real reason. Especially since the reverb decay time should be the time actual time to decay irrespective of other settings.
