* Use 2-channel UHJ for stereo outputChris Robinson2016-02-261-6/+6

* Remove a dead assignmentChris Robinson2016-02-161-1/+0
|
* Add special HRTF handling for reverbChris Robinson2016-02-061-1/+77
| | | | | | | This is pretty hacky. Since HRTF normally renders to B-Format with two "extra" channels for the real stereo output, the panning interpolates between a panned reverb channel on B-Format, and two non-panned reverb channels on stereo output, given the panning vector length.
* Only apply the +3dB reverb gain boost to the ambient response.Chris Robinson2016-02-061-2/+1

* Avoid an extra sample of delay in the reverb modulatorChris Robinson2016-02-051-4/+6
|
* Remove an unnecessary variable and move duplicate code to a common spotChris Robinson2016-02-051-37/+23
|
* Don't explicitly check for LFEChris Robinson2016-02-051-16/+0
| | | | It's going to be set to 0 gain anyway
* Boost the direct-pan reverb to better match the expected volumeChris Robinson2016-02-051-0/+2
| | | | | Hopefully. Would be nice to have a reference implementation for this style of reverb to compare with.
* Update a couple outdated commentsChris Robinson2016-02-051-3/+1

* Apply the early and late reverb gains with the panning gainsChris Robinson2016-02-051-26/+28

* Better organize the reverb code into separate labeled sectionsChris Robinson2016-02-051-425/+442

* Separate early and late reverb output for standard reverb tooChris Robinson2016-02-051-33/+27
|
* Modify how the four output reverb points are calculatedChris Robinson2016-02-051-40/+62
| | | | | For HRTF and B-Format output, the points no longer move but instead scale based on the desired panning direction.
* Try to map reverb outputs directly to output channelsChris Robinson2016-02-011-2/+77
| | | | | | | | | HRTF and B-Format output still need to use virtual panning directions, but the reverb works better when it outputs directly to an output channel. Ambient and directional panning is used to properly mask and attenuate each output channel. Note that currently the "direct panning" output is quieter than it should be. Work is underway to attenuate the early reflections and late reverb better.

|
* Pass in the Q parameter for setting the filter parametersChris Robinson2015-11-014-21/+36
| | | | Also better handle the peaking filter gain.
* Use modff to split the modulation delay componentsChris Robinson2015-10-311-4/+3
|
* Mix reverb to output in the inner loopChris Robinson2015-10-291-41/+39

* Do up to 256 samples per reverb inner loop iterationChris Robinson2015-10-291-2/+3
|
* Always update all reverb propertiesChris Robinson2015-10-281-68/+44
| | | | | | The EAX-only effect properties will be set to compatible defaults when standard reverb is set, and the EAX-only effects will be skipped during sample processing.
* Do multiple samples at once in each reverb componentChris Robinson2015-10-281-245/+267

|
* Avoid taking the square-root of the ambient gainChris Robinson2014-10-116-40/+20
| | | | | | Although it is more correct for preserving the apparent volume, the ambisonics- based panning does not work on the same power scale, making it louder by comparison.
