* Attempt to use BS2B when using headphones without HRTFChris Robinson2014-11-221-20/+23
|
* Rework HRTF decision logicChris Robinson2014-11-221-36/+53
| | | | | | This way takes into account a new stereo-mode config option, which when set to "headphones" will default to using HRTF. Eventually the device will also be able to specify if headphones are being used.
* Move a warning check earlierChris Robinson2014-11-221-8/+8

* Use a different method for HRTF mixingChris Robinson2014-11-221-3/+11
| | | | | | | | | | | | | | | | | | | | | | | This new method mixes sources normally into a 14-channel buffer with the channels placed all around the listener. HRTF is then applied to the channels given their positions and written to a 2-channel buffer, which gets written out to the device. This method has the benefit that HRTF processing becomes more scalable. The costly HRTF filters are applied to the 14-channel buffer after the mix is done, turning it into a post-process with a fixed overhead. Mixing sources is done with normal non-HRTF methods, so increasing the number of playing sources only incurs normal mixing costs. Another benefit is that it improves B-Format playback since the soundfield gets mixed into speakers covering all three dimensions, which then get filtered based on their locations. The main downside to this is that the spatial resolution of the HRTF dataset does not play a big role anymore. However, the hope is that with ambisonics- based panning, the perceptual position of panned sounds will still be good. It is also an option to increase the number of virtual channels for systems that can handle it, or maybe even decrease it for weaker systems.

|
* Fix 5.1 surround soundChris Robinson2014-11-071-60/+69
| | | | | | | | | | | | | Apparently, 5.1 surround sound is supposed to use the "side" channels, not the back channels, and we've been wrong this whole time. That means the "5.1 Side" is actually the correct 5.1 setup, and using the back channels is anomalous. Additionally, this means the 5.1 buffer format should also use the the side channels instead of the back channels. A final note: the 5.1 mixing coefficients are changed so both use the original 5.1 surround sound set (with the surround channels at +/-110 degrees). So the only difference now between 5.1 "side" and 5.1 "back" is the channel labels.
* Support AL_EXT_MULAW_BFORMATChris Robinson2014-10-311-1/+3

* Add preliminary AL_EXT_BFORMAT supportChris Robinson2014-10-311-7/+13
| | | | | Currently missing the AL_ORIENTATION source property. Gain stepping also does not work.
* Make alcSuspendContext and alcProcessContext batch updatesChris Robinson2014-10-121-4/+135
| | | | | | | | | | This behavior better matches Creative's hardware drivers and Rapture3D's OpenAL driver. A compatibility environment variable is provided to restore the old no-op behavior for any app that behaves badly from this change (set __ALSOFT_SUSPEND_CONTEXT to "ignore"). If too many apps have a problem with this, the default behavior may need to be changed to ignore, with the env var providing an option to defer/batch instead.

* Disable the autowah effectChris Robinson2014-08-061-0/+4
| | | | | | | | There's apparently some issues with it causing noise or killing the output. It might be due to the per-sample changes being too harsh for the filter to keep up with, but it's not something I can take care of in time for release. This commit should be reverted after release when work on fixing it can resume.
