* Check the absolute gain value for silenceChris Robinson2014-10-311-1/+1
| | | | | Future B-Format support will be using negative gains, which still need to be applied.
* Combine the direct and send mixersChris Robinson2014-06-131-85/+26
|
* Combine some dry and wet path typesChris Robinson2014-06-131-9/+9
|
* The lower value of the gain vector contains the closest target valueChris Robinson2014-05-211-2/+2
|
* Don't pass the SendParams to the wet-path mixerChris Robinson2014-05-181-8/+6
|
* Don't pass the DirectParams to the dry-path mixerChris Robinson2014-05-181-7/+6
|
* Pass some DirectParams as function parametersChris Robinson2014-05-181-4/+3
|
* Use _mm_setr_ps instead of _mm_set_psChris Robinson2014-05-181-4/+4
| | | | | Apparently _mm_set_ps loads in reverse order compared to _mm_load_ps, so _mm_setr_ps should give what we really want.
* Remove unnecessary ifdefsChris Robinson2014-05-041-2/+0
| | | | | mixer_sse.c and mixer_neon.c are only compiled when the relavent headers are found anyway.
* Always use the current gains when mixingChris Robinson2014-05-041-7/+8
| | | | | | The current gain gets explicitly set to the target when the stepping is finished to ensure the target is still used. This way, however, will allow for asynchronously 'canceling' a fade by setting the counter to 0.
* Make sure all gain steps are applied with the SSE and Neon mixersChris Robinson2014-05-031-12/+13
|
* Use _mm_set_ps() to set an __m128 instead of {}Chris Robinson2014-04-261-2/+2
|
* Remove the click removal buffers for auxiliary effect slotsChris Robinson2014-03-231-1/+1
|
* Add gain stepping to the send mixersChris Robinson2014-03-231-23/+52
|
* Remove the now-unneeded click removal buffers for the deviceChris Robinson2014-03-231-1/+1
| | | | | | They are still there for auxiliary sends. However, they should go away soon enough too, and then we won't have to mess around with calculating extra "predictive" samples in the mixer.
* Step mixing gains per-sample for non-HRTF mixingChris Robinson2014-03-231-15/+41
| | | | | | | | | | | | | | | | | | | | | | | | This fades the dry mixing gains using a logarithmic curve, which should produce a smoother transition than a linear one. It functions similarly to a linear fade except that step = (target - current) / numsteps; ... gain += step; becomes step = powf(target / current, 1.0f / numsteps); ... gain *= step; where 'target' and 'current' are clamped to a lower bound that is greater than 0 (which makes no sense on a logarithmic scale). Consequently, the non-HRTF direct mixers do not do not feed into the click removal and pending click buffers, as this per-sample fading would do an adequate job of stopping clicks and pops caused by extreme gain changes. These buffers should be removed shortly.
* Store the HrtfState directly in the DirectParamsChris Robinson2014-03-231-2/+2
|
* Use a union to combine HRTF and non-HRTF mixer paramsChris Robinson2014-03-191-1/+1
|
* Revert "Apply HRTF coefficient stepping separately"Chris Robinson2014-02-231-7/+53
| | | | | | | | | This reverts commit 25b9c3d0c15e959d544f5d0ac7ea507ea5f6d69f. Conflicts: Alc/mixer_neon.c Unfortunately this also undoes the Neon-enhanced ApplyCoeffsStep method.
* Apply HRTF coefficient stepping separatelyChris Robinson2013-11-101-53/+7

* Use a macro for the silence thresholdChris Robinson2013-10-061-2/+2
|
* Don't store the effect slot in SendParamsChris Robinson2013-10-061-16/+15
| | | | This makes it much more like DirectParams.
* Use a separate value for the maximum buffer channelsChris Robinson2013-07-231-2/+2
| | | | | | | Unlike the device, input buffers are accessed based on channel numbers instead of enums. This means the maximum number of channels they hold depends on the number of channels any one format can have, rather than the total number of recognized channels. Currently, this is 8 for 7.1.
* Work around some problems with KDevelop's parserChris Robinson2013-06-181-0/+7

|
* Update HRTF codeChris Robinson2012-09-111-23/+86
| | | | | | | | | | | This update allows for much more flexibility in the HRTF data. It also allows for HRTF table file names to include "%r" to represent the device's playback rate (e.g. if you set hrtf-%r.mhr, then it will try to use hrtf-44100.mhr or hrtf-48000.mhr depending if the device's output rate is 44100 or 48000, respectively). The makehrtf utility has also been updated to support more options and input file formats, as well as the new mhr format.
* Use the right method to clear a __m128 to 0Chris Robinson2012-09-091-2/+2

* Use SSE to do 4 samples at once (non-HRTF direct mix), instead of to apply a ↵Chris Robinson2012-09-091-22/+43
