* Copy samples if needed in the 'copy' resamplerChris Robinson2014-05-211-9/+15
|
* Return a sample pointer from resamplersChris Robinson2014-05-191-8/+7
| | | | Both resampling and filtering now avoid copying samples when they no-op.
* 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
|
* Add a ALfilterState method to process multiple samples at onceChris Robinson2014-05-181-0/+8
|
* Always use the current gains when mixingChris Robinson2014-05-041-4/+6
| | | | | | 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.
* Remove the last bits of the predictive sample processingChris Robinson2014-03-231-2/+2
|
* Remove the click removal buffers for auxiliary effect slotsChris Robinson2014-03-231-1/+1
|
* Identity gain step is 1, not 0Chris Robinson2014-03-231-1/+1
|
* Add gain stepping to the send mixersChris Robinson2014-03-231-16/+24
|
* 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 Robinson2014-03-231-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | 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 Robinson2014-02-231-2/+7
| | | | | | | | | This reverts commit 25b9c3d0c15e959d544f5d0ac7ea507ea5f6d69f. Conflicts: Alc/mixer_neon.c Unfortunately this also undoes the Neon-enhanced ApplyCoeffsStep method.
* Apply HRTF coefficient stepping separatelyChris Robinson2013-11-101-7/+2
|
* Use an UNUSED macro instead of void-tagging unused parametersChris Robinson2013-10-071-4/+3
|
* Use a macro for the silence thresholdChris Robinson2013-10-061-2/+2
|
* Don't store the effect slot in SendParamsChris Robinson2013-10-061-10/+10
| | | | 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.
* Use C99's inline instead of __inlineChris Robinson2013-05-281-12/+12

|
* Update HRTF codeChris Robinson2012-09-111-2/+4
| | | | | | | | | | | 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.
