* 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.
* Don't feed the HRTF mix to the click removal and pending click buffersChris Robinson2014-03-231-40/+3
| | | | | The coefficients (which control the volume and panning) already use stepping to non-abruptly fade the mix.
* Step mixing gains per-sample for non-HRTF mixingChris Robinson2014-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Revert "Apply HRTF coefficient stepping separately"Chris Robinson2014-02-231-4/+5
| | | | | | | | | This reverts commit 25b9c3d0c15e959d544f5d0ac7ea507ea5f6d69f. Conflicts: Alc/mixer_neon.c Unfortunately this also undoes the Neon-enhanced ApplyCoeffsStep method.

* Update HRTF codeChris Robinson2012-09-111-7/+10
| | | | | | | | | | | 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.
