* Update COPYING to the latest ↵François Cami2014-08-181-2/+2
| | | | https://www.gnu.org/licenses/old-licenses/lgpl-2.0.txt to fix the FSF' address Fix the FSF' address in the source
* Properly scale the first HRTF pass-through coefficientChris Robinson2014-07-171-4/+8
| | | | | Coefficients are scaled by 32767. For pass-through, this is attenuated by sqrt(0.5) to maintain a consistent perceived volume.
* Cleanup some HRTF codeChris Robinson2014-07-161-68/+53
| | | | Use loops instead of duplicating code, rewrite some lines to be clearer.
* Fix omni-directional moving HRTF coeffsChris Robinson2014-07-141-4/+4

* Add a source radius property that determines the directionality of a soundChris Robinson2014-07-111-32/+56
| | | | | | | | | At 0 distance from the listener, the sound is omni-directional. As the source and listener become 'radius' units apart, the sound becomes more directional. With HRTF, an omni-directional sound is handled using 0-delay, pass-through filter coefficients, which is blended with the real delay and coefficients as needed to become more directional.
* Only set the needed HRTF coefficientsChris Robinson2014-06-211-2/+2

|
* Update HRTF codeChris Robinson2012-09-111-197/+330
| | | | | | | | | | | 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.
