* Add an option to reverse Z panning of mono sourcesChris Robinson2011-05-073-3/+11
| | | | | | | | | | | Applications that are not built around OpenAL's orientation system need to convert their given vectors to it. Depending on how this is done, it can lead to proper stereo (left-right) panning with improper surround sound (front-back) panning, which thusly sounds correct with stereo output and incorrect with 4+ channel output. This option is intended to help fix playback of such applications on surround sound systems, without having to resort to forcing stereo output.
* Combine duplicate arraysChris Robinson2011-05-061-64/+31

* Skip LFE with HRTF outputChris Robinson2011-05-061-0/+9

* Remove the device channel matrixChris Robinson2011-05-062-73/+1
|
* Use the panning algorithms to build the multi-channel source matrixChris Robinson2011-05-061-92/+132
| | | | | This prevents the stereo-duplication option from working. It should hopefully be restored soon.

* Check for the C99 restrict keywordChris Robinson2011-05-023-0/+20
| | | | | GCC does not default to C99 mode yet, so does not know restrict, however it still allows using __restrict in its place

* Document the hrtf config optionChris Robinson2011-05-011-0/+7
|
* Add an HRTF filter for mono sourcesChris Robinson2011-05-017-17/+2203
| | | | | | | | | | The data is based on the KEMAR HRTF data provided by MIT, which can be found at <http://sound.media.mit.edu/resources/KEMAR.html>. The compact measurements were used. See hrtf_tables.inc for more information. The filter is only available for stereo output, using a 44100hz playback rate. Note also that it currently only applies to mono sounds, and the cf_level and head_dampen config options are ignored while it is active.

* Add support for packed 24-bit samplesChris Robinson2011-04-265-1/+170
|
* Add a compatibility option to treat cone angles as half anglesChris Robinson2011-04-223-2/+11
| | | | | | | | | | All previous versions of the library treated the source cone angles as half angles, which is contrary to the spec. Setting the __ALSOFT_HALF_ANGLE_CONES environment variable to "true" or "1" restores the buggy behavior for compatibility with applications that expect it. This is not a config file option because new apps should not be made to depend on the old behavior.
* Convert full-width cone angle source properties to half-widthChris Robinson2011-04-221-3/+3
| | | | | | The spec intends the property values to be the full angle encompassed by the cones, but the calculation interprets them as the angle from the center point.
* Apply the device matrix to the multi-channel source matrixChris Robinson2011-04-141-72/+74
| | | | | | | Mono sources and effects already output according to the available output device channels. Multiplying the device matrix with the source matrix results in a matrix that has the same effect as applying the source matrix followed by the device matrix, so all the channel remixing can be done in one place.

* Only set relevant device matrix entriesChris Robinson2011-04-121-30/+35
