* 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 the correct flag in the dsound backendChris Robinson2011-05-061-1/+1
|

|
* Update sources automatically when device parameters changeChris Robinson2011-05-061-24/+25
|

* Implement HRTF mixers for multi-channel sourcesChris Robinson2011-05-022-55/+447
|
* Use flags instead of separate boolsChris Robinson2011-05-013-13/+15
|
* Add an HRTF filter for mono sourcesChris Robinson2011-05-014-17/+2197
| | | | | | | | | | 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 a device flag for enabling HRTFChris Robinson2011-05-011-4/+8
|
* Be silent if the PulseAudio context fails to connect while probingChris Robinson2011-04-301-5/+6
|
* Add the SOFT moniker for the loopback extension functions and enumsChris Robinson2011-04-281-14/+14
|
* Allow MSVC to build a static libChris Robinson2011-04-271-0/+18
| | | | Based on a patch by Michał Cichoń <[email protected]>
* Add loopback device properties to the ALCenum listChris Robinson2011-04-271-0/+5
|
* Add a couple in-progress extensions to the extension listsChris Robinson2011-04-271-3/+4
|
* Add support for packed 24-bit samplesChris Robinson2011-04-261-0/+2
|
* Add a compatibility option to treat cone angles as half anglesChris Robinson2011-04-222-2/+9
| | | | | | | | | | 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.
* Fix LFE channel outputChris Robinson2011-04-141-0/+3
|
* Only set relevant device matrix entriesChris Robinson2011-04-121-30/+35
|
* Allow the buffer_samples API to be retrievedChris Robinson2011-04-101-0/+6

* Invert the device matrix row/columnChris Robinson2011-03-132-41/+41

* Add support for ALC_EXT_DEDICATEDChris Robinson2011-03-122-1/+134

* Better protect the device for multi-threading accessChris Robinson2011-03-121-35/+33
|
* Implement a basic non-real-time loopback deviceChris Robinson2011-03-112-11/+313
| | | | | | | | | | Currently it behaves just like a normal device except contexts are only processed during calls to alcRenderSamples. Additionally, the ALC_SYNC and ALC_REFRESH context attributes are not valid for these devices, and there are two new context attributes to specify the rendering format: ALC_FORMAT_TYPE and ALC_FORMAT_CHANNELS. These each take one of the type and channel enums added. This stuff is subject to change.
* Finalize the loop points extension as AL_SOFT_loop_pointsChris Robinson2011-02-091-2/+2

* Use the correct winmm device ID typeChris Robinson2011-02-081-2/+2
