* Only apply ambient gain to available output channelsChris Robinson2010-04-271-10/+15
|
* Add an option to scale the output mixChris Robinson2010-04-231-14/+15
|
* Make stereo duplication a property of the deviceChris Robinson2010-04-201-2/+8
| | | | Further, don't use it with mono/stereo output
* Translate the source position separatelyChris Robinson2010-04-161-11/+7
| | | | | | | | | | | | | | This is to handle the case where an app specifies the same values for the source and listener, and expects centered panning. This fails due to floating- point errors in the matrix, causing the result to be ever-so-slightly off of 0. This error would normally be hidden by the position normalization, which will not lengthen a distance shorter than the reference distance so the panning would be nearly imperceptible. But that also fails if the reference distance is set to 0, causing the position to expand to a full unit. Keep the 4x4 matrix calculations, however. It will still be useful for the requested listener matrix extension.

|
* Store the panning LUT in the deviceChris Robinson2010-04-081-14/+109
|
* Use a single layout for the virtual speakersChris Robinson2010-04-081-1/+1
| | | | The downmix should probably be improved to take the angles into account

|
* Always mix internally at 8.1Chris Robinson2010-04-081-196/+149
| | | | | The channels are remixed when writing to the output buffer. Stereo duplication is currently broken, but this can be restored later
