* Use SSE to do 4 samples at once (non-HRTF direct mix), instead of to apply a ↵Chris Robinson2012-09-091-22/+43

* Hold the device lock with PulseAudio between mixing and writingChris Robinson2012-08-181-0/+2
|
* Hold the device lock with ALSA between mixing and writingChris Robinson2012-08-181-0/+4
|
* Use non-blocking access for ALSA playbackChris Robinson2012-08-181-17/+37
|
* Move the device lock into the backend function tableChris Robinson2012-08-1816-11/+48
| | | | | For backend-specific implementations: this should hold the audio mixer loop for playback devices, and provide recursive mutex behavior.
* Keep the backend device open until the last reference is releasedChris Robinson2012-08-181-4/+5
| | | | | | This should generally happen with the next ALCdevice_DecRef call unless the device is in the middle of being used in another thread, in which case it's probably best to not remove the resources.
* Add the start of AL_SOFT_source_latencyChris Robinson2012-08-181-0/+3
| | | | | This extension will provide a way for apps to get accurate latency and playback position information
* Add a device method to retrieve the active latencyChris Robinson2012-08-1715-15/+155
| | | | | This is effectively the time until the next update will be heard by the user, or the closest approximation thereof, in nanoseconds.
* Place the alignment attribute before the variable declarationChris Robinson2012-08-161-1/+1
|
* Fix aligned allocator fallbackChris Robinson2012-08-161-3/+2
|
* Avoid dynamic handling of libsndioChris Robinson2012-08-161-81/+0
| | | | This makes it safer and easier to handle as OpenBSD updates it

* Don't bother handling MMX since we don't use itChris Robinson2012-08-151-8/+3
|
* Add cmake options to disable or require support for CPU extensionsChris Robinson2012-08-152-7/+13
|
* Move mixers into separate source filesChris Robinson2012-08-156-415/+590
|
* Add an SSE-enhanced HRTF mixer using intrinsicsChris Robinson2012-08-142-1/+51
| | | | Not as good as it could be, but it's something
* Add a config option to disable use of CPU extensionsChris Robinson2012-08-132-9/+42
|
* Allow building multiple types of mixers, selecting based on CPU capsChris Robinson2012-08-131-47/+64
|
* Check for some CPU extensionsChris Robinson2012-08-132-0/+56
|
* Don't unlock the pulseaudio mainloop when mixingChris Robinson2012-08-121-2/+0
| | | | | | Lock contention could cause a lengthy delay between mixing and writing the audio. There shouldn't be any risk of dead-locking as the device lock should never be held when the mainloop gets locked.
* Handle the scalar values a bit betterChris Robinson2012-08-112-6/+6
|
* Use a more efficient method to blend HRTF delays and coefficientsChris Robinson2012-08-111-26/+42
|
* Add an option for wide stereo sourcesChris Robinson2012-08-092-2/+18
| | | | Replaces the old stereodup option

|
* Interpolate between HRTF delay samples using the delay fractionChris Robinson2012-07-202-12/+20
