* 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 Robinson2012-08-1818-22/+62
| | | | | 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 Robinson2012-08-183-0/+116
| | | | | 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 Robinson2012-08-1717-15/+165
| | | | | 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 Robinson2012-08-162-5/+5
|
* Remove extra parenthesis used in the aligned attribute declarationChris Robinson2012-08-161-2/+2
|
* Fix aligned allocator fallbackChris Robinson2012-08-161-3/+2
|
* MSVC wants __declspec(align), not __declspec(aligned)Chris Robinson2012-08-161-1/+1
|
* Avoid dynamic handling of libsndioChris Robinson2012-08-162-88/+3
| | | | This makes it safer and easier to handle as OpenBSD updates it
* Apply HRTF mixer coefficients with stepping using SSEChris Robinson2012-08-154-11/+65
|
* Check the max CPUID functions before calling themChris Robinson2012-08-151-4/+11
|
* Make sure sources are 16-byte alignedChris Robinson2012-08-151-4/+4
| | | | | They contain fields that require 16-byte alignment for SSE (and Neon?) acceleration.
* Add wrapper methods to ensure aligned allocationsChris Robinson2012-08-154-0/+65
|
* Ensure some HRTF-related parameters are alignedChris Robinson2012-08-151-4/+4
|
* Make sure the working coefficients are aligned for the SSE mixerChris Robinson2012-08-154-6/+12
|
* Remove unused filter functionsChris Robinson2012-08-151-21/+0
|
* Check for and use the -msse switch when dealing with SSE intrinsicsChris Robinson2012-08-151-1/+11
|
* Check the correct macro for ARM Neon supportChris Robinson2012-08-151-1/+1
|
* Don't bother handling MMX since we don't use itChris Robinson2012-08-152-13/+5
|
* Add cmake options to disable or require support for CPU extensionsChris Robinson2012-08-154-15/+48
|
* Move mixers into separate source filesChris Robinson2012-08-157-419/+617
|
* Add an SSE-enhanced HRTF mixer using intrinsicsChris Robinson2012-08-145-3/+57
| | | | Not as good as it could be, but it's something
* Fix a typoChris Robinson2012-08-131-1/+1
|
* Add a config option to disable use of CPU extensionsChris Robinson2012-08-134-10/+52
|
* Allow building multiple types of mixers, selecting based on CPU capsChris Robinson2012-08-131-47/+64
|
* Check for some CPU extensionsChris Robinson2012-08-135-0/+71
|
* 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 Robinson2012-08-094-2/+29
| | | | Replaces the old stereodup option
* Use a more efficient method to offset the speaker angles when computing gainsChris Robinson2012-08-091-29/+35
|
* Interpolate between HRTF delay samples using the delay fractionChris Robinson2012-07-203-12/+23
|
* Increase the directional change sensitivity for the HRTF deltaChris Robinson2012-07-201-1/+1
|
* Fix an inadvertent change in the HRTF coefficient stepping value array sizeChris Robinson2012-07-191-1/+1
|
* Use wrappers for float-typed math functionsChris Robinson2012-06-2910-105/+94
|
* Test the squared length of a vector before normalizingChris Robinson2012-06-281-8/+6
|
* Minor typo fixesChris Robinson2012-06-281-2/+2
|
* Don't use all caps for enum value namesChris Robinson2012-06-2815-205/+205
|
* Don't try to set FE_TOWARDZERO when it's not availableChris Robinson2012-06-281-0/+2

* Use a proper method to wait for a PulseAudio operationChris Robinson2012-06-191-18/+19
|
* Remove an unused includeChris Robinson2012-06-191-3/+0
