* Make the source state atomicChris Robinson2017-02-135-34/+36
| | | | | Since it's modified by the mixer when playback is ended, a plain struct member isn't safe.
* Put BsincState in a generic unionChris Robinson2017-02-1311-77/+81
|
* Porperly check for and use __builtin_assume_alignedChris Robinson2017-02-134-12/+36
|
* Clean up the bsinc mixer a bitChris Robinson2017-02-123-26/+28
|
* Add NEON-enhanced resamplersChris Robinson2017-02-123-4/+294
|
* Print separate messages for building sdl_sound and ffmpeg examplesChris Robinson2017-02-121-3/+3
|
* Don't require SDL_sound for alffplayChris Robinson2017-02-112-49/+64
| | | | Also explicitly link with libz for alffplay, since static ffmpeg libs need it.
* Fix more uses of unsigned sizes and offsetsChris Robinson2017-02-103-10/+10
|
* Remove a couple context lock wrapper functionsChris Robinson2017-02-073-26/+17
|
* Properly capitalize NEONChris Robinson2017-02-071-1/+1
|
* Clear trailing whitespace from the cpu features stringChris Robinson2017-02-071-0/+5
|
* Use the correct IID for the opensl buffer queueChris Robinson2017-02-071-2/+3
|
* Convert the OpenSL backend to the new backend APIChris Robinson2017-02-073-177/+434
| | | | | This also removes the buffer queue callback's call to aluMixData, which could potentially block on a mutex.
* Fix for NULL JNIEnvChris Robinson2017-02-052-5/+9
| | | | Which can happen with native-only apps
* Call getSystemService as a non-static functionChris Robinson2017-02-031-4/+4
|
* Android's AudioManager.getProperty(String) returns a StringChris Robinson2017-02-021-1/+1
|
* Replace more ALuint with ALsizeiChris Robinson2017-01-293-15/+15
|
* Fix late reverb low-pass filteringChris Robinson2017-01-291-1/+1
|
* Use an all-pass series on each late reverb lineChris Robinson2017-01-281-261/+396
| | | | | | | | | This attempts to improve the smoothness of the late reverb decay by passing each line through multiple all-pass filters. Some work is still needed to work better in high-density and not-so-high-diffusion environments. This also removes the decay from the early reflections, since it's no longer continuous feedback.
* Add more traces for the Java calls being madeChris Robinson2017-01-271-7/+22
|
* Remove __android_log_print calls for TRACEREFChris Robinson2017-01-271-1/+0
| | | | | TRACEREFs aren't normally important, and for as often as it happens, the added function calls are wasteful even if they end up doing nothing.
* Round and clamp the scaled update count with openslChris Robinson2017-01-271-1/+4
|
* Try to use the system sample rate with AndroidChris Robinson2017-01-261-6/+56
|
* Also log to __android_log_print on AndroidChris Robinson2017-01-262-0/+18
|
* Get the JavaVM handle on Android targetsChris Robinson2017-01-262-0/+72
|
* Improve the ambisonic upscaling methodsChris Robinson2017-01-243-129/+174
| | | | | | | | This now takes advantage of the differences seen in generated decoder matrices for first-order compared to second- and third-order, such that with the appropriate frequency-dependent scaling applied to first-order content, the result is identical with a higher-order decoder matrix compared to a first- order matrix for the same layout.
* Fix coefficient counts for the built-in B-Format decodersChris Robinson2017-01-211-2/+2
|
* Use a flat sqrt(2) scale for non-directional ambient gainsChris Robinson2017-01-211-8/+3
|
* Update the default basic B-Format decodersChris Robinson2017-01-211-47/+36
| | | | This also converts them to ACN/N3D format.
* Move the B-Format HRTF virtual speaker stuff to InitHrtfPanningChris Robinson2017-01-184-100/+96
| | | | | This keeps the decoder matrices and coefficient mapping together for if it changes in the future.
* Replace some ALvoid with voidChris Robinson2017-01-183-6/+6
|
* Use ALsizei in more placesChris Robinson2017-01-1811-94/+94
|
* Pass the left and right buffers to the hrtf mixers directlyChris Robinson2017-01-175-37/+41
|
* Small update for the "virtual" Ambi2DDecoder coefficientsChris Robinson2017-01-171-5/+5
|
* More ALsizei, with the B-Format decoderChris Robinson2017-01-165-26/+35
|
* Fix a couple hard-coded array sizesChris Robinson2017-01-161-2/+2
|
* Use ALsizei in a few more placesChris Robinson2017-01-164-9/+9
|
* Use ALsizei and ALint for sizes and offsets with resamplers and filtersChris Robinson2017-01-1610-75/+76
|
* Use ALsizei for sizes and offsets with the mixerChris Robinson2017-01-1612-189/+189
| | | | | | Unsigned 32-bit offsets actually have some potential overhead on 64-bit targets for pointer/array accesses due to rules on integer wrapping. No idea how much impact it has in practice, but it's nice to be correct about it.
* Use second-order ambisonics for basic HRTF renderingChris Robinson2017-01-156-25/+95
| | | | | | This should improve positional quality for relatively low cost. Full HRTF rendering still only uses first-order since the only use of the dry buffer there is for first-order content (B-Format buffers, effects).
* Replace range-based for loops with QList iteratorsChris Robinson2017-01-131-8/+8
| | | | Less than ideal, but some targets can't rely on C++11
* Search for and use Qt5 for alsoft-configChris Robinson2017-01-121-13/+36
| | | | An option is provided to instead use Qt4.8 still if desired.
* Use C++11 for alsoft-configChris Robinson2017-01-122-8/+14
|
* Update binary search algorithm for uintmapsChris Robinson2017-01-121-68/+79
|
* Avoid using some LP typesChris Robinson2017-01-101-5/+5
|
* Use proper atomics in the OSS backendChris Robinson2017-01-101-17/+17
|
* Hold Pulse's mainloop lock while calling capture functionsChris Robinson2017-01-101-2/+10
| | | | | | | Since commit c837484015e, the backend's lock is no longer implicitly held when calling capture functions. A separate mutex is used to ensure serial access, and its up to the backend to protect against races and reentrancy with the audio API.
* One more update for the HRTF B-Format coefficientsChris Robinson2017-01-091-14/+14
| | | | These should better represent the pseudo-inverse matrices with N3D scaling.
* Add missing AL_EFFECTSLOT_ properties for al(c)GetEnumValueChris Robinson2017-01-051-0/+5
|
* Update the B-Format HRTF coefficients to use the pseudo-inverse matrixChris Robinson2017-01-041-26/+14
| | | | | | It's hard to tell which is ultimately better, although this way does make the FOA output somewhat louder which will help when it's combined with direct HRTF rendering.
