* Use a unique_ptr to hold raw byte memoryChris Robinson2021-06-211-2/+4

* Fix getting of device channel count in CoreAudio backendalexey.lysiuk2021-06-211-3/+1
| | | | | | | AudioBufferList contains a variable length array of mNumberBuffers elements, so it should not be created with the default constructor like usual class instances. Unfortunately, Apple developer site documentation is literally empty for this API. There is a bunch of comments in framework's header files. Here is the correct usage of AudioBufferList pointer from Chromium: https://chromium.googlesource.com/chromium/src/media/+/008a1abc573e1f8bcf513b50ce48a923b30ef130/audio/mac/audio_manager_mac.cc#266 There were occasional crashes because of memory corruption which was confirmed by address sanitizer

* Set the JACK output ports as terminalChris Robinson2021-06-121-1/+1
| | | | Since there are no input ports associated with the output.

* Improve name duplication handling with JACKChris Robinson2021-06-101-26/+63
| | | | | If a custom device pattern matches an existing one, its name will be replaced. A separate loop is used to check and handle duplicate display names.
* Add an option to mix directly in the JACK callbackChris Robinson2021-06-082-69/+144
|
* Handle the listener position separate from the rotation matrixChris Robinson2021-05-252-12/+10
| | | | | | It's too unstable with larger vectors. Even when the source and listener positions are the same, floating point precision can cause noticeable rounding errors.

|
* Partially implement an extension to hold sources on disconnectChris Robinson2021-04-265-1/+22
| | | | | | | | Rather than stopping voices/sources when the device becomes disconnected, the context can be set to leave them alone. As a consequence, their state will remain as playing and they'll keep their last known sample offset indefinately. For applications mindful of this behavior, it will allow resetting or reopening the device to reconnect and automatically resume where it left off.

* Create a base the ALCdevice and ALCcontext structsChris Robinson2021-04-2422-263/+298
| | | | | A base that contains the API-agnostic data, with ALCdevice and ALCcontext being for AL-specific data.
* Move some more sources to coreChris Robinson2021-04-245-469/+2
|
* Use the root mean square for the HRTF B-Format HF scaleChris Robinson2021-04-241-1/+3
| | | | | | | | For the second-order decoder. Since the delays are adjusted to avoid most high frequency phase cancelation, the energy-based scaling with the number of channels used creates a significant HF increase. Using the RMS-based scaling seems to create a more level response, though it's not perfect either. More testing and measurements may be needed.

| | | | If pthread_setschedparam fails or is unavailable.
* Make an inverted atomic flag type and use itChris Robinson2021-04-152-7/+7
| | | | | | | | The inverted atomic flag replaces test_and_set+clear with test_and_clear+set, essentially inverting the flag status. This makes more logical sense for flagging dirty state, which is less confusing than flagging clean state. The one caveat is ATOMIC_FLAG_INIT (or default construction in C++20) initializes the state to true rather than false.
* Use per-HRIR delay alignment for B-Format-to-HRTFChris Robinson2021-04-091-6/+11
| | | | | | | | | | | | | For HOA signals, the number of responses used with slightly varying delays causes noticeable attenuation in the higher frequencies because of destructive phase interference. This is not a result of minimum phase alignment (attempts to compensate for minimum phase had negligible results), nor does it affect first-order signals (which only has 4 unique responses on each side). This alternate alignment is only used when doing second-order rendering for HRTF output, which is not the default with HRTF. It's likely not very ideal, but it's necessary to prevent second-order rendering with HRTF from sounding muffled.
