* Add GitHub actions workflow to build utils/makemhr on update (#783)3DJ2022-11-161-0/+76
| | | | | | | | * Build utils/makemhr on update This workflow builds makemhr.exe including dependencies (libmysofa, zlib, etc) whenever anything under utils/makemhr or the workflow is updated. It also uploads artifacts and [(pre)releases it with its own tag](https://github.com/ThreeDeeJay/openal-soft/releases/tag/makemhr) for a [permanent, up-to-date download link](https://github.com/ThreeDeeJay/openal-soft/releases/download/makemhr/makemhr.zip). * Clone latest libmysofa release tag without history
* Fix router not loading on Creative's hardware OpenAL (#773)Felipe2022-11-161-12/+22
| | | | | | | | | | | | | | | According to the programming guide and the specification, those functions may be used by extensions. However, Creative's hardware OpenAL chose to not implement stub functions for those that they do not use. Currently they use only alBufferi for X-RAM related functions. Other implementations, such as OpenAL Soft and wrap_oal implement stub functions for those methods therefore they work. This commit turns those functions optional, just like they were in the old FOSS router. Consumers of the router will receive a nullptr as expected for not implemented methods if they load them using alGetProcAddress, which I believe is the correct way to do so. That is, the context must be current before loading al* functions.
* Avoid a use-after-free in the ALSA backendChris Robinson2022-11-161-12/+12

* Use SDL2's sdl2-config.cmakeChris Robinson2022-11-162-199/+11
| | | | Instead of our own custom FindSDL2.cmake
* Avoid unnecessary duplicate CMake variablesChris Robinson2022-11-162-11/+2
| | | | | This should make FindPulseAudio.cmake more compatible with PulseAudio's own PulseAudioConfig.cmake.
* Use the correct frame size for WASAPI resamplingChris Robinson2022-11-131-2/+2
|
* Avoid a potential unsigned underflowChris Robinson2022-11-131-1/+1

* Change a function to a static methodChris Robinson2022-11-134-9/+9

* Avoid duplicate checks and calculationsChris Robinson2022-11-131-12/+8

* Add a config option to prevent WASAPI from using a resamplerChris Robinson2022-11-122-1/+13
|
* Add a resampler to WASAPI outputChris Robinson2022-11-121-10/+75
| | | | | | | This allows mixing at various samples rates that WASAPI doesn't otherwise support. This is mostly helpful for users that have unnecessarily high device rates (96 or 192khz), and lets the ALC_FREQUENCY attribute or frequency config option set a lower mixing rate for more efficient processing.
* Fix SampleConverter source read countChris Robinson2022-11-122-47/+23

* Add a method for the input sample delay for the SampleConverterChris Robinson2022-11-122-1/+14

* Make sure sio_write and sio_read return valid valuesChris Robinson2022-11-071-5/+12
|
* Support different input channel orders in uhjencoderChris Robinson2022-11-041-12/+39
|
* Add preliminary support for 7.1.4 output modesChris Robinson2022-11-0319-6/+201
| | | | | | | | I don't know how different sound APIs handle 7.1.4 ("Atmos" or "Auro3D") output, but currently it simply specifies the additional channels with the height channel labels. This isn't likely how it works for a virtualized channel bed, for playing over other with-height configurations (7.1.2, 5.1.4, etc), but this should be an okay start.
* Add functions to start sources at a particular device timeChris Robinson2022-11-034-161/+247
| | | | | | | | This starts a source at a particular device clock time, rounded to the nearest sample (really, 4th sample for SIMD reasons), allowing to start a sound at a particular point in the output instead of the next update. Unlike using negative offsets, this is not affected by pitch/velocity.
* Add the ability to start a voice at a particular timeChris Robinson2022-11-034-9/+49
|
* int64_t max can't fit into a double without narrowingChris Robinson2022-11-021-6/+0
|
* Handle negative voice positionsChris Robinson2022-11-023-64/+116
| | | | | | This allows a voice/source to start with a delay, more accurately than simply waiting to call alSourcePlay. The delay is affected by pitch and velocity, making it useful to simulate distant sounds that take time to be heard.
* Use the IIR filter for UHJ by defaultChris Robinson2022-10-302-3/+3
| | | | | | | Now that it doesn't cause the distortion like before, the IIR implementation provides a very wide pass-band with the lowest CPU requirements. If maintaining the original phase is important, fir256 and fir512 are still available, given whether lower CPU use or a wider pass-band is more important.
* Rename some variables to more clearly indicate their meaningChris Robinson2022-10-285-40/+40
|
* Rework the UHJ IIR filters to avoid applying an IIR in reverseChris Robinson2022-10-273-155/+130
|
* Switch back to the FIR256 filter by defaultChris Robinson2022-10-262-5/+5
| | | | | | There is a surprisingly noticeable amount of static caused by the IIR filter in particular circumstances. The 256-point filter is only slightly slower, but the frequency response should be good enough to use as a default for now.
* Use the correct input for the IIR UHJ encoderChris Robinson2022-10-262-9/+31
| | | | Also better detail the IIR implementation.
* Use the IIR all-pass filter by defaultChris Robinson2022-10-262-6/+7

* Update upload-artifact to remove warning (#778)3DJ2022-10-231-1/+1
| | | | | | | > Node.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: actions/upload-artifact This should fix 2 of the 3 warnings here: https://github.com/kcat/openal-soft/actions/runs/3303596206 by updating to this https://github.com/actions/upload-artifact/releases/tag/v3.1.1 The third warning is more of a heads up of the macOS runner being updated so it should go away eventually
* Add missing headerChris Robinson2022-10-221-0/+1

|
* Add an IIR filter option for UHJ encoding/decodingChris Robinson2022-10-215-33/+389
| | | | | | This uses the reversed-allpass trick to maintain linear phase. with a 256- sample look-ahead/delay to minimize distortion. This should better preserve low frequencies while maintaining a proper phase response.
