* 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

* Rename a couple functions to clarify their useChris Robinson2022-10-211-13/+13
|
* Add separate filter options for UHJ encoding and decodingChris Robinson2022-10-216-18/+49
|
* 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.

* Update the built-in quad and 7.1 decodersChris Robinson2022-09-161-26/+26
| | | | | Make them first- and second-order respectively. They don't have enough speakers to really be suitable for higher orders than that.

* Use ifstream's wchar_t constructors on WindowsChris Robinson2022-09-123-173/+20
| | | | MinGW seems to have added them a while ago, so that greatly simplifies things.
* Don't pack ambdec coefficientsChris Robinson2022-09-122-68/+25
| | | | | | | | | Tne coefficients are placed as for full 3D ACN handling. The ChanMask just indicates which have potentially useful values. This could be a bit more agressive and clear ChanMask bits for channels that don't contribute to output, so that a decoder the specifies height-related channel bits, but leaves their coefficients all 0, can be handled as 2D. I don't expect many ambdec files to be like that, though.
