* Add a simple wrapper to call the mixer functionChris Robinson2023-01-043-5/+11

* Simplify handling effect output for spatial effectsChris Robinson2023-01-042-21/+33
| | | | | | | | | | | | Effects are given a 3D ambisonic buffer of the same order as the device, for processing surround sound. Effects that pass input channels to matching output channels as it processes them don't need to mix each input channel to all output channels. At most, an input channel may mix to a different output channel, if the target buffer uses a different channel layout, and need a gain adjustment, if it uses a different scaling. With a 2D output buffer, a number of channels can be skipped altogether.

* Add a method for the input sample delay for the SampleConverterChris Robinson2022-11-122-1/+14
|
* Add preliminary support for 7.1.4 output modesChris Robinson2022-11-032-0/+3
| | | | | | | | 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 the ability to start a voice at a particular timeChris Robinson2022-11-032-8/+42
|
* Handle negative voice positionsChris Robinson2022-11-022-28/+50
| | | | | | 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 Robinson2022-10-301-1/+1
| | | | | | | 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 Robinson2022-10-272-153/+128
|
* Switch back to the FIR256 filter by defaultChris Robinson2022-10-261-1/+1
| | | | | | 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 Robinson2022-10-261-7/+29
| | | | Also better detail the IIR implementation.
* Use the IIR all-pass filter by defaultChris Robinson2022-10-261-1/+1

* Rename a couple functions to clarify their useChris Robinson2022-10-211-13/+13

* Add separate filter options for UHJ encoding and decodingChris Robinson2022-10-213-4/+6
|
* Add an IIR filter option for UHJ encoding/decodingChris Robinson2022-10-213-30/+384
| | | | | | 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.
* Increase sub-sample precision to 16 bitsChris Robinson2022-10-161-1/+1

* Move some comments to a more appropriate placeChris Robinson2022-09-231-32/+32

* Use the correct va_list for the second vsnprintfChris Robinson2022-09-141-1/+1
|
* Use ifstream's wchar_t constructors on WindowsChris Robinson2022-09-121-1/+1
| | | | MinGW seems to have added them a while ago, so that greatly simplifies things.
* Don't pack ambdec coefficientsChris Robinson2022-09-121-4/+3
| | | | | | | | | 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.
