Feature Request: Custom DSP for HRIR Processing

[sallliisa]

Less of a feature request and more of a question. Would integrating that feature be possible in the current BackgroundMusic architecture? Like convolving the audio stream with the user's custom HRIR before sending it out to the output.

The only significant thing that comes to mind is that BGMDriver (the virtual audio driver) currently only supports 2-channel audio. So if you wanted to do virtual surround sound and downmix from surround sound to stereo, you'd need to add support for >2 channels in BGMDriver. I wouldn't think that would be that much work, mostly just a lot of small changes.

If you don't need any of Background Music's features and just need a virtual audio driver, you could have a look at Blackhole, which already supports >2 channels.

Also worth looking at #68 (which I've been feeling guilty about not replying to for almost 10 years now).
