[hoa-staging] Use stereo audio files for convolver. about omnitone

[drewbitllama]

that can work. i think we should re-visit the original implementation once >8 channel count files are allowed.

I think this issue is orthogonal to the multichannel audio file issue. If we stick to the stereo files, it actually ensures the cross-browser support because all the browsers (including mobile ones) can decode it.

Can we have the original multichannel HRIR files (FOA, SOA, HOA) in our src/resources? Then I can write a script that generates a set of stereo files from the source.

Sure. They should all be there already.

First of all, what's happening in Chrome M62 when you load up 112 audio files via XHR:

Chrome fires up 12 background threads to multiple decode files concurrently. So this means loading multiple stereo files instead of a big chunk of multichannel HRIR files would be better. With that said, there will be a very little improvement because the size of HRIR files is almost negligible.

The next example loads up ~1500 audio files. Chrome's still using 12 threads to decode. Just for fun.

Secondly, this is what I would do in V1:

1. Use SOX to split up the original HRIR files into multiple stereo files.
2. Include SOX script in the repo for the CI testing.
3. Change the hoa-convolver code to use a set of stereo HRIR files without splitting/cloning buffers.
