Support for arbitrary speaker layouts

[jcelerier]

Hello!

The documentation here mentions only a very specific and narrow set of supported speaker configurations:
https://github.com/videolabs/libspatialaudio/blob/master/docs/RendererOverview.md

Is there a way to set-up the renderer with custom immersive loudspeaker configurations?

For instance at the SAT there's a full-dome setup (works fine with VBAP) + an immersive square black box for which we mainly use SpatGRIS's MBAP (https://gris.musique.umontreal.ca/). DBAP is also an option.

If it's not the case, would you be interested in a PR to add support for a renderer for custom configurations?

Thanks for this library and happy holidays!

Yes.

You need to modify the code, I think.

Of course, this is welcome.
Be careful that the internal HOA renderer is a Regular Dodecahedron, (see the technical report for the reasoning)
