hoa-light object share the speaker definition

[chikashimiyama]

Speaker definition object holds the information of speaker setup. This object is currently only used for vbap but this can be theoretically used also by the hoa-light object

I imagine this may involve changes to the vbap code which allow for exporting and reading the speaker array. Maybe this needs to be done via some sort of getter/setter interface?

I thought [define_loudspeakers] object behaves as a source of truth for all vbap objects in the patch so that I don't have to send "define_loudspeakers" messages to all vbap objects (and eventually hoalight objects) but the help file of define_loudspeakers just confuses me.

It looks like the purpose of [define_loudspeakers] object is to tweak the triangle selection.

In other words, how can I associate a [vbap] object and [define_loudspeakers] object properly?
Is that global scope like singleton (then that's a big problem)

I think now I understand how to use [define_loudspeakers] object.

it outputs loudspeaker-matrices when I send a bang to it and vbap object accepts these matrices.
in this way, if I want to tweak the vbap algorithm using ls-triplets or ls-direction I just do it once, because loudspeaker-matrices also contain tweaking.

so sharing the speaker position between vbap and hoalight should be done in another way and probably it doesn't worth the effort.

Yeah, I was imagining that hoalight could use the loudspeaker-matrices output from [define_loudspeakers]. If it's too much work for now, then leave it as other things are more important.
