Multi channel Support

[HomerJau]

Hi x42,

This looks fantastic!

I'm wondering if you have thought of supporting 4 channel audio goniometer? There a a number of quad/multi-channel enthusiasts that are moving to PC based listening that would love to see their music in a goniometer as in the 'old days' they could buy vector scopes for quad (see example below):

If you are not interested I'd be willing to have a hack but to be quite honest I've got no background in technical audio or mathematics so I'd need advice or your thoughts on how to even implement the theory. But you code would be a good start.

Looking at the beginning video, this seems to be level per speaker (not phase like in a goniometer). Regardless of the polarity the display will always move towards the speaker which has a signal (and never away from the speaker beyond the origin).

That probably makes sense since you likely won't find a quad-system that's calibrated to exactly cancel phases in the sweet-spot, and you don't usually have the push/pull approach of opposite speakers like you'll find in ambisonics systems.

What is your use-case?

There is a "surround level 4" plugin in beta (included with meters already). It is similar to the scope in the video: It does however average the signal-level (K/RMS) with optional peak display, but it shows pair-wise correlation of the channels. That strikes me a lot more useful during production.
