Hey all,

So I'm still scratching my head with controlling audio panning in an x,y grid using 4 speakers.

What, at first, seemed like a somewhat trivial problem, upon closer inspection ain't necessarily so.

Does anyone have examples of panning with 4 speakers? About the only things I have found so far are:
Building upon Hans' [pan_core~]
[pan_quad~] from 'nSLAM', which seems to be unavailable for d/l
The 'pd-tutorial' patch 3-9-3-1-spatial-quadro.pd

Anyone know about any others?

My stereo panning is built upon the square root example in Andy Farnell's book, which I'm really happy with. Ideally I would like to expand upon that.

Then of course there is the whole vbap/ambisonics/cubemixer (possible overkill) route too. My concerns before diving into this are threefold.
1. If it's only going to work for the 2 people in the 'sweet-spot' then what's the point? If it makes any difference I'm using some Bose 180 degrees radiating speakers.

2. The piece is for a performer with electronics, with only the electronics coming out of the speakers. So I'm also wondering whether a 5.1 type setup with the performer as the front centre speaker (as such), may be preferable?

3. The piece requires 96 separate pan positions - how cpu intensive is that going to be? It currently works fine in stereo, which is why 2 lots of stereo in an x,y fashion seems initially preferable.

I'm aware that it's pretty much impossible with this speaker setup to make everyone in the room have a similar audio experience, and also to map my visual masses from an msd swarm in the GEM window as audible points, but surely it is possible to do this as an x,y grid.

I also admit that I don't understand the dsp theory necessary to make the x,y, grid idea happen so if anyone has some pointers regarding that I would be delighted.

Cheers,

Jb
