Re: [Sursound] about principled rendering of ambisonic to binaural

[David McKevy]

Ralph you mentioned wanting a Mac based VST so I assume you have access to
Logic and can try their binaural decoder?

It's been a while since I worked with channel based surround but I assume
that by now they may have varying HRTF's...

Just a thought...

Re: [Sursound] good 3d sound outdoors

[David McKevy]

Check out Henry Brant’s thoughts on this. Each instrument is a speaker in
his mind... and outdoors, site specific was a special niche of his.

Re: [Sursound] build in speakers

[David McKevy]

Hi Soren
My 2 cents:
-shouldn't be a problem embedding a wooden speaker encasement with speaker,
inside pretend stone jutting out from your wall here and there?
Jutting out effect is made with paper mache or plaster of Paris covering
the speaker box... and have the front (the part of the speaker the audience
may see) covered with speaker cloth..
You may want to stain or change the color of the cloth so obviously acrylic
won't do for that, or anything that may stiffen that fabric, so stain it
with dye (i.e. dye for tie-dye) if must discolor it.
-you can play with using the stone backdrop as the rear of the speaker, so
that the speaker with casing is fixed to the fake wall, (so, before the
speaker with casing is fixed to it, the back of it is open  to reduce
weight and strain on your wall.
And here is where you'd have to trouble shoot the acoustics way more than
the speaker cloth covering it for visual aesthetic.
-embed speaker stands in the wall like how rebar is embedded in concrete in
construction

Yes for azimuth planner!
