True - but they are ones that work and are well established.

Ambisonics and WFS are well-established?! Depends on your view on this...
In the sense that the technology is well developed and that there are an increasing number of
applications of both, though, I would agree, not in a mass market (yet)
It also sounds as if Ambisonics and WFS don't have some drawbacks, and of course both systems
have some.
Indeed they have drawbacks - engineering is like that, always about making compromises, good
engineering is about attempting to make optimal compromises. :-)
You "review" a system (SRS, CC3D) you even don't know enough, and obviously in a negative ("snake
oil") way. IMO they are trying to develop a system which covers some demand from outside.
"Cinema" is in the name of CC3D. Even if they are copying some elements from elsewhere, I think
this is still ok. There seem to be some new aspects. On a system level, you can't say SRS is
copying anything else, because there is no established parametric/object-based 3D audio system
elsewhere which they could copy.
Sorry, but their blurb reads like snake oil sales talk so I called it that. It wasn't a comment on
the system - since I haven't heard it and have no technical information to go on, I couldn't do so.
It would, of course, not be unknown for companies who want to keep IP secret to deliberately
obfuscate things....
Hmm, reading through this, it seems that basically they've discovered MPEG4 Spatial Audio Object
Coding :-)
Was this about 3D audio? Doubt this... And anyway, outside from academic research nobody has
implemented this.
I'm not sure about that.
For my part, I will try to get more information about this. However, I could imagine why SRS won't
discuss their system on this list.
Look forward to hearing all about it...
Dave
