3d downmix / 'object audio' infrastructure?

[David Holroyd]

Hi,

Does anyone know of gstreamer infrastructure to help placing an input 
(mono) audio source in 3D space, and then rendering a downmix to stereo 
and/or a standard surround layout?

FWIW, I'm specifically interested in being able to 'pan' audio around 
the listener, and am wondering how much effort I can save vs needing to 
write a specific downmix for every output audio channel configuration 
that might be required.

Maybe there is a surround layout that is 'easy' to render (no low 
frequency channels!), and then audioconvert can produce stereo from that 
if required?  A well tested, off the shelf solution is even nicer of 
course ;)


Many thanks!
