Sorry to pivot guys, I'm trying to find a solution for recording surround s=
ound for Virtual Reality and while at first it seemed like binaural was the=
 way to go, it now appears that I need to record in 5.0/5.1 and then encode=
 the audio with the Fraunhofer Cingo codec into an MP4. Does anyone have a =
suggestion for a small but high quality system that produces 5.0/5.1? Also,=
 what do I need in order to edit 5.0/5.1? I'm currently using Adobe Soundbo=
oth but I don't think that'll do the trick anymore.

Thanks for your thoughts :)

Eric
