[Euan de Kock]

Hi All,

I'd prefer if we keep the audio in stereo too. I try and pan the
audience mic slightly away from centre to give some separation between
the two which give a hint as to who is speaking, and once we start
adding in reverb etc effects we will definitely benefit with having the
signal in stereo.

Regards,

Euan.
