Subject: [PATCH] Use a two channel script processor even for mono recordings

This is a difficult thing to explain, but basically if you have an
interface containing multiple input channels and you record in stereo
on only one of the channels, the script processor node will mix down
the channels to mono, and the resulting signal level will be cut in
half.
