DarkIce next version
o added possibility to stream in mono even when recording in stereo,
thus enabling mono and stereo streams with the same darkice instance.
only for mp3 streams at the moment
thanks to Kai Krakow <kai@kaishome.de>
o bug fix: resampling audio for vorbis streams bugs fixed
02-08-2002: DarkIce 0.10.1 released
