I'm trying to import songs off of CDs that are in mono. I can import them in Banshee or Rhythmbox, but the result is a stereo MP3, and I reason that if the mono songs are in stereo, then they're taking up twice as much space as they should be. The LAME plugin used by default in Rhythmbox and Banshee doesn't allow me to import the songs in mono (or at least if it does, then I don't realize it, and if that's the case then I apologize for wasting everyone's time). Is there some additional plugin I can install to allow LAME to create mono MP3s right in Banshee? I'd rather not manually fold down then re-encode in Audacity.
