I'm going to be doing some recording tonight using a Zoom H4 as the interface for Audacity. I've laid down a scratch track in stereo. My question, should I record the other tracks (banjo, guitar, vocals) in stereo or mono. I'm using the built in Zoom mic which is stereo, but I'm not sure there is really much difference whether or not I record in stereo or just mono, panned in the middle. The stereo tracks of course take up double the space. Any advice?
