You can record for over 12 hours in mono at 22,050Hz if you need for it to last that long, and it is quite good quality.

Rob >>> rftb@xxxxxxxxxxxxx 10/01/07 12:10PM >>> This may be a very basic question, but I wasn't sure how to answer it when it was asked of me. Should we be using stereo mode when recording audio books using Studio Recorder? If so, wouldn't we need to use more than one microphone to make the recording "stereo"? I recorded a sample in mono, and then in stereo, and they didn't sound any different from each other. Thanks for any advice anyone can offer! Doreen Murphy
