In view of the previously stated point that lecturers adjust their own micr= ophone levels to ensure they can be heard, you will probably want to pick u= p the audio at some point after where they adjust the level, as this is lik= ely to give the best consistency in recorded audio level (although you may = also require some form of automatic level control to handle extra loud peri= ods when the lecturer may get exasperated or whatever). --=20 Scanned by iCritical. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
