This is an audio test of the Sony ICDPX312 Digital Voice Recorder, and normal video camera (H106) in a fixed location. The audio quality is very good and another unit attached to the interviewer would have been an added plus. The Sony ICDPX312 Digital Voice Recorder has a very good internal (stereo) microphone, and if hidden would probably do very well for both subjects. Check my other test at: www.youtube.com
