Word of advice, stay away from old Impossible Project film stock from Barnes and Noble. Something funky is happening with my sound too. Will do a new stock of color film and hopefully less choppy audio soon. The camera is a Polaroid Close-up with 600 film. I'm not sure if the focus is off, my hands are too shaky or it's the quality of the film or all of the above. Microphone is Tascam DR-05. Maybe formatting the memory card will help. Suggestions appreciated!
