I have tried several microphones and find the RODE VIDEOMICRO works the best but there is still a background "rolling click" noise that I can only desribe as the noise you get from old school film projector, I cant get rid of. This is in regards to the sound taken from the MicroSD card not the control device, has anyone else here had this issue and if so did you find a fix?

Running most current FW and APP. using iPhone6+ and Lexar 1000x microsd

Hi Cale, could you please upload the original video file to dropbox and send me the link?
