My microphone is very good without any crackling... try replacing the supplied USB power adaptor as mine was crap and produced a high pitch squeal on the video.
A poor 12v power supply can cause the DC to DC converters inside many dashcams to generate internal noise and distortion which is picked up on the recordings.Did this work for you? I have a high pitched squeal, but it doesn't sound like its from the mic as its much louder. Im yet to try things as I only just found all of my videos had the squeal
