I have a digital voice recorder (Olympus WS852) and I often put the recorder into my shirt pocket as I move around while having a conversation. I would like to reduce the clothes rustle as much as possible without post-processing.
I have come across products like the URSA foamies for external mics, and I don't understand the mechanics of how clothes rustle is made to be able to decide if a foamie 'sock' over my DVR mics would help.
What macgyver solutions have people used to successfully reduce clothes rustle?
