Another thing I'm learning about are these two discs. Any experience with these and word talking about? Core Sound — Jecklin Disk and Schneider Disk microphone mounts They look like they would be simple to make. Is part of the science around stereo recording to create a human POV made this simple. The foam disc acts like your head and the mics are your ears. Obviously more to it than this when we are dealing with reflections and room but wow, Never thought about it quite like this.
