A production work flow optimized multichannel virtual reality microphone that has its own rendering software allowing for the recording, rendering, and playing back of immersive, head-trackable positional audio for 360 video, gaming, and virtual reality applications. The multichannel microphone used to record multiple binaural sound perspectives, has eight microphones coupled to a rotatable disc frictionally mounted on the outside of a truncated spherical shell, an internal, detachable clamp for attaching the shell to a vertical pole stand, and easily accessible microphone output connections configured as four stereo microphone pairs, spaced closely to an average set of human ears. The microphone output connections are located on an internal support member. These are accessible through upper and lower lids and a door. Four small baffles simulating the pinna of the human ear reside on the disc, separating the paired microphones.
