A web-based interactive tool that facilitates microphone array design and phantom image prediction is presented within this brief. Originally a mobile app, this web version of MARRS (Microphone Array Recording and Reproduction Simulator) provides greater accessibility through most web browsers and further functionality for establishing the optimal microphone array for a desired spatial scene. In addition to its novel psychoacoustic algorithm based on interchannel time-level trade-offs for arbitrary loudspeaker angles, another main feature allows demonstration of the phantom image scene through virtual loudspeaker rendering and room simulation via the Web Audio API. The current version of the MARRS web app is available through the Resources section of the APL Website: http://www.hud.ac.uk/apl
