## What is MARRS?

MARRS (Microphone Array Recording and Reproduction Simulator) provides an interactive, object-based workflow and graphical user interface for localisation prediction and microphone array configuration. It allows the user to predict the perceived positions of multiple sound sources for a given microphone configuration based on psychoacoustic time-level trade-off functions. The tool can also automatically configure suitable microphone arrays for the user’s desired spatial scene in reproduction. Furthermore, MARRS overcomes some of the limitations of existing microphone array simulation tools by considering a microphone height and vertical orientation.
