Online acoustic recording education using MARRS

Research output: Contribution to journalConference articlepeer-review


This extended abstract first discusses the importance of teaching and learning spatial audio psychoacoustic principles in acoustic sound recording education. Then it introduces an interactive Web Audio application named MARRS for Web, which has been used for the online teaching of a spatial recording module at the University of Huddersfield during the pandemic period. MARRS (Microphone Array Recording and Reproduction Simulator) provides an interactive visualization of the perceived image position of sound source as the user changes the position and configuration of microphones. The Web version of MARRS also provides a stereo and binaural playback of a virtual quartet with the user's chosen sound files and room impulse responses. The tool has been found highly useful not only for teachers to explain theoretical principles of stereophonic imaging in stereo microphone array recording, but also for students to have a critical listening training with respect to spatial audio attributes and ultimately design their own microphone configuration for desired spatial imaging characteristics.
