Research Seminar: Matt Barnes

Dual Output Microphones, Dynamic Polar Patterns and Recordist Agency

While immersive mediation continues to grow in popularity, traditional mono and stereophonic recording techniques remain those underpinning the majority of audio production workflows. By incorporating dual-output microphone technology into these practices, capacity exists for nuancing recordist agency in ways not documented in existing literature. Dynamic Polar Pattern Processing also known as “Delta Technique” is introduced as a means to simulate polar patterns changing shape over time. Practice based methodology catalogues affordances made available via the dual-output technology including pedagogical demonstration, “Rear-Output Panning”, “Performance Panning” and microphone modelling. Supporting data is generously provided by contemporary microphone manufacturer, Austrian Audio.


Matt Barnes is a Canberra based recording engineer specialising in acoustic instruments. As a graduate of the Queensland Conservatorium, Matt is currently undertaking research into the use of dual output microphones, technique and recordist agency. Having freelanced globally in studios between New York, Nashville and London, including Abbey Road Studios, Matt is an AES member (Audio Engineering Society) and certified Pro Tools trainer/operator. Matt has attended multiple AES Conventions co-presenting with Professor Samantha Bennett and also participated in a week-long ‘Mix with The Masters’ seminar with all-analogue engineer, Steve Albini in St. Remi, France. Matt currently manages the recording facilities at the Australian National University.
