Meeting Report: June 2022 – DaS AuReality demonstration

On Monday 20th June the AES Melbourne Section finally returned to our old meeting haunt of the SAE Institute lecture theatre, where we welcomed Vastigo’s Joe Hayes to demonstrate his DaS (Diffusion at Source) AuReality loudspeakers.

In October last year, Joe introduced us to his concept of the DaS loudspeaker algorithm which provides a listening experience unshackled from the room’s acoustics and free of sweet-spot limitations. A full report on that presentation can be found at https://www.aesmelbourne.org.au/mtg-rpt-oct2021/

This time around, Joe gave us the opportunity to hear the results of his work.

Meeting Report: April 2022 – Involve Audio Demonstration

With COVID restrictions significantly eased, the Committee has made the decision to trial some in-person events as well as to maintain some online events for the 2022 meeting calendar.

On Monday April 11th a small cohort gathered in person for the first time in over two years for a Section Meeting. We visited the Involve Audio facility at Mentone, where Charlie Van Dongen demonstrated his designs for the complete surround sound chain with improved soundstage imaging – decoding, amplifier, loudspeaker processing, as well as electrostatic loudspeakers.
