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.

Preliminary Meeting Notice – February 2022

Our first meeting for 2022 is scheduled for Mon 14th February, and it will again be via Zoom.

We will be honoured to welcome Merlijn Van Veen, Senior Technical Support & Education Specialist of Meyer Sound, who will be joining us from the Netherlands.


Merlijn is also Chair of the AES Standards Task Group SC-04-03-A, which has been tasked with developing a new standard X250/AES75 “AES standard for acoustics – Measuring loudspeaker maximum linear sound levels using noise”.

Merlijn will be giving us an overview of that work, and in particular a preview of a new test signal under consideration.


Merlijn’s presentation should be an excellent follow up to Michail’s December presentation on Loudspeaker power ratings.
