December 2022 Meeting Notice – Audio Loudness for New Delivery Platforms

Meeting Notice

The next online meeting of the AES Melbourne Section will be held on
Monday 12th December 2022 at 8:30pm – via Zoom. Note later time

Leading US broadcast technologist, and AES TD1008 Document Working Group Chair John Kean will present on the topic of:

AES Development and Promotion of Audio Loudness Techniques

for new audio delivery platforms

The AES Technical Council on Broadcast and Online Delivery (BOD) launched an intensified effort in 2019 to apply audio loudness techniques to audio services used by consumers. The BOD recognized that audio products, be they speech or music streams, podcasts, and even the voice responses from smart devices needed better coordination in terms of perceptual loudness to raise listener satisfaction. This launched a two-year effort to write a new Technical Document on loudness measurement, TD1008. The TD was completed late last year and is now being introduced through an official AES website that will be open to everyone. John will look at the recommendations as well as some innovative techniques for managing the loudness of various music and speech content. He will also show a pre-release glimpse at the new website.
