Meeting Notice: “From continuous to discrete and back again”

Meeting Notice:  

The next meeting of the AES Melbourne Section is on Monday 24th November at 7:30pm
at The SAE Institute Lecture Theatre, 235 Normanby Rd South Melbourne.
(directions below).
Mark Edwards will present on the topic:

“From continuous to discrete and back again”
Practical demonstrations of digital audio sampling theory.

This talk will build on last month’s introductory digital topic, with a presentation on the theory and practical aspects of the sampling process used in analogue-digital-analogue conversion.


Under current practices the majority of audio storage and manipulation takes place in the digital domain. The practices used to change the fundamentally continuous sound-waves into a highly accurate discrete digital representation, and back again, rely on the correct application of sampling theory. This makes the topic a core fundamental of modern audio practice.

It is a subject that all audio practitioners need to properly understand – given the bewildering array of choices of technologies, sampling rates and bit depths available today.

Mark will provide a (mostly) non-mathematical treatment of the subject, with an emphasis on demonstrating digital audio sampling theory, aliasing and filtering.

About Mark Edwards:
Mark Edwards has been fascinated by sound since listening to his first cassette player at the age of 8 and has been entranced by cinema sound since a transformative visit to the Odeon in Leicester Square where a THX Cinema Sound System had been installed. He’s always been fond of music and having learned the piano and violin from an early age he took his music schooling into University where he studied Music and Sound Recording at University of Surrey. A career in classical music engineering and production soon followed working as an in-house engineer for mastering and production facility “Chop ’em out”. 

Mark moved to Australia in 1998 and took up a post working for a large digital advertising company and from there went to work for a large software company as a software and infrastructure consultant. However the world of sound beckoned once more and from there he took up freelance work on film and TV projects whilst keeping a hand in the music recording world – particularly in the world of early music opera.

He has worked on Feature Films (Taj, Groomless Bride, Play It Safe) in both production and post-production roles, Short Films (Grey Bull, We Keep On Dancing, Coral), TVC’s, TV Shows (BBC, SBS) and his work has helped lots of directors and producers look and sound great when they are winning their awards at film festivals such as “Palm Springs International Film Festival”, “Melbourne Film Festival”, “Sydney Film Festival”. His work was also been nominated for an ASSG award (We Keep On Dancing – 2013).
