About the Event

The evening’s presentation will consist of two portions exploring various aspects of digital audio standards and their practical implications to all audio practitioners regardless of whether they are involved in recording or live production. For over 2 decades the mandate of the industry has been to achieve higher sample and bit rates and now that we can work at 192 kHz the question is whether the clients need it, appreciate it and the constant issue of the cost of the increased performance.

The first half of the evening will be given by Michael Nunan…  “I’m not sure there’s anyone left who would vigorously (or otherwise) argue with the merits of high sampling rates… but a useful starting point for a ‘deep dive’ into the fine detail of high fidelity detail is perhaps to take an agonizingly pragmatic look at the realities of working above 48/24.”

With large-scale Broadcast and Music-for-Picture as the framework, Michael will start the evening with a brief discussion about the practicalities of unilaterally moving into high sample rate work.

The second half of the evening will be a unique ‘ears on’ demonstration staged by Donny Chow, President and Chief Engineer of Xilica Audio who are located in Stouffville, ON.

Over the last 27 years Donny has committed to creating product that exceeds that standard of which most digital audio possessors are built to. His usage of unique floating point algorithms as opposed to fixed point architecture is credited for Xilica products reputation for sounding tangibly better than other products that are based on fine-tuned performance optimized DSP algorithms.

A rare opportunity for attendees will come in the form of demonstrating 24 bit comparisons to 40 bit processing, 48kHz vs. 96kHz and fixed and floating point architectures. Our industry bandies about statistics on performance almost casually and this evening’s presentation will be a rare opportunity to actually hear what those numbers sonically represent in the final product.

Floating point.
There are a couple of paragraphs relating to fixed point vs floating point. This is a chip manufacturer so most of the info is irrelevant to our meeting topic.
