DTV Audio Group free webinar on audio codecs for broadcast scheduled for 26 March

Presented by Sports Video Group, A Practical History and Review of Audio Codecs for Broadcast will be presented by Linear Acoustic founder and Telos Alliance CTO Tim Carroll and feature an introduction by NBC Olympics SVP/CTO Dave Mazza. Proficiency in mathematics is not required for the 45-minute session, which commences at 12.00pm EDT on Wednesday 26 March.

Codecs for telephony stretch far back into the last century and, although the quality was very different, the goals were essentially the same: getting more audio channels through restricted pipes. For signals that contained speech and music, even better codecs were required and began to appear on the scene even before digital signal processing (DSP) was small enough, fast enough, or cheap enough. Once DSP started to become mainstream, codec efficiency and performance began to climb exponentially. Multichannel audio, initially driven by film, rapidly expanded into the consumer space raising the bar further. Today the broadcast industry relies on codecs in many known and unknown parts of the chain. It is facing new requirements to deliver many channels of audio across many distribution channels to myriad consumer devices being enjoyed in environments of all shapes and sizes.

In this 45-minute webinar, Carroll will review the history and progress of audio codec technology, as well as exploring why codecs are still required and what they will be asked to do in the future. Can codecs continue to help balance the desire for “more” with the goal of “better”? How might this impact the broadcaster and the consumer? There will also be time for a Q&A.
