Webinar: A Practical History and Review of Audio Codecs for Broadcast

The DTV Audio Group and Sports Video Group will present a Webinar on Wednesday, March 26 at 12:00 p.m. ET, entitled “A Practical History and Review of Audio Codecs for Broadcast“. The webinar will feature an introduction by NBC Olympics SVP/CTO Dave Mazza and a presentation by Tim Carroll, founder of Linear Acoustic, is the CTO of the Telos Alliance.


Codecs for telephony stretch far back into the last century and, though 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 we 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 be time for Q&A.
