This 45-minute webinar will be presented by Telos Alliance CTO and Linear Acoustic founder Tim Carroll.
Tim 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?
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.
Tim's presentation will be introduced by Dave Mazza, NBC Olympics, SVP/CTO. There will be time for Q&A.
