Linear Acoustic Founder and President Tim Carroll to Serve as Panelist at AES New York 2007

Acoustic, announced that company president and founder Tim Carroll will
participate as a panelist at AES New York 2007, which runs from Oct. 5 to 8 at


Center. Carroll will join
other audio leaders for three sessions: “Surround Contribution for Radio and
TV,” “Audio for HDTV: Dialnorm,” and “Audio Processing for HD (Radio and TV).”

“Audio processing technologies are clearly a critical part of any broadcaster’s
operations, and the transition toward digital and HD raises a number of issues
for both the television and radio industries,” said Carroll. “I look forward to
relating my own experiences as a contributor to industry standards and
developer of audio processing technologies for digital broadcast.”

The “Surround Contribution for Radio and TV” workshop (W11), scheduled for
Saturday, Oct. 6, from 1 p.m. to 3 p.m., will cover technology that may be used
over various types of networks to enable surround sound contribution for radio
and TV. In addition to a discussion of systems that operate over E1 or T1 and
other synchronous networks, the workshop will address the growing use of
managed private IP networks as the Internet is providing higher bit rates and may
in the future also be capable of supporting surround contribution of
professional audio formats. Carroll and his fellow panelists will discuss the
pros and cons of various solutions and present practical implementations as
case studies.

On Sunday, Oct. 7, from 11 a.m. to 1 p.m., the broadcast session “Audio for
HDTV: Dialnorm” (B11) will feature Carroll along with representatives from
Dolby Laboratories and CBS. Attendees will have the opportunity to discuss the
Dialnorm metadata parameter, one of several designed to help consumers tailor
their audio decoding to a variety of listening environments. A key question
today is how Dialnorm will be effective if content providers don’t agree on how
to set this vital parameter. Several major networks have differing
methodologies for choosing values for distribution to their affiliates, and
there is no consistency at the station level. The panelists will provide
insight into the issue and respond to attendee queries.

“Audio Processing for HD (Radio and TV)” (B13) is scheduled for Sunday, Oct. 7,
from 2 p.m. to 4 p.m., and this broadcast session will explore issues in audio
processing as broadcasters move from analog to digital and into HD. The
broadcasting industry is making a rapid transition to digital, with television
facing an imminent turn-off of analog, and radio possibly looking at a similar
challenge down the road. Though origination and production are well into the
transition, balancing the newfound dynamic range of the digital transmission
systems with the need for audio processing is leaving many questions
unanswered. The panel will discuss these and other issues surrounding audio
processing in a digital broadcast world.
