Linear Acoustic to Unveil DTV Audio Processor at NAB 08
Linear Acoustic, a manufacturer of customer-centric
multichannel sound solutions for digital broadcast, will be showing the new
AEROMAX:one digital television audio processing system, which supports built-in
Dolby(R) Digital (AC-3) encoding at NAB 2008.
Inconsistent DTV audio loudness, or the so-called “loud
commercial problem” is the number one complaint of television viewers and
it is driving them away. Stations simply do not have the time to manage the
huge variety of stereo and surround sound programming that viewers expect,
while ensuring compliance with Federal regulations.
“It is clear that with the transition to digital
completing early next year, broadcasters need simple, cost effective audio
solutions right now,” said Linear Acoustic Founder Tim Carroll. “The
AEROMAX:one is the feature-packed, entry-level answer.”
The single-rack-unit AEROMAX:one accepts four AES pairs of
audio to handle two-channel to 5.1 channel network or local audio and a
separate pair of channels for SAP or visual descriptive programming. The unit
can apply multiband, multistage loudness control and upmixing to the local
audio, allowing it to be matched to 5.1 channel network audio, while leaving
the network audio untouched. The AEROMAX:one is especially appropriate for
affiliates needing a simple, cost-effective solution for local loudness control
and Dolby Digital (AC-3) encoding.
AES I/O plus metadata and GPI control are standard, and a
software remote will be available for the AEROMAX:one later this year.
Available options include built-in Dolby Digital (AC-3) encoding, metadata
output, and HD-SDI embedding and de-embedding.
