Linear Acoustic Helps Audio Obey the Law
“I’m concerned about bridging the dichotomy
between quality and obeying the
law,” said Tim Carroll, founder and president
of Linear Acoustic, as he unveiled two
of his company’s latest accomplishments.
“We’re convinced that there’s a better
way. We can protect a broadcaster from a
fine, but we’re not going to do it to the detriment
of the content producers.”
Carroll, speaking at a Monday press conference,
said that with the new broadcast
audio loudness regulations, there’s a delicate
balance to strike between delivering a quality
experience to television consumers and
staying within broadcast regulations.
Two new Linear products have been engineered
to help broadcasters do just that:
AERO.calm and the LQ-1000 Loudness
The AERO.calm — or “Coded Audio
Loudness Manager” — provides management
of audio content within the compressed
domain, preserving quality that could otherwise
be lost in additional decoding and reencoding
steps. The unit supports AES, SDI,
DVB-ASI, and IP transport stream I/O.
The LQ-1000 provides “high density”
loudness metering and features real-time
Dolby Dialogue Intelligence technology.
Like AERO.calm, it works with a number
of signal formats, including AES, SD/HDSDI,
DVB-ASI (MPEG transport streams),
as well as with IP transport streams.
