MUMBAI, INDIA – Linear Acoustic, the leading authority in loudness control and upmixing solutions for digital television, is featuring its AERO.airTM 10-Channel Transmission Loudness Manager and L.A.M.B.D.A. Professional Digital Audio and Metadata Monitor at the 2009 Broadcast India Convention, October 29-31, 2009 in Mumbai, India (Booth H-810).

“With HDTV just starting to take hold in India, Linear Acoustic would like to make sure that broadcasters are prepared to handle the loudness issues typically associated with the switch to HDTV from day one,” says Christina Carroll, vice president of sales and marketing for Linear Acoustic. “By addressing loudness control early on, broadcasters in India can ensure that they will have a smooth transition to HDTV.”

The AERO.air (5.1) 10-Channel Transmission Loudness Manager is the world’s first TV audio processor to feature built-in Dolby® Pulse (Dolby’s implementation of HE AAC), and Dolby Digital (AC-3) encoding. The AERO.air (5.1) unit is a third-generation solution designed to deliver 5.1 channel surround sound from a stereo source while maintaining balanced signal levels between all broadcast programming. Saving time, money and space, this key addition allows broadcasters to install one simple, easy-to-use unit to handle complete audio processing and encoding for local, network and EAS broadcasting. Incorporating an HD/SD-SDI input, this solution also provides air-proven dynamics processing to allow seamless integration of local two-channel audio and network 5.1 audio.

Designed to enable audio and metadata monitoring throughout the entire broadcast chain, the Linear Acoustic LAMBDA Professional Digital Audio and Metadata Monitor displays and reproduces up to 16 audio channels from AES or embedded HD/SD-SDI input. The system accepts audio metadata via 9-pin serial input or extracts it from the VANC space of an applied HD-SDI input. Audio and metadata are displayed in combination to allow for accurate monitoring. Included loudness monitoring per ITU BS.1770 enables operators to verify program loudness quickly and accurately.
