Linear Acoustic is demonstrating its range of broadcast audio control technologies at CABSAT 2010.

Highlights include the Audio Loudness Manager, AERO.qc Audio Quality Controller, PAMBDA Professional Audio and Metadata Monitor and e2 StreamStacker-HD High Density Audio Distribution System.

“The Middle East broadcast market is experiencing an increased demand for digital broadcast solutions, and along with that, effective monitoring and control of audio loudness. We want to ensure broadcasters are aware of the technologies that can help fulfill these needs,” said Christina Carroll, senior vice president of global sales for Linear Acoustic. “The, AERO.qc and PAMBDA represent a range of loudness control and monitoring solutions for mono, stereo, and surround, while the StreamStacker-HD offers advanced backhaul technology.”

The Linear Acoustic Audio Loudness Manager provides control for mono or stereo analogue transmission, and stereo and 5.1-channel surround digital transmission to prevent uncomfortable and sudden loudness shifts. When used for surround, it provides upmixing that produces compelling surround sound from stereo, and includes downmixing of surround to stereo for quality monitoring or distribution to stereo services. Options include redundant power supplies, HD/SD-SDI audio I/O, and CrowdControl dialogue protection processing.

The AERO.qc Audio Quality Controller allows users to monitor and fix loudness problems automatically in real time in production or as audio enters the plant for ingest. The AERO.qc couples the ITU-R BS.1770 loudness measurement standard with proprietary signal analysis techniques to evaluate content and make adjustments.

PAMBDA Professional Audio and Metadata Monitor is a one-rack unit monitoring tool for up to eight channels of AES or SDI mono, stereo, or surround audio, with a comprehensive display, internal speakers and a headphone output. Developed through a partnership with the TSL Professional Products Group, PAMBDA builds off the popular look and feel of the Linear Acoustic 2RU LAMBDA Professional Digital Audio and Metadata Monitor.

The e2 StreamStacker-HD High-density Audio Distribution System is capable of carrying 16 channels of audio and metadata in a single 48kHz, 20-bit AES pair to support multiple programs with surround sound and alternate languages. This e-squared system offers reference-quality audio, minimal latency and superior resilience to transmission errors. To support legacy content, it also offers an automatic soft-bypass mode to allow the system to be installed in series with other coding systems such as Dolby E.
