As the demand for digital SD and HD services continues to grow in India, so too will the need for broadcasters to manage their audio loudness.”

The Linear Acoustic TV Audio Loudness Manager provides transmission control for mono or stereo analog, stereo AES, and 5.1 surround digital to prevent uncomfortable loudness shifts. When used for surround, it provides compelling surround sound from stereo sources, and includes downmixing of surround to stereo for quality monitoring or distribution to stereo services. Options include dual 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. Operator intervention can range from full control of measurement and audio adjustment to highly automated processing that requires little oversight. Full-color front-panel metering provides comprehensive real-time loudness indication. Options include Dolby® E/AC-3 decoding, additional advanced production upmixing algorithms, AERO-style multiband loudness and dynamic range control, multichannel analog output with speaker EQ, and HD/SD-SDI input and output. A hardware remote volume and speaker control is available separately.

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 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.
