“Throughout the years, the Australian broadcast industry has really responded to viewer concerns regarding program and commercial loudness,” says Christina Carroll, vice president of sales and marketing for Linear Acoustic. “However, the upcoming nationwide switch to digital will bring a whole new set of DTV audio challenges as broadcasters work to improve the listener experience. Our Linear Acoustic loudness control products have been used worldwide to mitigate these very concerns, and we’re pleased to showcase our products to the Australian market during this key time of preparation prior to the DTV roll out in 2010.”
The AERO.air (5.1) 10-Channel Transmission Loudness Manager is the world’s first TV audio processor to feature built-in Dolby® Digital (AC-3) encoding. In addition, 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.
The Linear Acoustic LAMBDA Professional Digital Audio and Metadata Monitor is the first audio monitor that can accept and decode Dolby Digital Plus and Dolby Digital (AC-3), directly from an applied DVB-ASI transport stream. A complete package for highly accurate digital audio and metadata monitoring throughout the entire broadcast chain, LAMBDA displays and reproduces up to 16 audio channels from AES or embedded HD/SD-SDI input. The system also accepts audio metadata via a 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.
