Linear Acoustic will unveil its latest in audio processing solutions including its AERO range, that provide key functionality for efficient and accurate processing of audio signals and metadata in today’s broadcast market.

The AERO.qc allows users to fix loudness problems automatically and in real time as audio enters the plant and is fed into the ingest server. This ingest quality-control system provides the tools necessary to get audio loudness right. The AERO.qc uses the ITU BS.1770 loudness-measurement specification, coupled with proprietary signal evaluation techniques, to evaluate each piece of content and make adjustments. Operator intervention can range from full control of measurement and audio adjustment to highly automated processing that requires little oversight. Front-panel metering offers instant go/no-go feedback and precise loudness adjustment.

The AERO.pro production audio maximizer enables users to achieve commanding sound quality in news and other locally produced content. The processor takes control of audio quality, providing specialized processing that makes it easy to combine studio content with prerecorded spots, insertions, and live remotes without fear of overload or audible side effects. By helping to ensure that sound quality is maintained all the way to the viewer, the AERO.pro gives local content the same sound that previously characterized only network-produced audio. The AERO.pro features multiband stereo processing, along with analog and digital inputs and outputs.

The next-generation AERO.air 10-channel TV audio processor (previously called the AEROMAX-5.1:XL) features built-in Dolby Digital (AC-3) encoding. The AERO.air system enables broadcasters to deliver compelling 5.1-channel surround sound while saving time, money, and space. It is equipped with a loudness controller, upmixer, and metadata manager, as well as full-time, two-channel downmixing to support legacy analog paths. Built-in AutoMAX processing fixes two-channel audio that is broadcast wrongly signaled as 5.1 channels.

The AERO.one DTV Audio/Loudness manager offers broadcasters a simple and cost-effective solution for guarding against loudness shifts and loss of surround sound. Built-in loudness control, metadata control, and optional transmission encoding make AERO.one a solution for affiliate stations seeking to match local and network content and thus deliver a seamless surround-sound experience for their viewers. Upmixing is provided by the UPMAX algorithm, which provides 5.1-channel audio with complete downmix compatibility. The AERO.one also includes the new AutoMAX-II auto-detection algorithm, which smoothly and automatically bypasses upmixing when applied content is already 5.1 channels. Optional Dolby Digital (AC-3) encoding and HD-SDI input and outputs are available.
