Linear Acoustic to Showcase Loudness Solutions at IBC

Linear Acoustic will unveil its latest in audio processing solutions at IBC2008 including its AERO range of products that provide key functionality for efficient and accurate processing of audio signals and metadata.

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. 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.

The 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. The next-generation AERO.air 10-channel TV audio processor (previously called the AEROMAX-5.1:XL) will also be shown. It 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.

The DTV Audio/Loudness guards against loudness shifts and loss of surround sound. It has built-in loudness control, metadata control and optional transmission encoding. Upmixing is provided by the UPMAX algorithm, which provides 5.1-channel audio with complete downmix compatibility. The 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.

Linear Acoustic will be at Stand 8.C11.
