Linear Acoustic at Broadcast Asia, 2011

For Linear Acoustic, BroadcastAsia2011 will be a showcase of innovative new products, new features, enhanced designs, and exclusive upgrades. Most obvious will be the new 2RU version of the company’s signature TV audio processor: the AERO.air™. Only size and weight were lost in the reduction from the 3RU unit. Key features that once were optional upgrades will be made standard on many 2011 versions of the Linear Acoustic product line. During the show Linear Acoustic also will introduce a new member of the AERO family.

AERO.lite™ Transmission Audio/Loudness Manager

AERO.lite™ is the new slimmed-down, stereo-only version of the popular AERO.one™. Designed specifically to give local and regional broadcasters the advantage of Linear Acoustic loudness control technology, AERO.lite provides legal compliance and the features necessary for smooth audio transmission. AERO.lite is the lowest priced processor in the Linear Acoustic AERO series of transmission audio loudness managers.

AERO.air™ Transmission Audio/Loudness Manager

The AERO.air™ continues to solve the newly regulated “commercial loudness problem” and now offers more features in a sleek, smaller, and lighter 2RU chassis. Many optional upgrades on last year’s model are now standard features. HD/SD- SDI I/O allows for de-embedding and re-embedding of up to 16 channels of audio plus SMPTE 2020 (VANC) metadata. UPMAX-II™ provides a more spacious and stable 5.1 upmix from a stereo source. CrowdControl™ ensures dialogue is preserved even in rich stereo mixes. The new AERO.air retains all the features that have made it the proven choice for DTV audio transmission and loudness management. 

AERO.file™ File-Based Audio/Loudness Manager

AERO.file™ brings proven audio technologies to the file-based domain, where they can be even more effective. Advanced RadiantGrid transmuxing and transwrapping enables the audio essence to be extracted from a host of popular file wrappers, measured, scaled, and processed, then re-wrapped in sync without disturbing other video or data essences. Standard support for WAV, AIFF, Dolby^® Digital (AC-3), Dolby Digital Plus, MPEG 1 Layer II, MP3, AAC, ACELP, WMA, and AMR is included. And new this year, AERO.file adds Dolby E encoding and decoding and EBU mode to complement the existing ITU-R BS.1770 loudness measurement.
