Scalable real time audio processing

The AERO.soft enterprise-class television audio processor is being displayed at IBC2015. AERO.soft features Linear Acoustic processing engines identical to those in the AERO.100/1000/2000, with optional Dolby coding and while supporting the ongoing transition to AoIP.

Chris Shaw, vice president of global sales, television, for Linear Acoustic, said, “Trusted Linear Acoustic AEROMAX loudness control, UPMAX upmixing, and ITU-R BS.1770 metering and logging, plus available Dolby encoding and decoding, are available as an enterprise solution. AERO.soft enables both audio signal processing and I/O to be tailored to a facility’s changing needs, expanding only as needed. The Linear Acoustic SDI xNode or any of the Axia AES or analogue xNodes enable integration into a ‘traditional’ non-AoIP environment, while also fitting seamlessly into any existing AoIP system.”

AERO.soft, with its fully customisable I/O, loudness control and logging make configuration and maintenance easy, claimed the company. The AERO.soft Engine can host eight AEROMAX 5.1 (5.1+2+2) or AEROMAX 2.0 (2+2+2) processing instances. This approach to audio processing allows simple and future-resistant upgrades to support additional program channels, or new features and technology like personalised and immersive audio.

Adoption of AoIP is accelerating in television broadcast plants around the world, building on the proven success from the radio broadcast industry where it has been commonplace for well over a decade, supporting thousands of on-air facilities every day, said Linear Acoustic.

AERO.soft uses the established Livewire+ AoIP format to interconnect with nodes used to convert AoIP to and from SDI, AES, and even analogue signals. Livewire+ is the next generation of Livewire, developed by Telos in 2003 and which forms the basis of the open AES67 AoIP standard.
