Linear Acoustic has expanded its AERO.air transmission loudness manager to include Dolby’s implementation of the HE AAC audio coding system.

Shown last month at IBC2009, Dolby Pulse joins Dolby Digital and Dolby Digital Plus encoding as the coding systems supported by the AERO.air.

The AERO.air accepts stereo or 5.1 channel audio and delivers Dolby Digital and Dolby Digital Plus, so one box can handle current and future audio processing and encoding needs, said Linear Acoustic founder and president Tim Carroll.

The AERO.air solution is equipped with a loudness controller; upmixer; metadata manager; and full-time, two-channel downmixer for mobile services. The built-in AutoMAX processor automatically and smoothly upmixes stereo audio while passing 5.1 channel audio untouched.
