Linear Acoustic ships TV audio processor with Dolby Digital encoding
January 13, 2008
Linear Acoustic is now shipping its next-generation AEROMAX-5.1, a 10-channel TV audio processor that features a loudness controller, upmixer and metadata manager. The processor accepts 5.1 network audio, two-channel local audio and digital or analog auxiliary/EAS stereo audio. Optional HD-SDI audio and metadata input and internal Dolby Digital (AC-3) or Coding Technologies aacPlus (MPEG-4 HE AAC) encoding are also available.
"We've designed the AEROMAX-5.1 to help broadcasters transition to digital as smoothly as possible," said Tim Carroll, president and founder of Linear Acoustic. "The processing capabilities of the AEROMAX-5.1 make it easier to deliver the consistent and compelling surround sound for television that viewers expect."
The AEROMAX-5.1 combines network-proven dynamic processing algorithms with upMax surround-sound upmixing and extensive local features such as a full-time, two-channel downmix to feed legacy analog paths. The system's built-in AutoMax processing fixes two-channel audio that is broadcast wrongly signaled as 5.1 channels. This eliminates the image shift that occurs as dialogue moves from the left and right front speakers to the center speaker when programs transition between two and 5.1 channels.
AEROMAX-5.1 takes advantage of metadata for the proper processing of audio and to control upmixing and other features offered by the unit. Network and local audio can be handled separately, with metadata used alone or in combination with dynamic range processing, to ensure a high-quality sound experience true to the original audio source.
