Axon has chosen to enhance its modular Synapse infrastructure and communications system with DTV audio loudness management and stereo-to-5.1 upmix algorithms designed by Linear Acoustic.

Linear Acoustic developed the Aeromax-5.1 channel loudness and dynamic range control algorithm and the upMAX upmixing algorithm with AutoMAX-II. Now, Axon will incorporate these functions into its Synapse modular system on two different platforms to protect viewers from loudness shifts.
Control of all parameters will be available through Axon’s Cortex monitoring and control software.
The new unit will accept four pairs of PCM audio to handle two-channel to 5.1-channel audio programming and a bypass input. Multiband, multistage loudness control and selectable upmixing can be applied to the input audio for consistent audio that is 5.1 channels at all times.
Another Synapse card will perform the same functions in the embedded SD, HD or 3 Gbps domain.
“These units will be a welcome expansion to Synapse’s audio for video handling,” said Axon Chief Technology Officer Peter Schut. “We have been very successful with incorporating Dolby functionality into our Synapse, and we are sure that these new products will be beneficial to our customers’ DTV applications.”
Axon will show this new module at the 2009 NAB Show.
