Linear Acoustic AMS Authoring and Monitoring System is a comprehensive solution for real-time authoring, rendering, and monitoring of advanced audio programs for the ATSC 3.0 Digital Television System.
The audio system in ATSC 3.0 provides listeners with a personalized, immersive audio experience using Next Generation Audio (NGA) technologies, including MPEG-H. AMS simultaneously delivers advanced audio for ATSC 3.0 broadcasts and 5.1-/2-ch audio for ATSC 1.0 broadcasts.
On the production side, AMS allows the authoring engineer to easily control and monitor the interactive features of MPEG-H offered to the viewer and build presets for different listening environments and devices from mobile phones and tablets to immersive home theaters.
AMS is equally at home in other parts of the broadcast chain where it can be used to monitor and validate audio streams authored upstream.
In either application, AMS can simultaneously output 15 channels of discrete audio with a metadata control track, a 5.1-channel rendered output, a 2-channel rendered output, and a dedicated monitoring output.
AMS is also equipped with Linear Acoustic APTO, the state-of-the-art loudness adaptation technology designed to carefully control audio levels in a way that preserves the transients, sonic image, and artistic intent of the source while ensuring loudness consistency and compliance for any desired target.
