Adtec’s audio embedding carrier is an add-on hardware option enabling additional audio codecs and audio encode channels per video. In addition to encoding MPEG 1 layer 2 and MPEG 2 layer 2 audio, the carrier adds support for Dolby digital AC3, ACC-LC and HE-AAC (v1/v2) mixed mode audio encoding. Allocation of audio channels depends on the configuration of your solution.
