- In this paper, we describe the implementation of the multi-channel AAC encoder system for digital audio broadcasting. The encoder system is based on MPEG-2/4 Advanced Audio Coding (AAC) and capable of real-time encoding up to 5.1 channel audio. To give a flexible functionality, it consists of multiple DSPs, IF.C6I937 and TCP/IP interface and 6 channel audio input facilities. The reference AAC decoder was implemented for verification test of the encoder, The encoder system also integrated with AAC streaming system for interoperation test. Through these tests, the encoder system was verified to be a good solution for high quality audio broadcasting.
