Recently introduced, the ISO/MPEG-2 Advanced Audio Coding (AAC) coding technology provides a powerful framework which covers almost any application from simple monophonic compression to full-featured multi-channel coding. This paper discusses approaches and results of an implementation effort of a 5.1 AAC multi-channel encoder on a high performance floating point catalog DSP platform. Based on a new AAC coding strategy, this leads to a very efficient encoder on a single DSP, thus enabling cost-effective high-quality multi-channel encoding also for consumer type applications.
