Abstract :
This paper presents a complexity analysis of a spatial audio coding scheme (known as MPEG surrounding) based on a commercially available programmable device. The analysis mainly focuses on the complexity of spatial audio cue analysis and synthesis, especially for the additional special tools used during the spatial cue synthesis stage. The analysis results can be a reference during building up a SAC codec on a DSP
