Abstract :
In this paper, a multichannel sound scene visualization tool is designed and implemented based on MPEG surround multichannel decoder. The aim of this tool is to effectively display frequency dependent dynamic characteristics of multichannel sound scene. It uses only spatial cue parameters extracted from MPEG Surround bitstream without additional computations such as T/F transform.
