Research Project: Lossless-to-Scalable Multi-Channel Audio Coding

The need of designing a scalable multichannel audio codec mainly derives from the industrial requirements. Audiences always seek a sense of presence when exposed to audio sound while multichannel audio actually gives more compelling experience than conventional mono or stereo one. When take transmission condition into account, a digital audio compression system, which can provide quality- scalable multichannel audio bitstream, is most desirable for streaming over heterogeneous networks. MPEG Advanced Audio Coding and Dolby AC-3 are the most prevalent industry standards using perceptual audio coding techniques, which provide mature coding schemes for audio with different channel configurations. However, the role of psychoacoustics for multichannel audio has not yet been unveiled thus leaving room for improvement of codec; and not much work has been done on scalability for multichannel audio sources. The aim of the research proposed here is to develop a multichannel audio coding system with fine grain scalability. New solution is expected to present based on a better understanding of binaural perception and inherent attributes of multichannel audio sources.
