报告题目:Spatial Audio Signal Processing Research @ the University of Wollongong (澳大利亚卧龙岗大学空间音频信号处理研究进展)

 

 

内容概况:

In this talk, an introduction to the University of Wollongong and Christians School, Faculty and Research lab will first be given. This will be followed by an overview of the spatial audio signal processing research. It will include focus on research into recording, compression, enhancement and reproduction of spatial audio for application in areas such as spatial audio teleconferencing and multimedia entertainment. A brief introduction to spatial audio recording techniques using co-incident microphone arrays will be first presented. This will be followed by a description of the Spatially Squeezed Surround Sound Coding (S3AC) pioneered in Wollongong and applied to compressing multichannel audio formats including 16 channel 3D audio. Approaches to perceptual enhancement of these compression techniques based on psychoacoustic models will be described. The final part of the talk will describe multichannel reproduction of spatial audio as researched in Christians group.

 

 

个人概况:

Christian graduated from the University of Wollongong in 1999 with a Bachelor of Electrical Engineering and a Bachelor of Mathematics and a PhD in Electrical Engineering at the University of Wollongong in 2003. His PhD research focused on very low bit rate coding of wideband speech using Waveform Interpolation (WI). Since 2003, Christian has held a position within the School of Electrical, Computer and Telecommunications Engineering at the University of Wollongong and was promoted to an Associate Professor in 2013.  He is a member of the Visual and Audio Signal Processing Lab of the Information and Communications Technologies (ICT) Research Institute and leads the speech and audio signal processing research activities of the institute and School. His current research interests include single and multichannel speech and audio signal processing, spatial audio signal processing, acoustic signal processing for microphone and loudspeaker arrays, acoustic design of musical instrument and multimedia Quality of Experience (QoE).
