Welcome to the homepage of Dr Christian Ritz!
I am an
Associate Professor in the School of
Electrical, Computer and Telecommunications Engineering at the University of Wollongong,
|
Brief Biography
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 is
currently a Senior Lecturer. His is a member of the Visual and Audio
Signal Processing Lab of the Information and Communications Technologies (ICT)
Research Institute.
Research Activities
Current research
interests include single and multichannel speech signal processing, speech and
audio coding, spatial audio signal processing, multimedia Quality of Experience
(QoE) and signal processing for new media services.
Current projects
include spatial and multichannel speech and audio signal processing and
compression, acoustic vectors sensors for sound source localisation and
enhancement, microphone array signal processing, semantic analysis and
processing of multimedia content, perceptual processing and Quality of
Experience (QoE) estimation for media content.
I am a member of the
Visual and Audio Signal Processing Lab, part of the ICT Research Institute. I am also the
director of the University of Wollongong’s anechoic recording and
playback facility.

·
Encoding and
Communicating Navigable Soundfields, C Ritz and Ian Burnett (RMIT University), ARC
Discovery Project, 2010-2012.
·
Spatial Audio
Coding. This project is investigating new techniques for
compression of 3D audio. In particular, a new approach based on spatial squeezing has been developed.
·
Acoustic Vector Sensors for Speech Processing
and Enhancement. This project is investigating novel miniature
microphone arrays for sound recording and processing, including speech signal
analysis and enhancement.
·
Microphone
Array Recording and Analysis of Speech. This project is
investigating the recording and analysis of multiparty speech recordings.
·
Signal
Processing and Quality Of Experience For New Media
Services. This project, sponsored by the Smart Services CRC, is investigating new signal processing technologies
for new media services applications including how to measure the resulting user
Quality of Experience (QoE).
