Welcome to the homepage of Dr Christian Ritz!
I am a
Senior Lecturer in the School of
Electrical, Computer and Telecommunications Engineering at the University of Wollongong,
|
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 Whisper Laboratories and
the Visual and Audio Signal Processing Lab of the Information and
Communications Technologies (ICT) Research Institute.
Current research
interests include single and multichannel speech signal processing, speech and audio
coding, spatial audio signal processing, and multimedia content analysis,
annotation and delivery.
Current projects
include spatial and multichannel audio compression, multichannel recording and
analysis of multiparty speech, acoustic vectors sensors for hands free
communication, signal processing of motion capture data, semantic analysis and
processing of multimedia content, semantic processing of social media content,
perceptual processing and "quality of experience" estimation for media
content and spatial and 3D audio signal processing.
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.

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 for
social media and new media services. This project,
sponsored by the Smart Services CRC, is investigating new
ways of analysing user generated content, such as Internet video and other
media content.
