Analytic Audio Systems

Analytic Audio Systems at CSIRO conducts research into the analysis of music and sound.

We create software to unravel the structure and texture of recorded audio, and we develop systems which make use of the information extracted. Examples of such systems include searching for music features and indexing soundtracks.

We have expertise in extracting features from MPEG compressed and raw audio. Much of our work is available as open source software, including the MPEG audio parsing and analysis toolkit MPEG Maaate.

Products & Projects

	Maaate Maaate is a C++ toolkit (collection of libraries) to parse and analyse audio data in the frequency domain, currently analysing compressed domain MPEG-1/2 Layers 1-3 audio files. It exposes the fields of an MPEG audio stream and provides content analysis functions. We are always seeking new applications of Maaate. Applications
	Bewdy Bewdy is a Gnome application for performing and visualising analysis with MPEG Maaate.
	CaTe CaTe is a software product that helps captioners to create standard EBU caption files from MPEG-1 videos. It automates the task of finding caption in and out times leaving the complex task of transcribing the actual scene content to the competent captioner.  We are currently seeking commercialisation of this product.
	The Continuous Media Web The CMWeb project develops a platform to generically perform annotation and hyperlinking of fragments of continuous media.

Team members

Dr. Silvia Pfeiffer, Research Scientist, Team lead

Dr. Pfeiffer's research interests include audio feature extraction and audio and video segmentation. Before cruising down under she did her PhD thesis on audio analysis for the MoCA project. She has also been involved in the standardisation of MPEG-7. Contact: Silvia.Pfeiffer@csiro.au Telephone: +61 2 9325 3141

Conrad Parker, Software Engineer

Mr. Parker's life consists of coding and music. He is a fish who loves to swim in the ocean of open source software. He has shared with us lots of audio software and other works of art. Contact: Conrad.Parker@csiro.au Telephone: +61 2 9325 3133
