MAT 240F: Digital Audio Programming: Audio Analysis and Music
Information Retrieval
UCSB, Spring Quarter, 2008

Course Description
The
focus of the MAT 240F course is on
audio analysis and signal processing techniques applied to sound/music
databases and music information retrieval systems. We will work with
various C++ libraries for signal analysis and feature extraction to
develop skills in time-domain processes such as beat following, tempo
analysis, and song segmentation, and in spectral-domain analysis
techniques such as pitch estimation, spectral peak analysis and
tracking, and instrument signature identification. The topic of feature
vector design will play an important role in the development tasks.
Applications will include music segmentation, finger-printing,
thumb-nailing, clustering and genre classification, and user preference
matching.
Prerequisites
Students are expected to know the
basics of digital audio signal representation and processing, and to be
proficient in C, C++, or Java (Smalltalk and/or SuperCollider also
useful). Grading will be on the basis of in-class participation and
programming projects.
Course Materials
Readings will be distributed in class
and via the course web site. See the downloads section below.
