Audio Processing and Indexing


Admission requirements

C, C++.


During this seminar the fundamentals of audio processing and indexing will be studied. Applications in the area of speech recognition, audio synthesis and content based audio retrieval will be discussed. State of the art work on content based audio retrieval will be studied and presented by the participants.

The seminar starts with several lectures and accompanying assignments in the form of workshops; followed by a literature selection, study, and presentations by all the students; the seminar ends with final project demos / presentations.
