Audio Processing Course

This course was given at the University of Amsterdam during the 3rd trimester of 2002/2003. The course was meant for 3rd year "Computer Science/Artificall Intellignece" students.

Most of the course details are now pretty much outdated. However the lecture notes, the literature survey, and the practical assigmments might still be useful, so I keep these pages available online.

Lectures are given by Frans Groen, and Jan van Dijk [jan.van.dijk * hum.uva.nl] on Mondays, 11.15 - 13.00,
Roetersstraat 15, room A.303

Practicum is organized by Wojtek Zajdel on Tuesdays, 9.30 - 12.30,
Plantage Muidergracht 24 (Euclides), room p.124
