High quality digital audio experiments for a signal processing first course

In this paper we provide the details of a final project in audio signal processing, used in a signal processing first course taught to second year ECE students. High quality audio signal processing covers a range of applications from the musical recording studio, musical performance, home theatre, home stereo, car stereo system, or even a personal audio player. The design/build/test aspects of the project are centered on shelving and peaking filters for channel equalization, and reverberation and flanging for audio special effects. Listening is an integral part of the experience. The project also introduces the students to graphical user interface design and interactive solution techniques. Feedback from students teams has been very positive, especially the listening tests.
