Learning outcomes

Course Topic The objective of this course is to provide students with fundamental knowledge about various signal processing techniques applied to digital audio signals. All of this knowledge is essential to the understanding of the function of present day digital audio processing systems and form a strong foundation of the learning of newly developed digital devices/systems with applications to audio signals. Thus this course serves as an introductory course to other more advanced digital audio processing.
