This module introduces the fundamental technologies employed in sound and music computing which are grouped into three major areas: Sound, Music, and Interaction. It begins with an introduction to sound production, propagation and perception, followed by digital sound recording, editing, post-processing and compression. Its core components consist of the analytic and synthetic approaches of sound and music. The analytic approach pertains to analysis and understanding, whereas the synthetic approach pertains to generation and processing. Interaction aspects include multimodal mobile music interface and sound interaction design. Finally, music information retrieval will be introduced as an application of analytic techniques.

This module aims at providing students with an in-depth understanding of modern audio technologies, ranging from low-level audio representation to high-level content analysis; and from basic waveform to advanced audio compression and compressed domain processing. Upon completion of this module, students should be able to perform research such as narrowing the semantic gap between low-level features and high-level concepts. Topics include: discretisation, sampling, audio formats, audio synthesis, spatial audio, feature extraction, speech recognition, audio segmentation and summarisation, source separation, and audio compression.
