Analysis and Perception of Sound (Level 11) (P01257)

? Credit Points : 10 ? SCQF Level : 11 ? Acronym : PHY-P-AnPerSou

An introduction to the analysis and perception of sound. The mathematical underpinnings of Fourier theory and digital signal processing are described, especially with regard to music and audio applications. The emphasis is on algebraic work, and on practical computation for sound analysis. A review of the human perception of sound includes an introduction to current theories of the behaviour of the human ear.

Summary of Intended Learning Outcomes

Upon successful completion of this course it is intended that a student will have:
(1) A thorough and detailed technical and mathematical understanding of Fourier Theory with regard to audio signal processing.
(2) The ability to program audio processing code in the Matlab language.
(3) The ability to design and program specialised signal processing operations, such as the phase vocoder, and various audio effects including flangers, chorusers and artificial reverberation.
(4) An understanding of the Fast Fourier Transform and its significance.
(5) An increased facility with various mathematical concepts, including complex number representations, trigonometry, inner product descriptions, orthogonality as well as some linear algebra.
(6) An appreciation and understanding of issues which separate real-time from non-real-time audio signal processing applications.
(7) An understanding of, and the ability to program simple digital filter structures, including low-, high-, all- and band-pass filters.
8) An understanding of the structure and functioning of the human hearing system, and familiarity with current theories of the perception of pitch and timbre of musical sounds.
