This thesis describes the investigation of sound timbre using perceptual and acoustical techniques, with 153 input stimuli. The acoustical methods are based on time and frequency domain representations. The thesis covers the following areas of work: 1. A consideration of previous research in timbre, the different structural forms associated with it, and different definitions concerning timbre and the timbre space representation. 2. A study concerning perceptual similarity reactions to the input stimuli, a statistical analysis of the result structure, and the implications for understanding of the structure of timbral audition. 3. Analysis and synthesis using a time-varying frequency spectrum model, with adaptive viewpoint properties to achieve appropriate time-frequency resolution. 4. Extraction of 335 timbral features from the spectral form, a statistical analysis to find those features which describe perceptual differences between stimuli, and an investigation of timbral dimensionality.
