This thesis documents a body of research that links the field of electro-acoustic diffusion and spatialisation with practice in the music and film post-production industries. Three research questions are posed: "How can the physical user-interfaces used for panning by the music and film post-production industries offer creative alternatives to the fader-based hardware approach commonly used for electro-acoustic performance?" "How can a Digital Audio Workstation (DAW) be used as an alternative to dedicated panning hardware? "How can emerging programming technologies offer creative alternatives to the MAX/MSP or hardware-based tools commonly used for sound spatialisation?" This practice-based PhD addresses these questions by designing, developing and testing a set of hardware and software tools, the Requirement Specification for this `Toolset' results from literature review and critical analysis of current systems to determine potential research gaps. This analysis is followed by the selection of a suitable methodology for development and testing that allows the research questions to be explored effectively and results in the following Toolset: OctoPanner: Amulti-featured eight-channel 3D touchscreen panner application for Apple's Mac OS X controlling a DAW hosted customisable VST 3D panning plug-in with C++ source code. ShapePanner: A synchronisable shape-based sequencer application for Mac OS X inspired by Experimentalstudio's Halaphon. The user is ab{e to describe the movement of sounds in a 3D space using shape primitives such as lines and circles and thus extend the capabilities of the Toolset beyond realtime manual manipulation of sounds. 3DMIDIVisualiser: An application to allow the user to work without access to a multi-speaker system by enabling the movement of sounds to be viewed within a virtual room. Foot Puck: Afoot-controlled panning controller enabling a musician to spatialise their instrument using foot movement. Initial prototyping was achieved using Cycling `74's Max/MSP but the final applications are written using Apple's Cocoa environment and Objective C. This thesis gives close analysis and discussion of the various stages of research carried out; including the use of Apple's CoreMlDl and CoreAudio Clock OS X Core Services in a Cocoa application.
