This thesis encloses five publications which describe technologies for recording, analysing, manipulating, and reproducing spatial sound scenes, which confront many of the challenges associated with the development of systems capable of delivering high quality audio within virtual reality and augmented hearing contexts. The technologies detailed herein operate based upon microphone array signals, which have been transformed into the time-frequency domain. Through the adoption of an assumed sound-field model, an input sound scene may be parameterised and decomposed, which permits the optional manipulation and subsequent reproduction of the sound scene over an arbitrary playback setup. This type of processing often leads to a high degree of playback flexibility and perceived spatial accuracy, which would otherwise be unattainable when using signal-independent and non-parametric alternatives.
