Dr Wells has expertise in the development and use of digital technologies, particularly signal analysis and processing, for musical applications. Such applications range from creative sound processing (e.g. improvements to Fourier based cross-synthesis techniques) to transcription (e.g. hi-hat isolation for tempo tracking in South African jazz recordings). He is also interested in the history of signal processing in music production (e.g. manifestations and meanings of technology in productions of Joni Mitchell; the early adoption and overt use of digital technologies in Imagination’s Night Dubbing).
