Based on Wishart’s literature, this paper investigates the most frequent and significant recorded voice transformation processes, and its correlation with the composer’s compositional goals, presented on four Trevor Wishart’s acousmatic pieces: Vox-5, Tongues of Fire, Globalalia and Encounters in the Republic of Heaven. Although Wishart developed new sound transformations using the phase-vocoder, the selection of the materials takes a key role in determining which sound metamorphosis would fit his aesthetic goal: retain the source credibility from the listener perspective. This articles shows how his compositional goals in each piece demands both specific recorded materials and precise transformation processes in order to achieve his intention with respect to the listener. Hence, one of the main relevant aspects of Wishart’s work for electroacoustic composers is to reveal – from the audience point of hearing – subtleties between natural and artificial transformations of voice samples.
