It's through analysing
his own voice and through signal-processing techniques that composer Trevor
Wishart extends and enriches vocal materials.
Using a phase vocoder,
in an initial version produced at Ircam by Eric Viara and Yves Potard,
the composer analysed recordings of his own voice. Thereafter, with a
special program he wrote himself, he was able to reduce the considerable
mass of the phase vocoder's analytic data, and calculate sound interpolations
between various vocal materials, thereby producing unexpected results.
Here is an example, in which a voice recalling a Buddhist chant is transformed
into a cloud of insects, ending with a return to the voice.
Methods which allowed
for working on the sounds' temporal envelope enabled other transformations
too. In this example, you can hear the voice resounding like bells.
