In this paper we present a transformation which pretends to convert a voice solo into a big unison choir. The basic idea behind the presented algorithm is to morph the input voice solo (dry recording) with a recorded sustained vowel of a unison choir. The processing algorithm is based on the rigid phase-locked vocoder adapted to harmonic sounds. Pitch and timbre are taken from the voice solo, and the local spectrum comes out from the analysis of the unison choir sample.
