F-2 Voice Solo to Unison Choir Transformation

Title F-2 Voice Solo to Unison Choir Transformation
Publication Type Conference Paper
Year of Publication 2005
Authors Bonada, J.
Abstract In this paper we present a transformation that pretends to convert a voice solo into a large, 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.
