Abstract
An apparatus for transforming an input sound signal includes a synthesiser which manipulates, in accordance with a manipulation parameter, a pitch deviation envelope to derive a manipulated pitch deviation envelope. A filter transforms the input sound signal from a resampling of the input sound signal with respect to the manipulated pitch deviation envelope. The manipulation parameter may be a user-defined peak pitch deviation of an output sound signal. Another apparatus for transforming an input sound signal includes a synthesiser which manipulates, in accordance with a manipulation parameter, a pitch deviation envelope selected with reference to the manipulation parameter to derive a manipulated pitch deviation envelope.
