In this paper, a new algorithm for a guitar modulation effect for a stereophonic reproduction is presented and tested. The algorithm is based on a signal decorrelation with its application on a vibrato effect. The decorrelation is achieved through an all-pass biquad IIR filters, while the vibrato effect consists of a periodic variation of the signal time delay. A real-time implementation of the system has been realized and several tests have been performed. An objective and subjective analysis of the algorithm is performed to verify the feasibility of the proposed approach.

A real-time implementation of the system has been realized and several tests have been performed.
