A graphical user interface to facilitate the creation of an audio effect using icons, a given configuration of icons and interconnections being modeled and employed to generate a given audio effect.

A method and process to set the parameters of a Control Algorithm and to synthesize and generate a variety of sounds and vibration that are normally not available on a specific acoustic stringed instrument are disclosed. The technical problems of generating a different timbre, sound and vibration of a stringed acoustic instrument (Controlled Instrument) in real time are solved. The invention describes a process (Cloning Procedure) where specific set of parameters needed to imitate a target instrument are defined; The imitation of the Target Instrument's timbre on the Controlled Instrument is performed by the Control Algorithm which employs two digital Linear-Time-Invariant systems to drive the actuators based on by controlling the actuators with a couple of digital Linear-Time-Invariant systems that receive the vibration signal from the measurement apparatus. The process can be optionally deactivated, thus having the Controlled Instrument acting as a traditional acoustic instrument.

A mixing signal processing technique modifies digital audio recordings to simulate the linear and nonlinear effects of propagation and mixing of sounds in air. When multiple sounds or complex sounds comprised of multiple frequencies in the audible spectrum propagate in such a nonlinear medium, they transfer energy into sound at new frequencies given by the sums and differences of the original signal frequencies. The mixing signal processing technique may improve the ability of a system to reproduce the effects of a live performance using a digital audio recording.
