Vocal recomposer is an interactive sound installation, based on the history of the vocoder. A technology, best known for its use in science fiction and popular music, it was mainly developed in military research during WWII, as part of the secret then Project X / Sigsaly. Through a custom interface, I acoustically magnified the very point where the original voice is deconstructed beyond intelligibility and just before the moment of stitching together takes place. The proposed virtual version for the Metaverse allows people to move around the different stages of the deconstructing and reconstructing of voices.
