By timbre gesture we mean a sonic (as opposed to body) gesture that mainly conveys artistic meaning through timbre rather than other sonic properties. The system is designed and developed to be used in free improvisation and composition. Our prototype is powered by a neural network trained using a supervised learning approach on a set of sonic gestures representing the stimulus (or input) and a correspondent set of sonic gestures representing the reactions (or output). This model is then used to explore and generate new musical material. Here, we present an informal evaluation of our system, based on two use cases. In the first, the system is trained using MFCC analysis, while the second uses Constant-Q Transform spectrum. Participants were asked to rate our system's generated audio, particularly in respect of timbre. Results showed that although tiNNbre has been tested offline...

Together with pitch, timbre, intensity and duration, the position of sounds in space determines its role as a whole. Even more, the movement of sound in space allows them to evoke, with the help of the interpreter, representations of physical environments and gestures. The gesture as a source of motion and the movement that follows, allows you to dive fully in the sound environments depicted. The relevance of this aspect has led us to study and to experiment the behavior of a virtual environment, more precisely a virtual Acousmonium, testing on it various gestures that are part of the tradition repertoire of acousmatic interpretation. The goal is to verify its effectiveness as a compositional tool, as a tool for studying, for the preparation of acousmatic music performances, and as a didactic support for interpretative practice.

Si presenta come una postazione di ascolto, costituita da una sedia e da un tavolo su cui si trova un tablet, posizionata al centro di uno spazio di diffusione sonora quadrifonica. Il gioco é organizzato in livelli, di difficoltá crescente, in cui l'obiettivo é quello di riconoscere una frase musicale che rappresenta una notizia vera. All'inizio di ogni livello viene fatta ascoltare la frase musicale "vera" che, successivamente, viene moltiplicata e le cui copie vengono sottoposte a un processo di distorsione. Passato un lasso di tempo direttamente proporzionale alla difficoltá del livello, viene sbloccata la possibilitá di selezionare, attraverso la visualizzazione delle posizioni delle sorgenti sul tablet, quale tra le voci ascoltate é quella rimasta inalterata.
