Felipe studied acoustics in Chile where he started composing and performing music for experimental theatre developing several performance projects with actors and musicians. In 1999 he moved to Denmark to do post-graduate studies in sound perception at Aalborg University focusing on spatial sound and timbre perception. He studied composition at the Carl Nielsen Academy with the Anders Brødsgaard where he composed and premiered various compositions and took part in several interdisciplinary projects with visual artist. In 2005 he pursued his composition studies at the University of York in England with Ambrose Field and Roger Marsh focusing in electroacoustic composition and music theatre. His music has been widely played in festivals across Europe, North and South America, as well as in Australia. He has received awards and prizes in composition competitions in Austria, Bulgaria, Brazil, Czech Republic, France, Italy and Russia. Felipe is currently a lecturer at the Institute of Acoustics at Universidad Austral in Chile and his music is released by the British label Sargasso.

Although spatial audio tools are widely used nowadays in studios and concert halls, there are only few examples of robust and comfortable wearable sound systems with a suitable acoustic response. A wireless body-worn loudspeaker prototype featuring original costume elements, a hybrid full-range loudspeaker array and an improved acoustic response was designed and implemented. The size, shape and acoustic performance of the prototype was optimised using data gathered from anechoic measurements and interviews with performers and audiences. Future developments of this project will consider the implementation of an extended multi-channel performance platform to explore sonic and spatial relationships created by several wearable devices on stage synchronised with a multi-loudspeaker diffusion system.

Pairs of measured and averaged directivities have been used both for room simulation comparisons and as a basis for listening experiments with auralizations. Room simulation results show a clear influence of the changes in the representation directivity on the distribution of acoustical parameters in the room. The results of the listening experiments with auralizations show that some changes produced by directivity variations can be perceived by the listener. Among these changes, loudness was perceived in the highest degree, followed by reverberance and clarity.

A recording method with multi-channel anechoic recordings is proposed in connection with the use
of a multiple virtual source reproduction system in auralizations. Listening experiments designed to validate the
quality of the reproduction method compared with a fixed directivity representation have showed that there is a
clear improvement in the timbral quality of the reproduced sound. The improvement represented by the system
regarding the spaciousness of sound did not prove to be significant. Further applications of the method are considered
for ensembles within room auralizations as well as in the field of studio recording techniques for large
instruments. A part of this article was published previously in [1].
