SOME CONSIDERATIONS FOR SPATIAL DESIGN AND CONCERT PROJECTION WITH SURROUND 5 . 1

This article describes the process of composing an electroacoustic music piece using a 5.1 surround sound system for studio monitoring and diffusion in a concert hall. Specific spatial ideas explored in the composition of the piece are explained in connection to the possibilities offered by this system, as well as to its limitations. Considerations are outlined regarding the quality of the spatial performance of the system in a concert hall as compared to its performance in a studio in the compositional process. Some conclusions are drawn as regards limitations and advantages of surround 5.1 systems for electroacoustic music composition and some suggestions are made for a more effective concert performance.
