Recording sound sources for spatially adaptive, immersive environments can present a problem in cases where the listener is able to move into close enough proximity to the sound source that the source is no longer a point source. This paper presents a recording and encoding methodology for representing these complex sound sources in six degree of freedom immersive environments in a way that allows them to retain their perceptual size based on the listener's distance. This paper also suggests a method for using statistical directivity data to retain a sound source's frequency-domain signature based on its directivity characteristics and its rotation relative to the listener. It also suggests a method for calculating the damping of a sound based on a listener's distance that accounts for the perceptual size of the source as it approaches or leaves appearing as a point source. The damping and directivity methods suggested can be applied to simple sound sources as well; allowing the methodology to be applied to all the virtualized sound objects in a scene using the same approach.

<jats:p>Marlos Nobre is a Brazilian composer, pianist, and conductor. His music presents a unique characteristic that combines Brazilian features with advanced compositional techniques. His pluralistic musical view went through several phases, from tonal to modal, polytonal, atonal, serial, and aleatoric until he defined his own style, which became a combination of everything he had learned and filtered.</jats:p>
