This thesis explores the audio field in current computerized systems, so as to contribute to the use of intrinsic characteristics of audio and its expressiveness in communicational digital environments. The issue under study is related to systematized articulation of audio, which allows the use of techniques that enable the randomness of sounds, thus broadening the conceptual range of expressiveness of cognitive and communicational processes in hypermedia environments and metaverses. The philosophical foundations of this work are on the area of Linguistics (Ferdinand de Saussure) and Semiotics (Charles Pierce), which justify the understanding of the role of audio in current communication processes. The studies of George Landow and Theodore Nelson on Hypertexts had the role of bringing into light the computerized systematization ability of communication processes, what has motivated us to explore audio, its peculiarities and computational specificities in digital environments. In this context, the random component is introduced in the systematization so that the elements of human perception detailed by Charles Pierce can be used individually. Afterwards we will discuss, some possibilities of application of random audio understood as sonic textures in communication processes and music. As main result, this work proposes that random audio can be employed in research projects of virtual environments (metaverses), culminating in a formulation of soundscapes (Murray Shafer) starting from the concept of hyperaudio
