This essay concerns the historical developments and the conceptual predecessors of a particular development in artistic creation and design, one that involves the creation of audiovisual experiences and the exploration of the fusion between the two modalities and the corresponding media. It proposes an identification of a convergence between aural and visual modalities and audio and visual media.
By outlining the concurrence between visual arts and music to the digital unification of audiovisual media, significant developments are revealed concerning the exploration of a perceptive equivalency, established by analogy or conversion between sound and image, as precursors of an audiovisual aesthetics involved with intermedia explorations.
