This chapter addresses the relationship between sound and visuals in audiovisual interactive projects and describes strategies for synchronizing sound and visuals in real time. It begins with a brief context of sound-image analogies, live visuals, and audiovisual performances. Subsequently, four different case studies are presented: two audiovisual live performances and two audiovisual installations. Their setups, software and hardware are described, as well as their different strategies for mapping sound to visuals. The analogies presented focus on cases where sound influences and shapes visuals. The paper aims to be a practical guide for live audiovisual artists to explore analogies and mappings between sound and visuals in audiovisual artworks and performances.
