The audio collection and the video archive of the Slovenian Theatre Institute – the Theatre Museum collect, professionally process, and store theatre-related materials on various audio- and video-storage formats. They also work on digitalizing any analogue recordings. The materials are incredibly important items of cultural heritage and a valuable testimony of the most ephemeral art form. It is sometimes used in exhibitions and other Institute projects and is available to users for research or study purposes.
The main segment of the collection and the archive are recordings of theatre performances, radio plays, original soundtracks and sound effects of performances, as well as interviews with theatre creators.
