This paper describes initial research conducted in The Ra-dio Sound Studio Project. 1 The aim of the project is todevelop novel sound design tools by digitally model histor-ical sound effects, found in the radio drama studio, utilis-ing methods from sound computing, ethnography, and de-sign. These novel sound tools will address both artisticsound practices as well as more utilitarian sonic interac-tion designs for new objects. The project also provides atangible approach to connecting new sound design devel-opments with historical literature and practice, and createnew opportunities for radio, TV and Foley studios. Thispaper focuses on the process of selection of the soundingobjects to be modelled, which was based on an in-depthinterview with Sveriges Radio’s sound engineer and soundmaker Michael Johansson as well as observations of hisFoley practice. It also describes the initial modelling ofone of these objects, and plans for future work
