ERATO (2003 – 2006) Anechoic recordings from Università di Ferrara. The main objectives of this project were identification, virtual restoration and revival of the acoustical heritage in a few, selected examples of the Roman theatre and the roofed odeum in a 3D virtual environment. The virtual restitution integrates the visual and acoustical simulations, based on the most recent results of research in archaeology, theatre history, clothing, theatre performance and early music.
