Technological innovation has opened new perspectives for the preservation and valorization of intangible cultural heritage. This study explores the use of virtual reality (VR) for the dissemination of opera, focusing on the Rossini Opera Festival (ROF). By employing immersive technologies, the project overcame traditional geographical and physical barriers, making the festival accessible to a wider audience within the framework of the “Casa delle Tecnologie Emergenti” (CTE) initiative. Live performances, in which opera singers perform from Gioacchino Rossini’s birthplace, as well as the immersive video “Dreaming Rossini”, were recorded and broadcast in VR format. The technical challenges included recording 8K 3D content using an Insta360 PRO 2 spherical camera, integrating ambisonic audio, and implementing the CTESquare platform for VR viewing. Adaptive Bitrate (ABR) technology ensured smooth playback even under unstable network conditions. The project results highlight the potential of VR to transform the enjoyment of cultural heritage, making opera more accessible and engaging to a wider public, especially for new generations. Immersive technologies have the power to preserve and renew operatic traditions, while simultaneously stimulating global interest.
