About This Station

**AC3X Radio** is an Italian internet radio station dedicated exclusively to classical music, presented as "a classical surround experience." Its defining feature is a 5.1.2 immersive sound format, with live streams available in OPUS 5.1.2, AC3 5.1, and AAC 5.1, designed to recreate a concert-hall experience at home. The station broadcasts in English and draws its programming from original live performances and high-quality recordings sourced from public domain, creative commons, copyleft, and royalty-free material, all specially remastered using a proprietary spatial upmixing protocol. Founded and engineered by Marco Coldagelli, the project is free to use and targets listeners with multichannel sound systems, though it can also be played on compatible TV boxes, smart TVs, and internet radios.
