RuneAudio is a free and open source software with a specific objective: to transform an embedded platform (a cheap, silent and low-consumption mini-PC) into an Hi-Fi digital music player. It offers a lot of features and aims to be easy to use, flexible and future-proof.
Here’s what Andrea Coiutti had to say: “As many other open source projects, RuneAudio came out from personal needs: we all were using a laptop as digital source before, but we weren’t happy about absolute sound quality and ease of use. Our girlfriends didn’t like it either, as messing around with laptop and cables in the living room was dramatically lowering the WAF of our Hi-Fi systems”
