Famous among fidelity-obsessed streamers, Radio Calico built its name on high-resolution audio — its flagship feed runs as 24-bit/48kHz lossless FLAC, and this 192 kbps MP3 version carries the same programming in a lighter stream. The US station is ad-free, listener-supported and human-curated rather than algorithm-driven, mixing familiar hits from across the decades with newer rock and pop discoveries. It took its eclectic, quality-first format to a global online audience in October 2023.
