Rockbot is the highest fidelity streaming commercial music service on the market. We do not compress, manipulate, or adjust our music files from the labels before our final format.
We are currently using a pressure balanced, stereo, 64 bit AAC in MPEG4 audio
compression. This is the same output with HDMI or Line-level audio out on our
players. To quickly test fidelity feel free to connect to a home theatre system with HDMI.
