- The ICY guide explains that the metadata-length byte is multiplied by 16 to determine the following text block’s size.
Field notes
The guide distinguishes ICY’s in-band byte counting from HLS, where ID3 frames are placed at the head of transport segments. It gives common ICY interval values and explains that the byte following an interval indicates the metadata block’s length in 16-byte units. The page also names broadcast radio, retail audio systems, aviation monitoring, and game-world radio among the contexts where stream metadata is used.
