Properties Listed by Language
Requires Dolby-B decoding playback equipment.
Indicated on commercial recordings by the double D insignia (without indication of Dolby-C encoding). If Dolby is used on a tape recording without other indication, Dolby-B may be assumed. Despite the presence of the double-D or "Dolby" on a disc recording, this code is never used for commercial discs.
