Summary

Description
English: Spectrogram of XDR toneburst followed by pseudo-DTMF dualtones used by XDR to uniquely identify an album. Created using Audacity from the audio of a YouTube video playing the cassette “Cinéma Vérité” by Dramarama published by Chameleon Records in 1985. Note that because it is from YouTube, any tones higher than 16kHz have been cut off which affects the XDR tone burst. However, the DTMF tones are correct and spell out *DD774819B.
