Process
The XDR/SDR process involves many steps, the most prominent being:
- Duplication of the cassettes from a 1" wide master loop tape mounted in a loop bin duplicator (as opposed to standard cassette duplication using a 1/2" master loop tape), resulting in clearer high frequencies, greater bass response, and less noise.
- Recording a short test toneburst at the beginning and end of the program material on the cassette, to detect for any loss of audio frequencies in the audio spectrum. The toneburst consists of 11 tones about 0.127 seconds in length (with 0.023 seconds of silence in-between each tone), from 32 to 18,000 Hz. These tones are recorded on the cassette, and are read during the duplication process to detect if there is any loss of any audio information.
As well as with EMI & Capitol Records, PolyGram and other labels also offered cassette releases duplicated with the XDR process.

Famous quotes containing the word process:
“The toddler’s wish to please ... is a powerful aid in helping the child to develop a social awareness and, eventually, a moral conscience. The child’s love for the parent is so strong that it causes him to change his behavior: to refrain from hitting and biting, to share toys with a peer, to become toilet trained. This wish for approval is the parent’s most reliable ally in the process of socializing the child.”
—Alicia F. Lieberman (20th century)
“A designer who is not also a couturier, who hasn’t learned the most refined mysteries of physically creating his models, is like a sculptor who gives his drawings to another man, an artisan, to accomplish. For him the truncated process of creating will always be an interrupted act of love, and his style will bear the shame of it, the impoverishment.”
—Yves Saint Laurent (b. 1936)
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
