XDR (audio) - Process

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:

    Opinions are formed in a process of open discussion and public debate, and where no opportunity for the forming of opinions exists, there may be moods—moods of the masses and moods of individuals, the latter no less fickle and unreliable than the former—but no opinion.
    Hannah Arendt (1906–1975)

    A process in the weather of the world
    Turns ghost to ghost; each mothered child
    Sits in their double shade.
    A process blows the moon into the sun,
    Pulls down the shabby curtains of the skin;
    And the heart gives up its dead.
    Dylan Thomas (1914–1953)

    That which endures is not one or another association of living forms, but the process of which the cosmos is the product, and of which these are among the transitory expressions.
    Thomas Henry Huxley (1825–95)
