 * DECLICKING : in reprocessing sounds from an old 78-r.p.m. recording, the process of eliminating the noises or "clicks" pro­duced by groove irregulari­ties, by manually or elec­tronically removing them from the tape made from the old recording.
 * DECODING : transforming information from a form suitable for trans­mission to a form suitable for use. Frequently used in reference to quadraphonic recordings, which require an electronic "decoder" for playback.
 * DOLBYIZED : refers to a recording pro­cessed through a particular noise reduction device (a "dolby"). The dolby achieves noise reduction by raising the volume of quiet passages while recording and lowering them to proper levels while playing back.
