Disc Noise

Although CD technology is capable of providing the most noise free audio available today, noise may still be introduced in certain ways. Complaints of background noise (or skipping) should he addressed by first examining the disc for dirt, scratches, dust, or fingerprints on the bottom (opposite the label) surface.

Some noise may also be attributed to the recording technology. The sound quality is only as good as the original recording. Many early recordings of music works are limited by the technology of that time.

The following three recording technologies are listed in order of decreasing sound quality. Look for the symbol on the pull-out cover of the disc:
DDD - Digital session recording, mixing, editing and mastering.
ADD - Analog recording, digital mixing, editing and mastering.
AAD - Analog tape recorder used during session recording and subsequent mixing and editing; digital tape recorder used during mastering.
