Reiterative isolated independent transfer comparison methodology for audio preservation quality control

摘要

The purpose of this invention is to provide an efficient methodology for ensuring that a sound transfer from one medium to another has been performed according to a set of quality standards. Current methods of quality assurance take into account the calibration of the equipment in ideal conditions, but do not take into account the physical condition of the media or errors that may have occurred when the media was originally recorded. This invention quickly and elegantly confirms that a “preservation transfer” meets quality standards by comparing it to a short test “evaluation transfer” that is performed independently of the preservation transfer on a second system isolated from the primary system. The comparison can be made by a human or by computer software. Equipment problems, media problems, or engineer mistakes are quickly discovered and eliminated using this methodology, whereas without this invention, these same issues could go undiscovered.
