A data recognition and replacement method for dat missing audio

Abstract

The invention discloses a data identification and replacement method of digital audio tape (DAT) missing audio. The data identification and replacement method comprises recording a tape twice by using a DAT re-recorder, obtaining main files and auxiliary files, aligning the auxiliary files to the main files, searching sample sections matched with the sample sections of each main file in the auxiliary files, obtaining the matching relation of the sample sections of the main files and the auxiliary files, analyzing the matching relation, obtaining available the sample sections of the main files and the available sample sections of the auxiliary files, writing the sample sections of the main files in a new file in sequence, writing the available sample sections directly in the new file, replacing unusable sample sections with the available sample sections of the auxiliary files matched with the unusable sample sections and writing the available sample sections of the auxiliary files in the new file. The new file is a file repairing the DAT missing audio. The data identification and replacement method of the DAT missing audio is high in identification capacity on the missing audio in a recorded audio file, and the DAT missing audio is effectively repaired through the replacement method.

Description

technical field [0001] The invention relates to a method for identifying and replacing data, in particular to a method for identifying and replacing missing audio data. Background technique [0002] AudioDAT is a professional-quality standard medium and technology for digital recording on magnetic tape. [0003] An AudioDAT device is a digital tape recorder. Most AudioDAT recorders are capable of recording at 44.1 kHz, the CD audio standard. DAT has become the standard archiving technique in professional and semi-professional environments where recordings are mastered. [0004] The AudioDAT transcription machine undergoes an analog audio signal conversion during the transcription process. Due to its inherent defects, the transcribed audio data will be disturbed by the noise generated during the transcription process, and when the AudioDAT transcription machine transcribes the data, it will randomly generate small segments. Distortion, loss, etc. The noise interference, di...

AI Technical Summary

Problems solved by technology

The inevitable data loss and distortion in the transcription process seriously affects the cultural characteristics and sound quality characteristics of the transcribed digital audio files

[0005] Due to the current DAT technology has gradually withdrawn from the market, this DAT transcription machine has been discontinued, and the manufacturer no longer provides technical support, so it is impossible to repair the digital audio obtained by transcription on hardware

However, if you go to a foreign specialized repair organization to repair it, the cost will be very high.
