The invention discloses a method for carrying out digital conversion on steel wire recording, and relates to the field of steel wire recording digital conversion, which comprises the following steps of: step 1, preparing a digital conversion environment; step 2, performing installation and configuration of conversion equipment; step 3, preheating the playback device; step 4, installing a steel wire belt; step 5, adjusting and testing sound; step 6, collecting playing sound; step 7, storing the data; step 8, carrying out rewinding reduction; and step 9, finishing the digital conversion work. According to the method for performing digital conversion on the steel wire record, disclosed by the invention, high-efficiency and high-quality digital conversion work can be performed on a steel wireaudio file by utilizing an existing steel wire recorder, so that the playing frequency of the steel wire audio file is greatly reduced, and the existing steel wire audio file is protected to the maximum extent; moreover, the harmonic distortion of the sampled audio signal can be reduced, and the quality of the converted audio is improved.
Description
technical field [0001] The invention relates to the field of digital conversion of steel wire recordings, in particular to a method for digital conversion of steel wire recordings. Background technique [0002] In 1877, Edison invented the phonograph, which created a miracle in the history of mankind, allowing sound to be stored and reproduced; in 1898, the Danish scientist Paulson developed the first magnetic tape recorder, and exhibited Paulson's invention at the Paris Exposition in 1900. In 1937, Marvin invented an improved steel wire recorder, which has the characteristics of lifelike sound and beautiful sound quality. [0003] Steel wire recording used to play an important role in the field of audio archives in our country. Many audio files are still kept in steel wire tapes. Because of the long time and the aging of the steel wire itself, most of the steel wire tapes are currently on the verge of urgent rescue. There is an urgent need to digitize it. In the digitizati...
