An Analysis Of The Influence Of The Speed Stability Of The Tape Recorder On The Sound

Since the invention of the tape recorder in the early twentieth Century,it has been widely accepted and widely used by the public.However,with the popularization and application of computers,and the advent of the digital era,the tape recorders is used less and less.There are a large number of valuable historical audio data waiting to be digitally restored.On the basis of the analog tape recording and audio repair technology,this paper elaborates the "Chinese folk song integration,Guangxi volume" in the process of repairing the history of the related audio problems.In this paper,the influences of the change of the transmission speed of the tape machine on the sound and the post-processing are mainly studied and analyzed.This thesis is mainly divided into 3 parts.The first part describes the analog recording and digital recording,and the working principle of the tape recorder.The second part analyzes some problems of audio tape in the past.The third part is about the problems and solutions in the process of the restoration of historical audio in the integration of Chinese folk songs,Guangxi volumes.It focuses on the analysis of the impact of changes in transmission speed of the tape machine to sound and its later repair,and then it explores the similar historical data in the general method of audio ripping and repair technology,and then it provides a reference to the later restoration of audio data.
