Method and device for solving sound distortion problem of sound playback and recording device

摘要

A method and a device for solving the sound distortion problem of a sound playback and recording device are used to avoid the data overflow phenomenon when the sound playback and recording device performs conversion between analog and digital formats. At least a gamma table is used to adjust the amplifications to avoid the signal overdrive phenomenon when the sound playback and recording device records sound. Similarly, when converting a digital sound signal back to an analog sound signal, a gamma table is referred to for adjusting the amplifications. The signal overdrive phenomenon can thus be effectively solved to reduce the probability of sound distortion of the sound playback and recording device when a digital sound signal is restored into an analog sound signal.
