在检测出误码后,应采取必要的补偿与校正措施,否则误码将引起噪声,对音质影响甚大。误码补偿有三种:(a)抑制法,即把错误字码抑制至0,这样可以避免产生大幅度的误差脉冲。(b)前值保持法,顾名恩义,这是把错误字码前面的字码保留起来,代替错误,这样就不会发生很大的音频差异了。试听表明,这种方法能大大降低误码对听觉的影响。(c)线性内插法,又叫平均值插入法,错误字码将 After detecting the error code, should take the necessary compensation and correction measures, otherwise the error will cause noise, a great impact on the sound quality. There are three kinds of error compensation: (a) Suppression method, that is, the error code is suppressed to 0, so as to avoid generating a large error pulse. (b) The previous value hold method, given its name Enyi, preserves the code in front of the error code instead of the error so that no significant audio difference occurs. Audition shows that this method can greatly reduce the impact of error on hearing. (c) Linear interpolation, also known as average insertion, the error code will be
