摘要： A method of decoding digital audio data is described; it is used to implement error concealment as a function of an error count in which the preceding data is also taken into account. Therefore, equalizer values, through which dequantization of the received digital audio data is implemented, are determined. The equalizer values are either stored or computed. If the error count is greater than a predetermined highest threshold value, a muting is activated. If the error count is less than the lowest predetermined threshold value, no equalizer values are used for dequantization.
