Abstract (en)
[origin: WO0143120A1] The invention relates to a method for decoding digital audio data. The inventive method is used for concealing errors according to an error number, whereby the past is also considered. According to the invention, equaliser values are detected (13) by means of which the received digital audio data is dequantised (3). The equaliser values are stored or calculated. A muting is activated when the error number exceeds a predetermined greatest threshold value. Equaliser values are not used for dequantisation when the error number is below the smallest predetermined threshold value.
