Title:
低遅延の統合されたスピーチ及びオーディオ符号化におけるエラー隠しのための装置及び方法
Document Type and Number:
Japanese Patent JP5849106
Kind Code:
B2
Abstract:
An apparatus for generating spectral replacement values for an audio signal has a buffer unit for storing previous spectral values relating to a previously received error-free audio frame. Moreover, the apparatus includes a concealment frame generator for generating the spectral replacement values, when a current audio frame has not been received or is erroneous. The previously received error-free audio frame has filter information, the filter information having associated a filter stability value indicating a stability of a prediction filter. The concealment frame generator is adapted to generate the spectral replacement values based on the previous spectral values and based on the filter stability value.
