Verfahren zum Verschleiern von Fehlern in einem Audiodatenstrom |
摘要 |
The invention relates to a method for masking defects in a stream of audio data. Defects in a stream of audio data which was previously intact are detected and a spectral energy of a sub-group of the intact audio data is then calculated. After a model has been created for replacement data, based on the spectral energy calculated for the sub-group of intact audio data, replacement data is generated for defective or absent audio data, said replacement data corresponding to the sub-group, based on the model. |
