METHOD AND APPARATUS FOR CONTROLLING AUDIO FRAME LOSS CONCEALMENT |
摘要 |
Methods and related apparatuses control concealment for a lost audio frame of a received audio signal. A method for a decoder of concealing a lost audio frame includes detecting in a property of the previously received and reconstructed audio signal, or in a statistical property of observed frame losses, a condition for which the substitution of a lost frame provides relatively reduced quality. In case such a condition is detected, the concealment method is modified by selectively adjusting a phase or a spectrum magnitude of a substitution frame spectrum. |
