Packet Loss Concealment for Audio Streaming Based on the GAPES Algorithm

In this work we present a novel approach for audio packet loss concealment, designed for MPEG-Audio streaming, based only on the data available at the receiver. The proposed method is based on the GAPES (Gapped Amplitude and Phase Estimation) algorithm for replacing the missing data, using interpolation in the spectral domain. Since the MPEG standard uses MDCT for compression, we need to convert the data to the DFT domain. This conversion is done directly using an efficient procedure that we developed for this purpose. This technique is found to provide better performance than previously reported works, and can be successfully used even with a loss rate of 30%.
