This paper describes packet loss concealment methods for MP3 audio. The proposed methods are based on estimation of modified discrete cosine transform (MDCT) coefficients of the lost packets. The estimation of MDCT coefficients of lower dimensions is performed by switching two concealment methods: the sign correction method and the correlation-based method. The concealment methods are switched based on redundant side information calculated subband-by-subband for reducing MDCT prediction errors. Next, a method for improving estimation of MDCT coefficients of higher dimensions was proposed. The method estimates the absolute value and sign of an MDCT coefficient independently. The subjective evaluation experiment proved that both of the improvement methods for lower and higher dimensions effectively improved the subjective audio quality.
