Abstract
A method of packet loss concealment in an adaptive differential pulse-code modulation (ADPCM) codec with a packet loss compensation (PLC) circuit is provided. The method provides a predetermined transition period between a correct signal (x) and a substitute signal (x) and a difference (d) between the substitute signal (x) and a computed prediction signal (x) is combined with a dequantized prediction error (d) to receive a dequantized combined prediction error (d) which is added to a predicted signal (x) to provide a combined transition signal (x) as basis for an output signal (x−x) during the predetermined transition period for adapting all decoder parameters.
