%X One of the key challenge of audio information hiding is real-time signal processing. Although echo hiding has dominance in transparence and robustness, the complexity of extracting information make it impossible to meet real-time requirements. Put forward a fast algorithm that settle the problem. In the case of N-samples sequence, the peak value of the fast algorithm is 1/N of that of the old one, and total instructions of the new one is about 30% of that of the old.
