A Relative Phase Based Audio Integrity Protection Method: Model and Strategy

<div>The comparison of the simulation results of different audio processing and embedding methods. W: without processing; LP: smoothing/low-pass filtering; BP: band-pass filtering; MP (i): MPEG-1 compression (with compression ratio of 10.5:1); MP (ii): MPEG-1 compression (with compression ratio of 12:1); A/D: A/D conversion.</div>
