EURASIP Journal on Applied Signal Processing 2003:10, 993–1000 c 2003 Hindawi Publishing Corporation Time-Scale Invariant Audio Data Embedding Mohamed F. Mansour Department of Electrical and Computer Engineering, University of Minnesota, Minneapolis, MN 55414, USA Email: mmansour@ece.umn.edu Ahmed H. Tewﬁk Department of Electrical and Computer Engineering, University of Minnesota, Minneapolis, MN 55414, USA Email: tewﬁk@ece.umn.edu Received 31 May 2002 and in revised form 22 December 2002 We propose a novel algorithm for high-quality data embedding in audio.
