Echo-based data hiding algorithms are known to be very
popular in audio watermarking research. In this study, several echo kernels
such as single, bipolar, backward-forward, bipolar backward-forward and
time-spread, which are coded in Matlab, are compared in terms of robustness
against mp3 compression, imperceptibility and capacity. Mixer signals with
sinusoidal smoothing are used to improve imperceptibility. All kernels are
tested on the same audio database for a fair comparison. Importance of
parameters is discussed during comparison. Results show that bipolar
backward-forward echo kernel is more robust against compression and gives a
higher SNR (Signal-to-noise ratio).
