2. Digital watermarking of stereo audio signals The spatial localization of sound sources in
HAS is known to depend on both amplitude and phase characteristics for low frequency, but …

We propose a watermarking algorithm for stereo audio signals which embeds data using
delay values of the high-frequency channel signals. Since the stereo image perception of …

The authors propose a watermarking algorithm for stereo audio signals which embeds data
using delay values of the high frequency channel signals. Since the stereo image perception …

In this paper, we propose a non-blind audio-watermarking scheme based on compression-
expansion of stereo signals. We also demonstrate the general methods for embedding …

Audio watermarking techniques are used to embed extra information, typically relating to
copyrights, into audio signals. In some applications, embedding of multiple watermarks in a …

In this paper, a novel non-blind audio watermarking scheme is proposed. The method
makes use of both channels of stereo music signals. The signals are divided into segments …

This paper presents a robust, stereo audio signal watermarking algorithm. The inter-channel
redundancy of stereo audio signal is exploited by calculating average and difference signals …

A non-blind two-channel time-frequency digital bits audio watermarking scheme with error-
correcting code is described in this paper. The proposed method operates by encoding the …

A data hiding algorithm for stereo audio signals is proposed, which embeds data using the
polarity of the reverberations added to the high-frequency channels. The high-frequency …

Based on the requirement of watermark recovery, watermarking techniques may be
classified under one of three schemes: non-blind watermarking scheme, blind watermarking …
