This chapter proposes two data-hiding algorithms for stereo audio signals. The first
algorithm embeds data into a stereo audio signal by adding data-dependent mutual delays …

We extensively evaluated a data hiding algorithm for stereo audio signals which embeds
data using the polarity of the echoes added to the high-frequency channels, which we have …

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 …

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 data hiding algorithm for stereo audio signals which embeds data using the
polarity of the reverberations added to the high-frequency channels. We replace the high …

This chapter provides a general overview of audio data hiding. The general issues are
discussed first, followed by the basic techniques used to hide data in audio signals …

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 …

Data hiding is a group of techniques for embedding data in media such as images and
audio signals. Ideally, the data will be directly embedded into the data stream of the host …

Echo hiding is one of the prevailing techniques in audio hiding. Current available echo
hiding techniques still have some drawbacks, the detection ratio is relatively low, the simple …

In this paper, a novel bipolar time-spread (TS) echo hiding based watermarking method is
proposed for stereo audio signals, to overcome the low robustness problem in the traditional …
