Echo hiding: - Echo hiding technique is an efficient method to embed messages in an audio carrier (cover) signal by introducing an echo at various instances of the discrete signal. The advantages of this method include – high data transmission rate, superior robustness [9] and high noise immunity. Every echo produced from the cover signal can
