Steganography is employed in the study and application of techniques that allow hiding messages or objects inside other imperceptible objects, called carriers. Hence, such a procedure tries to hide messages within other objects to establish a covert channel of communication, becoming the act of communication unnoticed by observers who have access to that channel. In this work steganography is used to send audio messages, covered by another audio message, using techniques of phase inversion of an audio signal.
