What is phase coding in audio Steganography?

What is phase coding in audio Steganography?

Abstract: Steganography is used to embed secret messages in cover media. The proposed algorithm is based on the phase coding technique which embeds data in the phase spectrum of the frequency domain signal. …

How do you do audio Steganography?

Audio Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. It is the science of hiding some secret text or audio information in a host message. The host message before steganography and stego message after steganography have the same characteristics.
