详 情 说 明

In this document, we will discuss audio steganography based on Matlab, which is a technique used to hide secret information within an audio signal. Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. It is a technique used to protect sensitive information from being intercepted by unauthorized individuals.

Audio steganography is a subfield of steganography that involves hiding secret information within an audio file. This technique is often used in the field of digital forensics to investigate crimes involving audio recordings.

One of the methods used in audio steganography is the Discrete Cosine Transform (DCT). DCT is a mathematical technique used to convert a signal into its frequency components. By applying DCT on a digital audio signal, we can identify the frequency components that can be used to embed secret information.

Overall, audio steganography is an important topic in the field of digital signal processing, and its applications are wide-ranging. By understanding the techniques used in audio steganography, we can better protect sensitive information from being intercepted by unauthorized individuals.
