WavSteg

WavSteg is a steganographic tool written in C that embeds files within WAV audio files using least significant bit (LSB) steganography techniques. The program accepts two command line arguments: a path to a WAV audio file and a path to any other file type. It modifies the WAV file by encoding the contents of the second file into the LSB portions of each audio sample, effectively hiding data within the audio file. The tool overwrites the original WAV file with the modified version containing the hidden data. The capacity for hidden data depends on the audio file specifications - for example, a 300-second WAV file at 44100 samples per second with 16 bits per sample for stereo channels can hide approximately 300 * 44100 * 2 * 1 bits of data when using one LSB per channel sample. WavSteg operates as a command-line utility and requires the target WAV file and the file to be hidden as input parameters. The steganographic process modifies the audio data while maintaining the file's playable format.
