Audio Steganography

Audio Steganography:

• Hides messages in audio files using LSB encoding
• Modifies least significant bits of audio samples
• Imperceptible to human hearing
• Can hide text or binary data

LSB (Least Significant Bit) Method:

• Replaces LSBs of audio samples with message bits
• Each audio sample can hide 1 bit of data
• Changes are virtually undetectable by ear
• Requires audio file processing for real implementation

Capacity Calculation:

• Depends on audio file size and sample rate
• CD quality (44.1kHz): ~44,100 bits per second
• MP3 quality: ~128,000 bits per second
• Lossless formats: Higher capacity

Security Note:

• Steganography is not encryption
• Messages can be detected with analysis
• Combine with encryption for security
• Consider watermarking for copyright protection

Applications:

• Copyright protection and watermarking
• Covert communication channels
• Data hiding in multimedia files
• Digital forensics and steganalysis

Note: This is a simulation. Real audio steganography requires actual audio file processing and manipulation of audio sample bytes.
