Which tool hides secret data in WAV/FLAC, can extract from audio CD tracks, and encrypt secret files?

• A. OmniHide Pro
• B. DeepSound
• C. GiliSoft File Lock Pro
• D. Spam Mimic

Answer: (A)

This question tests audio steganography with encryption and CD data extraction. The best tool is described as capable of hiding secret data inside WAV or FLAC audio, extracting payload from audio CD tracks, and encrypting the hidden files. That combination—concealing data in lossless audio formats, being able to retrieve it from CD track sources, and applying encryption to the hidden payload—matches OmniHide Pro’s capabilities. Other options don’t fit all three aspects as cleanly. DeepSound does audio steganography and can password-protect hidden data, but it isn’t specifically noted for extracting from audio CD tracks. GiliSoft File Lock Pro focuses on general file encryption and access control rather than hiding data inside audio or CD extraction. Spam Mimic isn’t related to steganography or encryption at all.
