DeepMP3 is described as 'Can encode and decode text messages inside MP3 audio files' and is an app in the security & privacy category. There are three alternatives to DeepMP3 for Mac, Windows and Linux. The best DeepMP3 alternative is DeepSound, which is free. Other great apps like DeepMP3 are SilentEye and The Hider.
DeepSound is a steganography tool and audio converter that hides secret data into audio files. The application also enables you to extract secret files directly from audio files or audio CD tracks.
SilentEye is a cross-platform application design for an easy use of steganography, in this case hiding messages into pictures. It provides a pretty nice interface and an easy integration of new steganography algorithm and cryptography process by using a plug-ins system.
