In the series "Mr. Robot," the main character uses DeepSound application for the Windows, running in a virtual machine in order to hide the information collected on the disks with music albums. Set audiophile-Steganography is not limited to this program, there are others with similar functionality:

• AudioStegano,
• QuickStego,

We look at an example of using DeepSound. Typically, hackers are working on Linux, but the mask files can be in any of the versions of Windows.

First you need to download the application from the official site DeepSound.

Install the application. Antivirus can be indignant, but in the installation file has no viruses.

Using the program is simple: in the lower left corner shows the directory to save the ready files, there are buttons for adding audio files, confidential documents to implement, encryption key and the extraction. DeepSound can also be used to convert audio in various formats.

In the top list of the audio files are added - carriers of secrets in the bottom list contains files you want to hide.

In the upper right corner of the application there is a button "Settings» (Settings). In this menu, you can select the directory default save (Output directory), where you can also change the color theme and language (English and Slovak).
