DeepSound

DeepSound is a security application that helps you protect any files, regardless of their type, by embedding them into WAV or FLAC audio tracks. It offers support for password protection.

The installation procedure does not take a long time to finish. As for the interface, DeepSound adopts a normal window with an Explorer-based folder structure for navigating directories to locate carrier files.

Once you have selected a carrier WAV or FLAC audio track, you can select the files to hide using the drag-and-drop method, and examine the output size to make sure it does not exceed a particular value.

Output settings can be configured when it comes to the saving directory, password protection (with AES 256-bit encryption), and audio quality (low, normal, high). The new carrier file can have the same format as the original, or it can be exchanged for FLAC or WAV.

The tool take a while to read carrier files but embeds the files pretty fast while remaining light on system resources. It did not hang, crash or pop up error messages in our evaluation.

Unfortunately, it failed on a couple of occasions to create the new files in our evaluation, although it did not indicate any error (when we attempted to convert the audio track to another format and to encrypt the files). On top of that, DeepSound is not that intuitive when first running it, and it does not integrate an option for modifying the output file name.
