spectrology – Basic Audio Steganography Tool

spectrology is a Python-based audio steganography tool that can convert images to audio files with a corresponding spectrogram encoding, this allows you to hide hidden messages via images inside audio files.

Using this tool you can select range of frequencies to be used and all popular image codecs are supported.

Usage

usage: spectrology.py [-h] [-o OUTPUT] [-b BOTTOM] [-t TOP] [-p PIXELS]
                      [-s SAMPLING]
