Plot spectrum to decode the message

This Python3 script deciphers a visual message encoded in an audio file using a provided noise file. It performs the following steps:

  1. Subtract the noise from the challenge audio file.
  2. Invert the resulting audio.
  3. Plot the spectrum of the inverted audio.

Usage

  1. Install Python 3 if you haven't already. You can download it from the official Python website.

  2. Install the required dependencies using pip, it is recommended to use a virtual environment for this. Run the following with the env activated:

pip install -r requirements.txt

  1. Run the script like:

python plot_spectrum_with_message.py

The script takes the files Challenge.wav and WhiteNoise.wav provided in this repository as defaults, but those can be provided as params too like:

python plot_spectrum_with_message.py /path/to/challenge/file /path/to/whitnoise/file

  1. Decipher the message plotted in the spectrum.
