Task 3

The third task consists of creating a more sophisticated algorithm for embedding hidden messages based on the LSB audio steganography method (exercise 3.3). You will create an application in Python and use the audio file Ex3_sound5.wav to embed the secret message ‘Father Christmas does not exist’.

The application must include an algorithm that performs the opposite operation (i.e. an algorithm able to extract the hidden message embedded in Ex3_sound5.wav). You could, for example, to distribute the hidden message through non-consecutive audio samples using a random pattern, use more than one least significant bits to hide the secret data, etc.
