Exercise 1

The goal of this exercise is to create a web-based audio application using p5.js and its library p5.sound that processes a pre-recorded sound file, sending the processed audio signal to the computer’s speakers or audio output. Optionally, the user could also record the processed audio signal as a digital audio file on the computer’s drive.

Regarding the pre-recorded sound file, you should record in Audacity these two lines from the poem If— by Rudyard Kipling:

If you can dream – and not make dreams your master;
If you can think – and not make thoughts your aim;

The audio must be recorded at an optimal recording level without clipping

The recording must also be edited in Audacity, in order to remove possible silences at the beginning and end of the file. Finally, the recording must be normalized and saved as a WAV format, at 48 kHz and 24 bits.

Exercise 2

Audio steganography is the art of hiding data in an audio signal in an imperceptible manner.

Let us assume that you work at the UK Security Service (MI5) and, as an expert in audio steganography, you have to perform the following tasks:
