Audio Visualization – Noises on my Window

I build an audio visualization based on four different audio files. The screen shows a series of light streams, and each of them is mapped to a specific audio file. The four audio samples were recorded at the window of my room from Thursday through Sunday. By examining each sample individually, it becomes evident the sample from Friday has the greatest stream. In contrast, the audios taken during the weekend have the dimmest light.

These are the audios:
