How does it work:
Press all the number keys from 1 to 8 and watch the patterns move and change to familiar sound logos!
(For some reason there are problems when Safari is used to view my project so please use Chrome or Firefox!)
In my proposal, I wanted to do some sort of sound visualization either in a form of a game or something similar to patatap. Sticking to my proposal, I used some iconic sounds that can be recognized through our day to day usage of technology. I realized how easy it is to overlook the importance of how these sounds inform our usage of technology so I ended up creating a sonic art piece that creates patterns according to the amplitude measured through the sound files.
My final project does not quite achieve the level of fidelity I originally intended my sonic art to have as the visuals are a bit too noisy and I want it to have a simple yet sophisticated look. I spent quite a bit of time trying to figure out how to use sound libraries in p5.js and mapping the amplitude to each of the various patterns, so I had a bit of difficulty debugging the whole code.
