Level Up: Creative Coding with p5.js – part 8
In our last session, we will learn how to create audio visualizations with the p5.sound.js library. We will start by learning how to upload and play a sound file in the p5.js web editor. We will first talk about what amplitude is and how we can program a p5.js sketch to react to the amplitude of a sound file. We also talk about how to analyze sound with Fast Fourier Transform (FFT) and we can use the amplitude values along the frequency spectrum to create an audio visualization.
Here are some Stack Overflow questions related to the work we did in this session:
Creating a Sound Wave using P5.js
( p5.js ) FFT report lower frequencies “too loud” and higher frequencies “mute”?
