Sound
A live audio visualiser
In this lesson
Split sound into frequencies and give each one a bar. We build it live in about 16 minutes, then you change it in the Lab until it is yours.
Try this after
Change one number at a time and write down what it did. Most of the good surprises in this course come from the third or fourth change, not the first.

Keep going.
