Laurence's Lab: wavetable oscillator synth
Pure Data was created primary to create and manipulate audio, so I spent some time trying to understand synthesis techniques and the basics of generating sound. After building a few things from tutorials (FM synths, filters, effects boxes), I started downloading patches (each program you build in PD is called a "patch") from the Pure Data forum where I'm a member. One of the patches I downloaded was a simple wavetable oscillator where you can draw your own waveform in the table. It was built by Dan Wilcox for his Robot Cowboy project.
Now, even I don't fully understand all the math and funky algorithms going on behind all that crazyness I built in the video. But thanks to how Pure Data works, I don't need to! I had alot of fun building the synth cause I could snap together different pieces (most of which I made previously) and see out it sounded.
