It may just be a limitation of the slides rather than the full presentation, but this is almost entirely about the audio synthesis side. There is nearly nothing specific to GPUs or shaders that I can see.

So fair warning: if, like me, you already know the fundamentals of audio and synthesis (and it starts with "what's a sine" and "how does 440Hz map to a piano), but were interested in the shader part, there's not much here for you.

The reason is there isn't much special about his use of shaders. The first two slides cover shader specific details (write to a 1D render target where each pixel is a 44khz sample). The audience is people who are familiar with fragment shaders, and specifically familiar with shadertoy, but with limited exposure to additive synthesis.
