About source code examples

My goal is to teach audio DSP principles in a way that is more intuitive than most available material. And part of that goal is to help you to think about the your goals and how to solve them by showing you my thought process.

So at one extreme, source code shouldn’t be part of what I’m doing here—ideas over implementations. However, examples are a powerful learning tool, and I want to show that the principles introduced here are practical. But the other extreme is to develop a full open-source library here, and that’s something different entirely. Foremost, it conflicts with what I’m trying to do here—even if I had time to do both. My goal with source code is to give you minimal, but commercial-grade examples in source code. Something lean enough for you to dissect and see the principles applied.

For example, the WaveTableOscillator object is a high-quality DSP component—good stuff. But it’s not exactly how I would write it for myself for a major project. In addition to the WaveTableOscillator class, which doesn’t create the wavetables themselves, I might write a wavetable class that does, and a manager class that would use the two classes, keeping track of oscillators and sharing common wavetables between them to save space and time. And I might use C++ templates. And asserts for trapping bad parameters at development time. But in the context of this blog, these things tend to obscure the functionality that I’m trying to focus on.

I’m getting ready to lay more source code on you in coming articles. I think that working C++ code, that you can experiment with, is better than using pseudo code, and I’ll continue in that direction for now.
