I want to do a project on sound programming, but I don't know where to start

Question

At my high school we can take a class where we basically learn about a subject on our own for a semester. I was thinking that I want to learn about "sound programming," but I realized that I have no idea what that entails. I'm interested in learning about, for example, how a synthesizer works, how I could write a VSTi, and how sound works in computer science. Is this a feasible subject? Are there any good tutorials out there for somebody completely new to this? Any tips or suggestions would be greatly appreciated.

Edit: This is the sort of thing that I'm interested in.

VST plugins are normally written with C++. But it's possible to use other languages as well. Building a VST plugin with C++ is quite an involved project. Without pre-existing experience it's probably too much for a school project. Additionally you'll probably spend as much or more time implementing the VST part and GUI as you will actual sound programming.

However there are a other ways to create a VST plugin and still get your hands dirty writing code.

SynthEdit is a modular environment for creating synthesizers and effects. Modules such as oscillators, envelopes etc are connected visually with wires. Patches can be exported as VST plugins. SynthEdit allows additional modules to be programmed with C++.

SynthMaker is another option similar to SynthEdit. It features a code module which allows you write DSP code without the difficultly of compiling modules in another language.

The advantage of using SynthEdit or SynthMaker in your situation is that you can focus your programming efforts on a particular area, such as creating a filter or oscillator module. SynthEdit/SynthMaker can then handle the other areas (GUI, voice logic, etc).

Using SynthEdit or SynthMaker will also allow you to prototype ideas quicker. So you will have more time to experiment with different synthesizer or effect architectures before settling on something to complete for your school project.

DSP theory can be quite involved and maths heavy but that alone shouldn't put you off. Depending on what you want to do, a basic understanding of digital audio principles and algebra level maths may be enough to take you a surprising long way.
