So I wrote a post about creating basic beeping sounds in C# a few months ago:
Well, someone asked me if I could make the source code available. Well, because I’m a nice guy, I’ve cleaned up the project and uploaded it here:
You will need Visual Studio 2010 or newer to run the project as-is. I have not tested it in Mono, and I do not guarantee that it will work in Mono. The code is offered AS-IS WITH NO SUPPORT.
If you find the project useful, please make a video response to the YouTube video with your creation.
