I am teaching myself how to read in wav files into C++ as a part of me learning C++. I have found many resources online that recommended the following library: libsnfile lib
I fixed the issue. For future readers, this is a very common problem, I think. I placed the .dll in the debug folder of my Visual Studio project. Visual Studio couldn't see the .dll file otherwise. After this, the program fired up as expected and ran. If this does not fix the issue for you, then I suggest something else could be going on.
