Windows API (one of) to resample audio is Audio Resampler DSP. This transform class is pretty straightforward to set up input and output types, then push input data and pull output.

Another task you would possible deal additionally with is reading from file and writing into a new file (you did not specify if it is actually needed in your original description though).

You might also want to use third party libraries like NAudio.
