Question: Hi Justin! I have a wav file with Note C (guitar sample) and I want to change it to C#. How to implement it in code?

If you don't mind changing the length, you could use WDL_Resampler to adjust the rate, i.e. rs.SetRates(srate,srate*pow(2.0,-1.0/12.0)).. There would be a lot of code to read/write .wav files, etc, though. If you want to keep the length the same, you could use SoundTouch and use a pitch adjustment of a similar amount.
