Is there any methods to set a sound files frequency? I am trying to create a piano and this works as it should work. However, I miss one note that is D#, but I can not find any D# sound from internet that would match the ones I am currently using. So is there any possibility to use one sound file, and then tone it's frequency up with code?
It would be also cool if this worked, I could make octave buttons and play piano from any octave and not just from the original (that's used in the sound files).
