If you use the shifting method (Program 86) with a factor of 2.0 or 3.0, you’ll get the sound repeated or even triplicated. Why? Because in changeFreq2 you wrap back to the front to fill the rest of the sound. Can you fix it? Yes, you can change changeFreq2 to return a new sound of the correct length, instead.

What will be an ideal response?








Write shiftDur that takes a number of samples (or even seconds) to play the sound.
