Problem
Write a function to input a sound, then create a canvas sound of the same length. Copy samples from the input into the canvas every third position, i.e., copy from index 0 in the input into the canvas at index 0, then copy from index 3 (skipping index 1 and 2) in the input into the canvas at index 3. What do you hear in the canvas sound? Same sound? Faster? Slower?
