Question:

Try rewriting Program 100 so that you have a linear increase in volume to halfway through the sound, then linearly decrease the volume down to zero in the second half.

Data from Program 100

def increaseAndDecrease (sound) : for sampleIndex in range (0,getLength (sound)/2): value = getSampleValueAt (sound, sampleIndex) setSampleValueAt(sound, sampleIndex,value * 2) for sampleIndex in range (getLength(sound)/2, getLength(sound)): value = getSampleValueAt (sound, sampleIndex) setSampleValueAt (sound, sampleIndex, value * 0.2)
