Rewrite increase volume so that it takes two inputs: a sound to increase in volume and a multiplier. Use the multiplier as how much to increase the amplitude of the sound samples. Can we use the same function to both increase and decrease the volume? Demonstrate commands that you would execute to do each.
What will be an ideal response?
```
def increaseVolume(sound, multiplier):
for sample in getSamples(sound):
value = getSampleValue(sample)
setSampleValue(sample ,value * multiplier)
```
Yes you can use the same method to increase and decrease the volume. Values above 1 will increase the sound, while values below 1, but above zero will decrease the sound.
Increase Sound: increaseVolume(sound, 2)
Decrease Sound: increaseVolume(sound, 0.5)
