In this lab, various sounds were altered to do things like increase and decrease their volume, raise and lower their pitch, and play the sounds backwards.

The function used for this sound alters volume however you choose. I used this function to increase the volume of a bassoon playing the note 'g.'

The function used for this sound increases volume for the first part of the sound, and then decreases it. To demonstrate, I used a bassoon playing 'e.'

The function used for this sound takes a sound file and reverses it, so the sound will play backwards. I used the preamble to the Constitution to demonstrate.

The function used for this sound decreases the frequency, thereby slowing the sound and lowering its pitch. The sound used here is also from the preamble.

The function used for this sound increases the frequency, thereby speeding up the sound and raising its pitch. The sound used is a bassoon playing 'c.'
