For this sound I turned the playback rate to 0.675

so that the sound lasted longer and I also added a

volume envelope so that the sound would come

in gradually then drop off nearer to the end of the

sound.

On this sound I edited the pitch, I also added a

volume envelope so that I could make the sound

be loud at the start, then fall off towards the

middle and then finally build back up at the end.

By taking away five semitones from the pitch it

made the sound a lot lower.

Here I added a pitch envelope so that I can make

the pitch of this sound gradually get higher as the

sound goes on.
