Sound as a Pound Mate!

Just been messing around with recording my voice in the College studio using the basic recording equipment and editing software. The software that I was using was called Audacity which is a basic recorder/editor for sounds and is very simple to use, I was using was a SM 58 Microphone that connected into a XLR cable which connected into a basic Mixer and went straight into the computer so when I said something into the microphone you could hear it in the headphones. what I practiced doing was recording me letting out a little shout or some weird noise then changing it by adding echos or making it delay.
