1. The software we used to create our documentary was Garageband
With the beginning of our radio trailer we started off by adding in our voice
recording and sound effects to introduce the trailer, in between most sound
recordings we are planning to add a sound effect to separate them

2. We used a few sound clips from the documentary itself to help promote it
even further, the clips also help add to the importance of the topic we have
for our documentary.

3. One of the conventions for a radio trailer is to have a fading out echo at the
very end, we created this same effect by copy and pasting a sound clip and
making it quieter each time
