Pipeline
For setting up the audios, I've followed the next pipeline:
1. The event or feature that triggers the sound has to be implemented in the last milestone.
2. Find the apropiated audio in a free audio library (I've used Soundsnap).
3. Ask for team feedback (change the sound if it's bad).
4. Set the sound in a soundbank (I've used Wwise for this).
5. Pre-implement the sound in a script (make a function that plays the sound in game).
6. Implement the sound (calling the previous function at the precise moment).
7. Ask for team feedback again (repeat the pipeline for that sound if it doesn't work).
