NCAA Strategies has come up with the great idea to compile all the real life sounds for each NCAA team for use with the stadium sounds feature in NCAA Football 09. Broken down by conference in the forum you can find every team and situation that is customizable and the specific music/sounds that correspond to them. This will be the place to get everything you need to utilize the feature and most accurately represent each team.
If you’d like to contribute with your knowledge of what is heard in the situations and/or MP3 files than drop in and add to the collection here. You can also read through some added specifics from the dev team here.
