Finding sound

After searching across multiple websites such as audiojungle.net, and freesound.org for royalty free music we found a variety of sound effects that we can use in our production. For example a police siren can be used to emphasise the presence of law enforcement, creating a false sense of security as the audience believe they will be able to help but they are later displayed to be incompetent.

Another sound effect we found is a bass filled 'swoosh' that may be used for our inter-titles as it emphasises the impact of each second that passes by, creating suspense as the audience await to see the conclusion when the time hits 0.

While editing we have searched for new sound effects that will fit with a short, high paced sequence, one we found is a very quick bass sound that will assist in building tension as it juxtaposes the high pitched building music that accompanies it.
