In the video there's seems to be a tinny sound to the heart beat but this is because of the compression to the video to be uploaded to my blog and is not a true reflection of the audio.
I then recorded the played trigger event with Fraps as evidence that it works in my level; however the sound is only a rough draft and not the end piece as this is just a test.
I put all the pieces of audio together in Adobe Audtion and did a rough draft if you will of the piece of sound to be played on the trigger event and exported it making sure it was a 16 bit wav file. I then imported it in to UDK and set up a trigger, Kismet and a Matinee to make sure I could do this.
