Audacity
For this sound assignment, I downloaded an acoustic guitar melody from freesound.org. I picked this audio for its smooth mellow beat Audacity was used to edit the audio with an effect of an AUPitch and AUMatrixReverb. It was pitched down and the reverb added so the sound now has a heightened sense of drama. I can imagine something like this being used in a serious advertisement or movie trailer as background music.
