No background music. Keep in mind that these are all samples from a show and there is only so much you can do with modifying audio that's not an actual instrument. This was an experiment I did, more like a trial and error where I was mixing monophonic/efficient pitch, equalizers and vibrato in Vegas. Audio frequencies cancel each other out with the bgm so I had to modify some of the volume levels.
Audio cracks are due to sentencing in Vegas.
Also I left the equalizers on at some parts, but I don't want to re-render this again.
