The Dark Fader Remixer (com.wookiesoft.darkfaderremixer) on Google Play
This little application has a handful of sound samples taken from a single voicemail left for me by one of our Audio Engineers I work with who i affectionately call Dark Fader.From the left you can select the audio bed you want to use and then from the right choose any of the 8 sound samples to place over the top.Enjoy
