Take a look at the last post I did (link). See that video? Now check out the video above. I took the same sounds and put them into the Borderlands granular synthesis app. From a retro melody using analog hardware futuristic noise. I think it starts to get good around the 2:15 mark.
“Granular synthesis is a basic sound synthesis method that operates on the microsound time scale. It is based on the same principle as sampling. However, the samples are not played back conventionally, but are instead split into small pieces of around 1 to 50ms. These small pieces are called grains. Multiple grains may be layered on top of each other, and may play at different speeds, phases, volume, and frequency.” – Wikipedia
