its made with acid music studio 8, there are about 15 layers of different samples and downloadable effects in there. the girl's voice is about 6 different girls voice samples mixed together to make the little loop of her voice. some are reversed to make it blend better. took about an hour to piece together. I didn't go out and record all the samples if that's what your asking. but I put the song together with samples provided for making synth dubstep songs.
