Sprak is a noise app, noise as in crackles and phat distorted drones.
Sprak is an instrument for people who loves to experiment with noise.
Sprak was born out of a need to play with evolving noisy noise while riding the train.
You could also make sounds that sound a bit like hypnotoad.
Still not decided if you should shell out .99cents for this most awesomely awesome glitched out noised curcuitbentish app? check out the soundexamples over at http://www.tinkerteam.se/?page_id=87
