Igor Vasiliev has updated their SoundSaw - The Art of Sound Destruction app for iOS to version 1.1. They say:
SoundSaw is a complex sound processing app with easy-to-use controls designed to distort the sound of musical instruments or voice, and give the sound the aesthetics and atmosphere of noise, lo-fi, chiptune and experimental music scene.
This update contains some sound engine improvements and optimization, additional audio hardware options for standalone mode, and several new presets. For details on the new options, see the built-in app description. A full description of the app is also available as a PDF file on the application website.
