Igor Vasiliev has released SoundSaw, a complex sound processing app for iOS 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. They say:
Depending on the settings, it can add light distortion and saturation to the sound for a more natural and lively sound, or drastically change the sound and make it as loud and harsh as possible, full of all kinds of harmonics, crackles and rattles. The settings of this app provide great opportunities for experiments with sound destruction.
All controls are located on a single screen, grouped by function into six sections with a plain way of signal path from the first section "Input" to the last section "Output". The chain of individual effects in this app is designed in such a way as to get the most interesting result for any parameter values in the widest possible range.
