Annoydio vs skippodisk

Annoydio has a grid of pads which you can assign, manipulate, and play sounds. There are several built in sounds you can assign to any of the pads. In the Library you can create your own custom sounds using your device's microphone. You can also add custom sounds through iTunes file sharing. You can manipulate the sounds by changing the frequency, playing in reverse, looping, adding effects such as distortion and delay. You can also change parameters such as attack, decay, sustain, and release. You can connect a MIDI keyboard and play the current sound with full polyphony. On the iPad version there is a popup keyboard. Annoydio also supports Inter-App Audio as a sound module and MIDI device. You can use Annoydio as an instrument to add beats or effects to songs in apps like Garage Band. Short demonstration video here http://www.youtube.com/watch?v=EzuQhLxMxeM

skippodisk is a free AUv3 plugin and standalone app. It features algorithm that imitates compact disc reading errors and adds feedback for some comb filtering. controls: * main control is a 2-dimensional slider that changes delay time / buffer size using value on X axis and feedback (positive and negative, -0.997 to 0.997) on Y axis. This control adds some creative comb-like effect. * algorithm settings: 
[ auto ] enables automatic cd skipping. 
[ dropout ] enables adding silence. Use both [auto] and [dropout] with zero feedback value (in the centre of touch control) to achieve the effect of a CD audio glitch * [ bypass ] control and volume control. This slider is in low value state by default.
