Developer Paul Adams has introduced SoundMashine – a granular synthesis based sound sampling and sequencing instrument.
The app records sound using the devices built-in microphone, then divides the sound into slices which are then automatically assigned to each of 16 screen tiles.
Each tile has its own set of parameters allowing you to adjust window size, playback rate, pitch, feedback, delay and delay modulation, all of which are set by the swipe of a finger. Each parameter listed can also be randomised between a set of assignable values.
Using the sequencer function patterns of tiles can be recorded and played back at different speeds, again using simple touch gestures.
See below for a demo of SoundMashine in action.
SoundMashine is $.99 in the App Store.
