Buttercup Bitcrush is a general purpose bit-crusher, sample-rate reduction & noise effect.
Built upon the tenet of simplicity, the flora project presents great sounding, lightweight audio effects using Inter-App Audio and Audiobus technologies to allow you to get the sound you want, without sacrificing processing power.
More information about the flora project can be found at http://timothy-j.com/flora
NB: Buttercup Bitcrush requires either Audiobus or Inter-App Audio capable applications in order to operate. See http://audiob.us for more information.
