csGrain has ten core effects; Pitch Shift, Ring Modulation, Chorus, Flanger, Delay, Reverse, High-Pass Filter, Low-Pass Filter, Reverb, and SyncGrain (a real-time granular synthesizer). A Compressor and Limiter are also included for post-processing.
With the addition of Audiobus support you can now transform audio directly from other apps, as well as import audio from iTunes, Dropbox, or AudioCopy to remix in real-time.
Use the SoundCloud player on the right to listen to audio examples of some of csGrain's presets. All of the audio was recorded directly from the application with no further processing and should give you an idea of the variety of sounds that csGrain is capable of producing.
