NeSi xTrem is an Audio Unit, or AU, for iOS. This application is simply a container for the Audio Unit and also serves as the documentation for the AU. xTrem must be used in some sort of Audio Unit host or DAW application.

NeSi xTrem is a stereo-stereo tremolo effect that uses FM based LFO's and includes VCA and low-pass gate based modulation of the audio signal volume. This provides a unique tremolo signature that is ideal for adding color and movement to instrument tracks.
