xTrem is a free tremolo Audio Unit plugin developed by Music Unfolding. Compatible OS(s): macOS.
xTrem is a tremolo unit capable of a range of tremolo shapes; it works as a mono or stereo tremolo. In mono mode, the left channel controls are active. The two channels are fully independent except for the tremolo depth setting, this gives it the capability of producing some interesting panning/tremolo combinations.
