Spreader widens the stereo spectrum of a signal by periodically shifting the frequency range of the original signal, thus changing the perceived width of the signal. You can also use Spreader to specify the delay between channels in samples, which adds to the perceived width and channel separation of a stereo input signal.
Spreader parameters
Intensity slider and field: Determine the modulation amount.
Speed knob and field: Set the speed of the built-in LFO.
Channel Delay slider and field: Set the delay time in samples.
Mix slider and field: Determine the balance between the effect and input signals.
