The Stereodetune is a software simulation of a harmonizer effect pedal. It records the input signal into a stereo digital delay line of variable length. Each channel of the stereo delay line is read back at a different speed to shift their pitch in opposite directions. The stereo channels are inverted and added to the original signal. It lets you widen the sound in the stereo field. It provides controls to set the amount of pitch shift and delay for both channels, as well as apply or bypass the effect. The Stereodetune is normally used as a send effect.
