This effect, as previously mentioned, is able to increase or decrease the input signal's tonality. This characteristic can be used in many different and interesting ways. For example, you can set up the effect in such a way that the input note is increased by an octave (this modality is sometimes used in electric guitar solos). By acting upon the delay with which the notes are emitted and the increase (decrease) in tonality, different effects can be created:
Image a) shows how it is possible to create an arpeggio effect by producing sound copies that are delayed in time with step-by-step increases in tonality. In b) we see how, leaving the pitch as it is, the pitch shifter acts like a delay. In c) we are shown how by putting delay time to 0 we can create chords by playing one single note.
The following is a sound to which a pitch shifter effect has been applied.
