How does it work?

Two independent and simultaneous transposers can be used with delays and modulations to transpose the pitch of an input sound, while a pitch follower detects the pitch of the input sound and optimizes the transposition.

The transpose, delay, and gain sliders control the transpositions and delays. The periodic modulation controls, to the right in the screen shot above, let you choose the shape of the modulator waveform ('sine' is shown) as well as its frequency, amplitude and phase. If the amplitude of the modulator is low and the frequency is about 5 Hz, the effect will be a vibrato. The random modulation sliders let you add randomness to the modulation. The feedback slider adds reverb, the mono / st slider directs the transposed voices to both or each channel, and the direct slider controls the amplitude of the original input signal. The cross-fade, window, and pitch detector controls affect the functioning of the transposition algorithm.
