class FreqShift(PyoObject):
"""
Frequency shifting using single sideband amplitude modulation.
Shifting frequencies means that the input signal can be detuned,
where the harmonic components of the signal are shifted out of
harmonic alignment with each other, e.g. a signal with harmonics at
100, 200, 300, 400 and 500 Hz, shifted up by 50 Hz, will have harmonics
at 150, 250, 350, 450, and 550 Hz.
Parent class : PyoObject
Parameters:
input : PyoObject
Input signal to process.
shift : float or PyoObject, optional
Amount of shifting in Hertz. Defaults to 100.
Methods:
setInput(x, fadetime) : Replace the `input` attribute.
setShift(x) : Replace the `shift` attribute.
Attributes:
input : PyoObject. Input signal to process.
shift : float or PyoObject. Amount of shifting in Hertz.
Examples:
>>> s = Server().boot()
>>> s.start()
>>> a = SineLoop(freq=300, feedback=.1, mul=.3)
>>> lf1 = Sine(freq=.04, mul=10)
>>> lf2 = Sine(freq=.05, mul=10)
>>> b = FreqShift(a, shift=lf1, mul=.5).out()
>>> c = FreqShift(a, shift=lf2, mul=.5).out(1)
