Frequency domain frequency shifter for pfft~ The fbinshift~ object implements a frequency-domain frequency shifter that can be used inside a patch loaded by a pfft~ object. Cycling '74 MSP MSP FFT real/x input TEXT_HERE imaginary/y input TEXT_HERE Amount of Frequency Shift (Hz) TEXT_HERE bin-shifted real/x output TEXT_HERE bin-shifted imaginary/y output TEXT_HERE Frequency shift A numerical argument will be used as the frequency shift in Hertz. The default is zero. Frequency shift Integer inputs are converted to floating-point values and used as the frequency shift in Hertz. The default is zero. Set amount of frequency shift In rightmost inlet: a float in the right inlet will be used as a frequency amount in Hertz by which the complex (real + imaginary) input signal will be shifted. Function depends on inlet In left inlet: The signal present at the left inlet is the real part of a frequency-domain signal coming from a fftin~ object inside a pfft~.

In middle inlet: The signal input to the middle inlet is the imaginary part of a frequency-domain signal coming from a fftin~ object inside a pfft~. Both real and imaginary inputs must be connected for the fbinshift~ to work. The fbinshift~ object works by shifting the frequency bins of an FFT'd signal (hence its name - a shortened form of "frequency-bin shifter"). All the frequencies of the complex input signal are shifted by the Hertz value speified. Positive Hertz values shift upward, whereas negative values shift downward. The fbinshift~ object must be used inside a pfft~; outside a pfft~ it does nothing. The output is the frequency shifted complex signal. The left outlet is the real component, and the right outlet is the imaginary component. These may be connected to the real and imaginary inputs of a fftout~ object inside a pfft~.
