I have a mess in my brains: what is the difference between freqshift~ (time-domain freq shifter) and fbinshift~ (freq domain freq shifter) and gizmo~ (freq domain pitch shifter)? The two first ones seem to have the same output when applied to sound. Also the concept of time-domain frequency shifter versus frequency domain freq shifter. I would appreciate some background theory of what is going on in the signal. Thanks!
From what i know, a frequency shifter works different than a pitch shifter.
A frequency shifter creates sidebands dictated by a ratio in Hz and does not maintain the harmonic relationship of a sound, a Pitch shifter on the other hand, maintains the harmonic relationship of a sound and just shifts the pitch. http://electronicmusic.wikia.com/wiki/Frequency_shifter
I wish i could explain the theory in detail but that’s all I know.
@ardodot, yes I know the difference between pitch and frequency shifter. but thx for your answer anyway.
my question was about those three ways to make a frequency shifter, the difference was not clear for me. but yes if you want a swiss knive of shifting gizmo is the tool, if you just want something simple freqshift~ is ok and I suppose less expensive than fft.
