Hello!

Is it possible to use the hv.freqshift~ as a pitch shifter maintaining the same ratio for each interval irrespectively of the incoming frequency? For example, use it to transpose a specific interval.
Thanks

no I think you have to get the incoming frequency seperately because freqshifting uses a complex oscillator.
Once you have the incoming frequency you could scale it with multiplication.
btw frequency shifting is different from pitch shifting. In pitch shifting all the harmonics/frequencies are scaled by a certain amount whereas in frequency shifting they are just shifted, keeping the distance between frequencies/harmonics the same.
pitch shifting: f2 = f1*c where c is a multiplier and f1 and f2 are frequencies (e.g c is. 2 for an octave up) vs
frequency shifting: f2 = f1+c where c is a frequency

Thank you for the clarification.
I was testing hv.freqshift with sine waves and couldn't notice the difference but it was evident when used with adc~.
