Hi,

I would like to make an octave converter directly from adc~ to dac~. So I need to convert input frequency(f1)
f1/2 = 1 octave lower,
f1/4 = 2 octave lower.
f1*2 = 1 octave higher.
etc.
How do you that directly from adc~

@Butahuruf So you want to transpose input one or two octaves down and output it? The easy vanilla way to do this is with an array, but that would make the playback slower. Maybe [soundtouch~], an external from kaatja? http://katjaas.nl/pitchshift/soundtouch~.html

soundtouch~

I prefer using Vanilla and it should have no delay (so is there a way using array?)

@Butahuruf What kind of input will you be giving it?

From adc~

@Butahuruf Try this......... G09 pitchshift-mod2.pd
It's a mod of one of the pd examples in pd/doc.

@whale-av Thx David but it has a delay not a real time. It seems also very complex

@Butahuruf Try reducing the window size (msecs) in the patch....... and also reduce the Delay (msecs) in Pd audio settings as low as it will go without distortion.
David.

@whale-av I've found doc/3.audio.examples/G06.octave.doubler I don't know how to use it in real-time. can you have a look?

By using sigmund~ I can track the incoming frequency and amplitude.
Ho can I convert the frequency to dac?

adc-track.pd

@Butahuruf This is just an aside, but that pitchshift demo G09 can be found as an abstraction in the GuitarExtended patch "TheHexxciter". It's a detuned delay effect.

@gmoon thx I will have a look
