Hi! Could someone give some advice on how to make a delay based vibrato????

I'm quite new to pd and I've been having some problems

Thanks

If you are interested in modulating the pitch of an external audio source, 3.audio.examples/G09.pitchshift.pd in the docs is an example of dealy based pitch shift. you could try modulating the transposition with an LFO to get a vibrato? I bet that Obi or someone else could explain how it could be done with amplitude modulation perhaps?

Use a vari delay, something like this

signal in

[delwrite~ adelay 500]

[osc~ 3]
|
[*~ 10]
|
[+~ 250]
|
[vd~ adelay]
|
[dac~]

Thanks very much for your help!!!
