Hello,

Can you talk on the phone and have the listener hear the voice previously processed with PD?

@EMR66 i never tried that, but it should not be a problem...
i would try to go from audio out of the computer with a chinch cable to the audio in of the smartphone. perhaps you need a y-cable that splits up áudio in and out for also hearing the person you are talking to (like it is solved with headsets)?

And do you have an idea how to patch it in pd? especially the exit to the phone

other than linux

@EMR66 Something like this....... phone.pd
As you will see in the notes...... the only problem is getting the output from Pd into your phone microphone input without the plug cutting off the phone speaker so that you can no longer hear the other person.
Android and i-phone inputs are different, and whether the plug cuts off the internal microphone will depend on the impedance it sees on its input.
For a house phone or mobile it will be easiest and cheapest to put a small speaker (some earbuds?) on the headphone output from your computer and tape it to the phone microphone...... that is a universal solution too.....
David.

I'm going to try, thanks David
