thanks @lacuna I tried your solution but [delread~] doesn't accepts audio signal, right?
How can I try to upsample the delayline?

@whale-av thanks a lot! I tried the [lop~] but as you said I still hear the clicks, so I will try the crossfade. I'd really like to re-create the stompbox delay/echo effect: send a short sound and change the delay time fast, with feedback

Hello! I'm new here and I'm a Pure Data beginner. I'm stuck with an issue that I can't resolve, maybe someone could help me! I'd like to control a Stereo Delay effecting an audio file in real time with knobs (ctlin 34) but when I change the amount of Time Delay I hear some clicks/steps. I tried somehow to use a (line) object but I failed...

Thanks a lot, Leila.
