stutter~ clicks


    Jan 01 2008 | 2:10 pm
    Dear all,
    just a quick question... I have been looking at the stutter~ object, and although it performs really well, I seem to get lots of clicking and popping over my output signal, even when it is not in operation (stuttering). I have just been using the stutter~ help file but I get the clicks in this patch too.
    When it is not in operation, passing audio through the object works perfectly to start with, but as soon as I change the grain size or playback speed, the clicks appear, most noticeable when the playback speed is very low ( around 0.1). Hope this makes sense...
    Is this a common problem with anyone else?
    Regards

      It sounds like you may be having dsp performance issues. Try adjusting (to a larger size) the signal & i/o vectors, and make sure 'overdrive' and 'scheduler in audio interrupt' are enabled in the 'dsp status' menu. See if that helps.

      Thanks for your repsonce -
      Unfortunately your suggestion has not helped me. I am using the stutter object help file to test but still not working correctly...
      I have changed the adc~ input to be sfplay~, and I'm just playing a wav fil through it. This is then going into the stutter object. Initially, the grain size is set to 100, and the audio passes trough without any problems. Its when I change this grain size (especially a small grain size) that my original signal is getting distorted. This is all when my audio is not stuttering...
      Should the audio entering the stutter object pass through unaltered when the stutter object is not stuttering?
      here is the code I'm using...it would be good to know if it is just my computer being silly or if I'm doing something wrong.
      If you do try the code below, could you try feeding an audio file through, then try changing the grain size, and also try the playback speed, and see if you hear any regular clicking etc when the file is not stuttering.
      Many Thanks....

      I do get clicks when changing the grain and speed settings. I've never used [stutter~] before, so not sure I can be of much help at this point. I'm not sure if it's significant, but when I load your patch I get an error in the Max window: error: 'start: no such object. I also get the same clicking behavior on the [stutter~] help patch, by the way.

      Has anybody got a solution for this?
      How would you create a ramp to smooth between iterations?

      Hi, from what I've read I'm not sure your problem has to do with ramps, might be dsp settings or possibly even weirdness in playing sounds at such a low speed.
      But feel free to apply this "adjustable-hanning-window" i made long ago which I (probably annoyingly) love to go off about constantly to everyone on this forum:

      Thanks for posting this! Solved the clicking problem wonderfully.

      (Wow, from 2008?! I thought I only started forums after max5, but here I shared max4 text... How time flies...)
      This reminds me, there is another share I've been planning for my "sharing is for asswipes" series: standard stutter, and 'zipper' stutter(accelerating/decelerating) made in gen~(with built-in windowing). I will get on preparing that to share in the next couple weeks, thanks for the reminder :)

      sounds like it'll be a popular share, for sure! Get right on it! :)

      @wetterberg Although you asked me to comment this patch a bit more: https://cycling74.com/forums/sharing-is-for-asswipes-anaechowat-a-unique-delay-made-in-gen/
      and then when i did so, you never said 'thank you, asswipe!'... never fear! I merely assumed it was because you were a busy person and not because you are a 'terrible' person >;D So i will continue to attempt delivering to your satisfaction: https://cycling74.com/forums/sharing-is-for-asswipes-fart-noises-in-gen-aka-stutters-d/

      ah, but my gratitude is eternal, ever-present, and deeper than the Mariana Trench!
      (also, I'm a forgetful idiot. So there's that...)
      And I have a habit of becoming overwhelmed in the head whenever the work of others really challenges mah headz. I am trying to get over that. Raja, you're awesome *points finger-guns*.
