Radio bad signal effect?


    May 14 2011 | 2:58 pm
    Hello
    I would like to create a noise and distortion like bad signal from the radio. I will connect itunes live radio streaming.
    I am testing jittery static noise, but it is too clean still. Because it is live audio streaming, I am trying to trigger a Filtergraph~
    Any idea to make this distorting live signal to be triggered more sofisticate way?
    p.s what freq and filtered noise is more similar with actual radio's static sound?
    Thanks

      This is something I've pondered over before but using [groove~] instead of an audio input source. This patch isn't technically correct, but is capable of achieving radio-interference style results.

      A convolution sounds good. maybe I should mix some other variables for more subtle and condensed static distortion... Thank You.

      It sounded like fun so I had a go. I used the hilbert~ transform for some nice ringmod, a bit of rand~ modulated with the inputs volume, add a few random clicks and a little AM modulation for ground hum kind of sound and generally messing it up. Probably overkill but it sounds like poorly tuned radio to me.

      I couldn't resist too...

      wow distortion sounds very cool,
      it seems like a real radio static sounds more like a wind-swirly sound? something like

      it does sounds more spatial whirlwind of lower frequency.. maybe because of radio case,
      maybe should add some resonance and electronic scrachy sound..

      If you really think so, listen to this radio. It's built with maxmsp.

      Anyway, I agree.

      So I had a listen to the YouTube clip and I had another go. I think it's closer If I spent more time at it I could get it. There are a few presets but they are all with no music from sfplay~ just really about the noise.

      Sounds awsome. really love the hiss
