Auto Feedback?


    May 23 2007 | 2:20 pm
    Hi, does anyone know how I would go about making an auto-feedback system similar to the 'feedback network' Pluggo.
    It would need to turn down a gain control slightly once a threshold level was reached, wait a set time, then gradually increase the gain again.
    I imagine one could use the avg~ object to keep an eye on the level but I'm not quite sure about the rest.
    Helpful thoughts much appreciated.
    Thanks
    Will

      Hi Will,
      Check out the thresh~ object, for starters.

      Sounds like a compressor with a negative knee. Lots of ways to build
      this; here's a simple one. I've found that omx.comp~ is also effective
      for matrix style feedbacks.

      a simple feedback loop would be this:
      make a tapping delay with feedback, put the feedback
      value on 0.999998, then put a limiter in the feedback path.
