Hi, I am new to processing and trying to do simple(averaged?) wave forms from Minim MonitorInput. The waveform I keep having has complex spectrum of waveform but I am trying to simplify the points of waveforms. Or how can I change it to the linear averages? which will produce averaged data of input sound?

Thanks.

/** * This sketch demonstrates how to monitor the currently active audio input * of the computer using an AudioInput. What you will actually * be monitoring depends on the current settings of the machine the sketch is running on. * Typically, you will be monitoring the built-in microphone, but if running on a desktop * it's feasible that the user may have the actual audio output of the computer * as the active audio input, or something else entirely. *

GoToLoop,

Thank you for reply but it is a bit hard to understand what you are trying to say with the link. Would you please explain little bit more detaily?

Thanks.

He's recommending you reformat your post so it could be more clearly understood.

if (typing code){
place it in a code block = cntl+'O';
}

I'm trying to do the same thing. My concern is that I'm trowing out valuable information. To get an average start a variable at 0, incrementally at it when you go through each for-loop, then divided by the amount of loops. I did the same thing but it doesn't look less crazy.

I'm struggling to parse the high and lows, and frequency. I can imagine how to do it programmatically, but it feels like overkill.

 portcount=0;
  lave = 0;
  rave = 0;
  for(int i = 0; i < in.bufferSize() - 1; i++)`
      {
        line( i, 50 + in.left.get(i)*50, i+1, 50 + in.left.get(i+1)*50 );
        line( i, 150 + in.right.get(i)*50, i+1, 150 + in.right.get(i+1)*50 );
        //line(i, 0, i, 100);
        lave = lave + (1000 * in.left.get(i));
        rave = rave + (1000 * in.left.get(i));
        portcount++;
      }

    println("left ave: " + lave/portcount);
    println("right ave: " + rave/portcount);

Have you looked back at your first message? It is a mess. Do you expect us to read it?
Have you followed the link and read the topic? Is there anything unclear in it? (I wrote it, so I am interested for feedback.)
