Can i get the microphone output volume, only the volume without a library? Arys

Hi @Aryszin,

You can use the java audio (Mixer Controls) if you not want to use any further library:

Hi @Aryszin,

Actually that’s not really a processing topic, but I don’t want to be too picky.
Below you find a code that should print out all available mixers for your system and their corresponding controls for it and the possible values the control can have.
(you are looking for s.th … like Master Gain/Float)
For detailed information about the meaning of the possible values look at the AudioSystem reference above.

Hope that helps…

Cheers

import javax.sound.sampled.*;

void setup() {
  getSurface().setVisible(false);
  for (Mixer.Info mi : AudioSystem.getMixerInfo()) {
    println("_".repeat(80));
    println("> [Mixer]: " + mi);
    Mixer mixer = AudioSystem.getMixer(mi);
    Line.Info[] srclineInfo = mixer.getSourceLineInfo();
    if (srclineInfo.length > 0) {
      for (Line.Info li : srclineInfo) {
        handleLine(mixer, li, "SourceLine");
      }

    Line.Info[] tgtlineInfo = mixer.getTargetLineInfo();
    if (tgtlineInfo.length > 0) {

      }
    } else {
      println(">> [TargetLine]: No TargetLine(s) provided");
    }
  }
  exit();
}

void handleLine(Mixer mixer, Line.Info lineInfo, String addonInfo) {
  try {
    println(">> ["+addonInfo+"]: " + lineInfo);
    Line l = mixer.getLine(lineInfo);
    try {
      l.open();
      Control[] ctrls = l.getControls();
      if (ctrls.length > 0) {
        for (Control ctrl : ctrls) {
          handleControl(ctrl, 3);
        }
      } else {
        println(">> ["+addonInfo+"]: No Controls(s) provided");
      }
      l.close();
    }
    catch(Exception e) {
      println(">> ["+addonInfo+"]: No Controls(s) provided");
    }
  }
  catch(Exception e) {
    println(">> ["+addonInfo+"]: no acces to Line:" + e);
  }
}

void handleControl(Control c, int d) {
  String prefix = ">".repeat(d);
  if (c instanceof BooleanControl) {
    BooleanControl b = (BooleanControl)c;
    println(prefix + " ["+b.getType()+"/Boolean]: " + b);
  } else if (c instanceof EnumControl) {
    EnumControl e = (EnumControl)c;
    println(prefix + " ["+e.getType()+"/Enum]: " + e);
  } else if (c instanceof FloatControl) {
    FloatControl f = (FloatControl)c;
    println(prefix + " ["+f.getType()+"/Float]: " + f);
  } else if (c instanceof CompoundControl) {
    CompoundControl cc = (CompoundControl)c;
    println(prefix + " ["+cc.getType()+"/Compound]: " + cc);
    for (Control ctrl : cc.getMemberControls()) {
      handleControl(ctrl, 4);
    }
  } else
    println(prefix + " [UnknownControl]: " + c);
}

Should print out s.th like the below …

@mnse great work

Hi

Can you point or provide same but for microphone frequency reading ??

Thanks in advance

mnse · March 12, 2023, 2:06pm

Hi @jafal,

don’t want to work out but you can check here … (FFT you need to apply for yourself)

Cheers
