Hi @Aryszin,

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

> **[AudioSystem (Java SE 19 & JDK 19)](https://docs.oracle.com/en/java/javase/19/docs/api/java.desktop/javax/sound/sampled/AudioSystem.html)**
>
> declaration: module: java.desktop, package: javax.sound.sampled, class: AudioSystem

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…

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();

      Control[] ctrls = l.getControls();
      if (ctrls.length > 0) {
        for (Control ctrl : ctrls) {
          handleControl(ctrl, 3);
        }
      } else {
        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 …

Hi @jafal,

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