List input and output audio devices in Applet
- by Jhonny Everson
I am running a signed applet that needs to provide the ability for the user to select the input and output audio devices ( similar to what skype provides).
I borrowed the following code from other thread:
import javax.sound.sampled.*;
public class SoundAudit {
public static void main(String[] args) { try {
System.out.println("OS: "+System.getProperty("os.name")+" "+
System.getProperty("os.version")+"/"+
System.getProperty("os.arch")+"\nJava: "+
System.getProperty("java.version")+" ("+
System.getProperty("java.vendor")+")\n");
for (Mixer.Info thisMixerInfo : AudioSystem.getMixerInfo()) {
System.out.println("Mixer: "+thisMixerInfo.getDescription()+
" ["+thisMixerInfo.getName()+"]");
Mixer thisMixer = AudioSystem.getMixer(thisMixerInfo);
for (Line.Info thisLineInfo:thisMixer.getSourceLineInfo()) {
if (thisLineInfo.getLineClass().getName().equals(
"javax.sound.sampled.Port")) {
Line thisLine = thisMixer.getLine(thisLineInfo);
thisLine.open();
System.out.println(" Source Port: "
+thisLineInfo.toString());
for (Control thisControl : thisLine.getControls()) {
System.out.println(AnalyzeControl(thisControl));}
thisLine.close();}}
for (Line.Info thisLineInfo:thisMixer.getTargetLineInfo()) {
if (thisLineInfo.getLineClass().getName().equals(
"javax.sound.sampled.Port")) {
Line thisLine = thisMixer.getLine(thisLineInfo);
thisLine.open();
System.out.println(" Target Port: "
+thisLineInfo.toString());
for (Control thisControl : thisLine.getControls()) {
System.out.println(AnalyzeControl(thisControl));}
thisLine.close();}}}
} catch (Exception e) {e.printStackTrace();}}
public static String AnalyzeControl(Control thisControl) {
String type = thisControl.getType().toString();
if (thisControl instanceof BooleanControl) {
return " Control: "+type+" (boolean)"; }
if (thisControl instanceof CompoundControl) {
System.out.println(" Control: "+type+
" (compound - values below)");
String toReturn = "";
for (Control children:
((CompoundControl)thisControl).getMemberControls()) {
toReturn+=" "+AnalyzeControl(children)+"\n";}
return toReturn.substring(0, toReturn.length()-1);}
if (thisControl instanceof EnumControl) {
return " Control:"+type+" (enum: "+thisControl.toString()+")";}
if (thisControl instanceof FloatControl) {
return " Control: "+type+" (float: from "+
((FloatControl) thisControl).getMinimum()+" to "+
((FloatControl) thisControl).getMaximum()+")";}
return " Control: unknown type";}
}
But what I get:
Mixer: Software mixer and synthesizer [Java Sound Audio Engine]
Mixer: No details available [Microphone (Pink Front)]
I was expecting the get the real list of my devices (My preferences panels shows 3 output devices and 1 Microphone). I am running on Mac OS X 10.6.7.
Is there other way to get that info from Java?
