I'm working with the Java Sound API, and it turns out if I want to adjust recording volumes I need to model the hardware that the OS exposes to Java. Turns out there's a lot of variety in what's presented.
Because of this I'm humbly asking that anyone able to help me run the following on their computer and post back the results so that I can get an idea of what's out there.
A thanks in advance to anyone that can assist :-)
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";}
}
All the application does is print out a line about the OS, a line about the JVM, and a few lines about the hardware found that may pertain to recording hardware. For example on my PC at work I get the following:

As Uri noted, the Java Sound API definitely does not produce any interesting results on Mac OS X:
OS: Darwin 9.6.0/i386
Java: 1.6.0_03-p3 (Sun Microsystems Inc.)
Mixer: software mixer and synthesizer [Java Sound Audio Engine]
Also, I should note that I'm using soylatte-1.0.3 rather than the rather elderly JDK distributed with Apple's developer tools.
