[JAVA3D] Sound + Doppler effect

[Alex Terrazas]

Hi!

Has anyone successfully used the Doppler effect with a
Sound Node object?  Using a moving pure tone, I was
not able to generate any noticable difference.  I tried a
variety of settings with


      AuralAttributes aa = new AuralAttributes();
      aa.setFrequencyScaleFactor();
      aa.setVelocityScaleFactor();

None produced anything noticable.

Thanks--

Alex
