That is why view3dscene can cache by URLs, so multiple AudioClips with 
the same url load their resources only once :) Each one can still have

http://www.web3d.org/x3d/content/examples/Vrml2.0Sourcebook/Chapter24-Sound/Figure24.4FourKeyKeyboard.x3d 
in view3dscene with debug log (you run view3dscene from the terminal 
with --debug-log option) you'll see this:
