        OS/Version: Mac OS X 10.5

The audio support in WebKit allows you to specify "looping" when an audio clip
is played.  Unfortunately, the looping is not seamless.  There is a sub-second,
but very noticeable amount of silence between when the end of the clip is
reached, and when the start of the clip starts playing again.  Here's a sample
you can run from the Develop/Show Snippet Editor in Safari:

   <audio
     
src="http://media.freesound.org/data/0/sounds/319__Anton__Osc2_Puls_25PW_220.wav"
      autoplay="true"
      loop="true"> 

That sound clip is a simple stable sound which loops fine in Ableton Live
(music product application).  I can set it to loop and it'll play that
horrifying tone for as long as I want with no breaks.  When played with the
<audio> element, a noticeable delay is heard when looping.

That sound clip is available from the following web site:
