Or the cricket ? Presumably the Aussie showings are just one long  
silence....

Tim,
Are you happy to fix the wiki ? You seem to have a better grasp of the  
numbers.
Would be nice to incorporate Warpme's unicode fix (from wiki) as well.

Assuming you've fixed the overflow issue, those thresholds look alarmingly  
wide. The threshold is quite a crude instrument. Provided it is detecting  
silences at the appropriate places I've found you're better off tweaking  
the other parameters to achieve the right cuts. Someone has already added  
Aussie presets to the wiki. Have you tried those ?

Lastly, be aware that this mail list uses bottom-posting. People get upset  
if you repeatedly top-post.
