[chuck-users] WvOut format (Spencer Salazar)

Sat Jun 14 18:15:30 EDT 2014

Ok,

I just tried this on Windoze 8.1 Pro.  Newest installer from
The ChucK/mini download page.  Ran both command line
and miniAudicle.  Audacity, QuickTime player, iTunes, and 
my own sndview (DOSBox based sound/spectrum viewer,
First created in 1988, migrated forward since) all read and
play the created file without complaint.

Only GoldWave gave me a warning that the internal size
didn't match the header, but opened it and played it fine.
