George,

This has been a source of problems the past few versions as we have refactored WvOut to optimize real-time performance. That being said I can't reproduce this bug on Windows XP with chuck 1.3.3.0 or 1.3.4.0. I can't test on Windows 7 at the moment, but I may be able to try that a bit later. 

A few ideas-

- Try an absolute path for the file path, or use me.dir():

me.dir() + "/blerg.wav" => string file;

There might be some strange file permissions issues happening if the destination file isn't in a directory chuck can write to. 

- Try updating to the latest version of chuck/mini (1.3.4.0). 

- Do you get the same results in the command line version of chuck as in miniAudicle?

Hello George,

Your example seems to work fine for me on Windows XP

$ chuck --version
chuck version: 1.3.4.0 (chimera)
   microsoft win32 : 32-bit
   http://chuck.cs.princeton.edu/
   http://chuck.stanford.edu/

$ cat blerg.ck

SinOsc s => Gain g => dac;
s.freq(400);
g.gain(0.5);
g => WvOut w => blackhole;
"blerg.wav" => string file;
w.wavFilename(file);
1::second => now;
w.closeFile(file); // what is the function of the argument here? can
WvOut record multiple buffers at once?

$ chuck blerg.ck

blerg.wav opens fine in VLC, Audacity, and Reaper.
