Why does Blitzmax fail to load in some wav files?

For the record I had some problems with wav files I was getting out of online sound archives. I use audacity too, and ultimately I found the problem to be one of the PCM variations I was using. (It was something Iphone liked. and I had used on a previous project.) Changed it to 16 bit pcm and haven't had any problems since.
Following up on this thread:
What is the best compression algorithm I could use that BLitzmax supports?
