To give a longer explaination....

The spec's for WAV's sitting n my hard drive says the 4 bytes at
offset 16 of the WAV file the fmt subchunk holds the length 
of the fmt subchunk.

Its supposed to be 16 for files that are pure PCM,but the spec allows
for extra bits of data at offset 36 before the data subchunck no matter
what the format.

The true test for the data being PCM is the two bytes at offset 20
being equal to 1.
