Caveat: I have no experience with the wave module I just
read the docs....

The docs say the number is the sample size in bytes. So a 4 means you
are writing 4 byte = 32 bit samples. Maybe the original file was using
16 bit?

Based on the documentation you would need a samplesize of 2.
Documentation is really useful. :-)
