its probably not so important to make a fate test for this also
atrac3p uses floats so there could be rounding issues that make this
a bit harder
if you want to try anyway, look at commits which added fate tests for
other decoders.
Also ideally we would like to avoid having to add a wav pcm reference
to the fate samples, so hopefully one of the samples decodes bit
identical between platforms (i can test a few if someone posts a patch
adding a fate test)
