If you know that your data is 8 bit mono, it will be

UNSIGNED bytes, not signed :-)

If it were 16 bit stereo it would be stored as pairs of
signed shorts.


Surely the values go +/- zero? 

No. 8 bit PCM is unsigned, with 127 the 'zero' level.

So FF == -1 and so on.  And if cast to a
larger integer value the sign bit should be extended?
