Anyone know .wav data points endian format?

Hello, im reading a .wav file and its 16bit mono so my file would go:

....|d|a|t|a|0|0|5|9|-12|33|......

where the first point is |-12|33|
so since it is 16bit does anyone know how to extract the number |-12|33| would represent? I'v tried both endian formats but when ever I get a number and divide it by 2 I keep geting static instead of a scaling.

Any ideas?

For example I have tried |-12|33| = 62497 and also tried |-12|33| = 8692
So ill half this number and write it back but i wont be half the volume it ends up just being static.
How are points in 16bit wav files suppose to be read?
