[Speex-dev] fir_mem_up filter question

In the fir_mem_up filter, the inner loop does a mac on the y0, y1, y2, 
y3 variables.  What is the range of values of those variables?  I would 
like to move the SHR 1 outside the loop after the mac has been done.  
Will this result in a 32 bit overflow of the y0, y2, y2 and y3 variables?
