I could do, but it wouldn't be nearly as efficient. Sample mixing is one
of those trivial little operations that gets repeated millions of times
in a tight loop, so switching from 32 to 64 bit ints would cause a
significant performance hit. 

I think that by tweaking the shift value I can get it to play samples up
to a minute or two in length, and anything much longer than that is
going to have trouble fitting into memory in any case...
