29c2fcb677 Use correct value for range 
The current range value causes an underflow
when negated and pushes anything less than zero
to the minimum.

768261e50d Fix some int / int16_t / int32_t confusion 
For now force everything to int16_t, except
for variables used as index

bf8715719a Fix two more int16_t vs. int confusion 
If everything works fine for 16-bit streams,
the current code could be extended to do 24-bit.

be8a0d26db Init s->cdlms[][].recent to order - 1 
Not sure if this is correct. But looks like
it was giving us off-by-one's when used to index
buffers.

e6c66fcf68 Fix some int vs. int16_t confusion 
Size should be determined from bits per sample.
The current code only accepts 16-bit streams.
