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

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.
