...ing of rice codes.
Agreed, there's too much juggling going on to compete with rice codes, but
maybe it can run at an acceptable speed with a bit of tuning... did you
tell it to write the least significant bits separately (set the parameter
base_2_part=true)? Also altering the algorithm so that low_bits is larger
will produce a speedup (but impact the compression ratio). And there's a
fair scope for optimization.
Overall, the speed (after encoding the least significant bits and
dividing them out) is going to be of the order of the sum of the integers
to be encoded.

Interesting is that for slightly larger low_bits is compression ratio
sometimes better, at least in my case :). Maybe it takes more
iterations to adapt step variable well a...

Hello,
I am the author of the Bonk audio compression program... i've just been
looking at your comparrison table, and i noticed bonk gets marginally
better compression than Flac on some files (actually i was
rather surprised to see bonk on the list at all, it's not exactly high
profile :-) ).
Bonk in lossless mode is a pretty naive implementation of a predictive
coder, so the main
