- The git username sounded familiar, it's from the same developer that created bzip3.by sinnet3000

If you have the complete file you can calculate the optimal ones. In a streaming scenario that does not work and you have use something you think is good.
by merbanan - So, it looks like this tries to build a model (or rather, multiple layers of models combined with something called context mixing[0]), potentially analyzing the whole file first? Is it fair to call this a very fancy entropy coder, replacing the last phase of what a traditional audio codec does (the lossless part, after quantization)?
I like the code style, this is pretty nice C. It's refreshing to see human code.
