    it seems that RAR wins this test due to good mix of bmp, wav, text and binary compressors, while SBC omits bmp compressor but has very good one for wavs. in uclc test it provides results very close to wavpack ones - does this mean that it uses exactly the same code?

    Not necessarily, but it means it uses a VERY specific algorithm for wav data.

    i understand, but their results are just too close we should look to another tests to decide

    ps: my english is just very poor

    btw, both rar and sbc features text preprocessing and data segmentation among other tricks. i thought that rar uses raw ppmd algorithm, but my last experiments showed that rar -mc8:48t+ compress much better than ppmd -o8 -m48. it is interesting to mention that rar may even implement decompression for text preprocessing tricks via its VM

    It'll be great when TAK's SDK (or possibly source code) will be released , it has quite impressive wav compression power/(de)compression time ratio. See here

    it's definitely better but only about 1-2% for same speed
