[Flac-dev] Not compressing 24 bit very well

[Gordon Gidluck]

Hi Josh,
I am noticing a problem in my application also which does realtime encoding on pocket pc. 

Most 24-bit music content does not compress well. But I have noticed that rectangular waves that I have encoded have compressed fairly well, so it seems to depend upon the predictibility of the content. 

I would also be very interested in a fix for this.

yes, I think it's a problem with the rice coder but I will not be
able to get to this until after the next release.
