Currently, I'm ripping my entire CD collection and compressing into FLACs. I'm interested in making the FLACs as small as possible and have no concern whatsoever for encoding time.

To achieve this, I'm currently using -V -p -l 12 -b 4096 -m -e -r 8.
(Those who use FLAC regularly will note these settings are even stronger than -8. I tried using -r 16 which the documentation states is supported, but anything over -r 8 caused an error in my tests.)


My question is: what settings, if any, would allow for even better compression?

Additional settings "-A tukey(0.5) -A flattop" should bring a bit more compression gain.

Thanks for the suggestion. Not knowing anything about the different -A options, I've left it at default in the past. I don't suppose you're aware of a website that discusses the different algorithms in depth?
