EAC: How to set/change FLAC compression ratio

After 8k MP3s I just discovered rational for lossless

I have FLAC setup with EAC as the front-end.

I have command line options:
--best %s -T title="%t" -T artist="%a" -T date="%Y" -T genre="%m" -T album="%g" -T tracknumber="%n" -T libid="CALU"

I ripped/encoded a title: Adouma -Santana  WAV=43.9k  FLAC=31.6k
THat's only a 30% space saver.

What do I change within EAC to achieve higher compression?

TIA
EAC095pb5, LAME3.98, freedb, flac 1.2.1, fb2k 0.9.5

The --best line means FLAC is already giving it the best compression it can. There are a few other codecs that give better compression than FLAC, but at the most only a couple percentage points. Lossless encoders tend to do better on quieter material. Modern dynamically compressed music doesn't tend to compress very well.

I've been wondering the same thing about --best. But, I know this is stupid but just to be 100% clear, no matter what command we use (--best say) it will always be lossless and can always get back the original wav? Correct?

No matter what level of compression you use, a lossless file will always restore to the original wav.  The only thing higher commpression does is on some codecs, it's more intensive (i.e. longer) to decode them.

when I add --best to my command line:

-T "artist=%a" -T "title=%t" -T "album=%g" -T "date=%y" -T "tracknumber=%n" -T "genre=%m" %s

I get an error message;  can't open input file, but the compression seems to go ok.  what's going on?

Try:
-8 -T "artist=%a" -T "title=%t" -T "album=%g" -T "date=%y" -T "tracknumber=%n" -T "genre=%m" %s

-8 is the same as --best

Generally true, but not so for FLAC files. Unless you use an insane custom compression level, compression rate does not affect decode time.
