What makes FLAC so widely used? Because it's asymmetric? Are people satisfied enough by compression ratio or is it price for high decoding speed?

Last time I start to compress my CD rips with even more asymmetric settings:
-l 12 -b 1152 -r 6 -e

Compression ratio is as of -4 preset but decode speed is higher than for -3 and 10% slower than -0. It's of course at cost of lower encoding speed than of -4 preset.

flac was the first (free) lossless codec, I think
A bit before my time (here) but wouldn't Shorten be better suited to hold that accolade? There may be even earlier codecs.

I never understood, what does -A tukey(0.5) -A flattop do?
IIRC recent versions of FLAC (1.1.3 + I think) use -A tukey(0.5) by default in the higher compression settings. Using two -A switches will increase compression ever-so-slightly, but will also drastically reduce encoding speed. I really can't see the point.

depends on what's meant by 'free'. shorten was only free for non-commecial use. ogg squish was also around before flac but not actively developed.

I never had to pay for LPAC and RKAU had also a lossy mode. But in that time lossless files were much too big for my (small) disks.

BTW only -8 when I use FLAC
