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.

I don't get this, EAC for me always rips the CD to a WAV then pauses while FLAC encodes. This is annoying because I used to use AudioGrabber which encoded the MP3 while ripping, instead of just having the CPU practically idle then the CD drive idle and so on. Anyway it means the speed of the FLAC encode stage is relevent, otherwise obviously it only really needs to be as fast as the rip in practical terms.

You can make EAC encode in the background while ripping if you go to EAC options, under tools, and check "On extraction, start external processors queued in the background".

No way to pipe it straight to the encoder while it rips, then?
Still a lag and wasted time as it encodes the last track, if I understand this right.

Are you talking about "on the fly" encoding (like what CDex does)?
