Analog would be like you used Sound Recoder to record sounds coming from your line-in or microphone port.
Digital is if you use a ripping program like CDex, EAC or RealJukebox.
Also CD audio is 44.1Khz
Also 8s - 9s aren't bad ? No ones bitching at those scores. Some people use the audio score to say how well the audio/video matched. Though I doubt that's the case.
Someone doing basic ripping is not getting 100% quality out of their files. If you really cared you'd like use EAC and make sure you got the least amount of errors as possible(even maybe buying a new CD if there were too many). Then reading up on using LAME and getting the best MP3 encode possible.
So actually I believe with lame there is a preset that works best and it encodes your mp3 @ 192Kbits.
So you know, a 8 or a 9, means it's good. 10 would be if you went into detail on how you got the audio and specifically put "I MADE THE AUDIO AS GOOD AS FREAKIN' POSSIBLE".
