i've read most of the cue related theads. I know the basic knowledge. But my question is: I can't use EAC to burn my cdr(it must be a compatible problem between EAC and my drive). So if i extract multiple wav files and now need a cue file to burn with nero, what should i do?

first, i select "Action->Detect gaps";
second, "Action->Appand gaps to next track"(this option was gray if i didn't take the first step);
finally, through "Action->Create CUE sheet->Multiple WAV files with corrected gaps", i got a cue file.

Now i can use this file in nero, but am i right?

If you burn this CUE sheet in Nero you'll have a perfect CD copy (even more perfect than without a CUE). Note: Nero will add 2 second 'pauses' between tracks, be sure to set them to zero (since they are already present in your WAVs), before the first track leave the 2 seconds (Nero would protest anyway).

To summarize: your idea is allright, but only for immediate burning: playing the extracted files on computer will sound awful (tracks start with an annoying silence).

If you want to play them from pc as well, have a look at Case's new idea: here
