Questions on digital audio would be fine both in the
DVD Projects > Edit Audio & Video forum, or simply the
Digital Life > Computers forum. Both locations will work for audio topics. We'll move topics that are made in the wrong place, using the option that leaves temporary moved links for several days so you'll always know where it went.
On to the question...
If you want to rip an image,
ImgBurn works fine for most CDs. Note that there are some protected discs and atypical compilation discs that don't rip well with
ImgBurn, so you'd want to look at a non-free tool like
CloneCD for those.
I prefer to rip as ISO files when using ImgBurn. By default, sometimes ImgBurn wants to save as a BIN/CUE file set, but I don't really like .bin/.cue files. Just my preference.
If you want to create MP3 files from an audio CD, then you're not looking to rip images. For that task, I use the very old Nero 6. If you have Nero, try it.
Another excellent tool -- and very popular amongst audio purists -- is the freeware tool EAC (Exact Audio Copy).
Generally audio ripping tools make one MP3 file per track. It sounds like maybe you're wanting to merge all tracks into a single MP3 file?
EAC may have that option -- I can't test it right now -- so look in some of the advanced ripping options.
Ripping as WAV files, and then merging the WAVs in a freeware editor like Audacity is another option. Then you can convert the WAV to MP3 with any number of freeware converters. Audacity may have the ability to save as MP3, too -- can't test it right now myself. But it's something to look for.
Hope this helps.
