I see Inertia beat me to the punch. That isn't surprising. He often does.
Anyway, to add just a little bit to Inertia's comments, the reason CD recordings are always made at 16 bits is because the Red Book standard that defines the CD-DA (CD Digital Audio) format requires 16-bit, 44.1 kHz PCM encoding of audio.
If you want to burn CDs with higher resolution, you will have to burn your files as data files on an ISO-9660 data CD in whatever higher resolution format you are using to capture the audio. Then you will probably have to play them back on your computer with a player that is compatible with that higher resolution format. There are some stand-alone devices that will play mp3 files on a data CD, but I don't know about stand-alone players that will play high-resolution formats. By the way, what format are you using?
By the way, don't confuse standard CD-DA discs with the newer Super Audio CD discs. These are a completely different format, and existing burners can not burn Super Audio CDs.
