Wave Export for CD

I was trying to export a wave file for a CD using my matrox Axio LE by going file export audio.
There were a couple of different codecs that I could use each of which I had never heard of before like ccitt u-law or ccitt a-law. What are these for? Uncompressed waveform worked but the file size is big of course but I could burn it to a cd. A couple of the other ones would only burn a mono file. I'm thinking that uncompressed waveform at 16bit 44.1 would work best for a wave file that could be burnt to a cd and played in a standard cd player. Can anyone confirm this?
I have not tried using any of the matrox media encoder settings and just unchecking the video box yet.

Thank you!

Thank you, that is what I assumed. Turns out the Citt U-law and A-law are mobile phone telecommunications audio standard encoding formats.

Thanks for the help.
