Newbie Question About Ripping to Wave

I am new to dbpoweramp and I can not figure one thing out and would love for someone to explain this to me.
I am ripping my cds to wave for archiving. I have my encoder set to uncompressed. After it is done ripping and I go in and look at
the id3 tags there is a tag called Encoder Settings beside this it has: -compression="PCM" -wavemp3="-b 320"
What does this mean? This has me concerned that it is not ripping correctly as a wave file.

It just saves all the options on the options page, PCM is uncompressed.
