In the Winamp features it doesn't say anything about converting only that it lists 55 different formats it supports. In searches I've found that you can convert Winamp files to MP3.
I'll take that as a no.
No, not ripped with a cd player. Just 15-20 files on my pc that I can't upload to Audacity because they're WMA.
I wasn't talking about using Winamp to convert. I was talking about using it to rip.
You said your own files. I assumed you were talking about files that were yours... not files you got from someone else or from the internet. If you created them, then you made them in WMA. If they came from somewhere else, then I understand you wanting a converter.
I highly recommend Blaze Media Pro, as I use it all the time for many things. It converts audio and video files, allows you to edit videos, rip, burn, make cd images, etc.
You have to pay for it, but it has a 15 day free trial if you just want to use it to convert the files and then discard it.
Make sure when you convert files of any type to test them after converting BEFORE you delete the originals. Sometimes things screw up and you need to convert again, or sometimes the converter does a poor job. Converting anything usually makes whatever it is lose quality, so expect that. It may or may not be noticeable.
