I record many public talks with the NX recorder which sound great but I need to be able to share these recordings with friends who do not have a computer or a CD player that plays mp3, is ther a free or cheap program that can convert wav or mp3 to cd (cda) format.
Almost all the software provide with the CD burners can do that (WinOnCD, Nero, Roxio Easy CD,...).
Some, because they are light version, won't do it from MP3 but sure they will from WAV...
Check for something like "Create an Audio CD" in the software provided with your burner...
Well yes, you need a burner though!
