Converting CDA files to mp3’s is a relatively simple process, and is supported by several programs such as WinAmp, Itunes, and others. In WinAmp, open the CDA file in Winamp and select Play. While the song is in the Playlist, right click on it and select the option to Send To: Format Converter from the menu. Choose the MP# Encoder, choose the filename and location to save the new file, then click OK. The program will do the conversion and save your new file.
