A .cda is a CD music file. You can't use it in Premiere Elements.
If you put the CD in your computer's CD drive, you can use Windows Media Player or iTunes to "rip" this file. This saves it as an MP3 -- but even better if you can convert it or save it as a WAV file, which is the ideal audio format for Premiere Elements.
Once you've ripped the file as an MP3, you can easily convert it to a WAV file using the free program Audacity.
Thanks, Steve. I had itunes downloaded but never use it. I used itunes to convert to .m4a and used PE7 to convert to mp4, which I downloaded onto my Blackberry. I needed to listen to a training cd while a drive across town.
For future reference, you could use iTunes to just convert it to an MP3, and do it in one step!
Yea, I thought that's what it would do automatically. And since I was short on time, I went with PE7 because that's what I know. Next time I'll figure out how to use itunes to do it all at once.
Honestly troubleshooting this stuff is tantamount to taking a college level course. The only thing that makes it bearable is knowing I can get help from you gurus in the forum
