I need to make a audio cd that will play on my car cd player. The only file format that will work is cda. All my files on my pc are MP3. So is there a file converter program that will do this. Also My old stereo system plays the regular cd's that you buy from the store, they are cda format, but it will not play the cda cd that I created a while back from my pc. I cannot find a mp3 to cda converting program.

there's really no such thing as converting mp3 to cda. a "cda" file isn't really a file, but just a representation of the track on the audio cd. what you want is converting mp3 to wav (or wave), which should be easy to find. pretty much all modern cd authoring programs (such as nero) will allow you to directly drag and drop mp3s into the audio cd layout and will convert on the fly to cd audio while burning.

If you don't have Nero then I'd recommend Burrrn (www.burrrn.net) as an excellent Audio CD burner. In fact even with Nero I'd still use burrrn.

You just add the mp3 files & it'll convert as part of the burn process.

Bear in mind that some car stereo systems will not play CD-R. The manual might help there. However, if you use quality media ( I'd recommend Verbatim Pastels & Super AZO) with either a CD writer or LG/Benq DVD writer then you should have success. I've said LG/Benq as these work fo rme , whereas my older NEC 1100 & 2500 wouldn't do it.

I've found that media quality is more important than burn speed but many would suggest burning at no more than 24 speed.

I recomend you use Musicmatch Jukebox http://www.musicmatch.com/ There is a free version that does everything you want
