I want to start converting my CD's (.cda files) to mp3.  What is the best software to do this with?  Is there just freeware I can use or would it be better to use a well known product, and are you aware of what's best quality?

https://en.wikipedia.org/wiki/.cda_file explains format of .cda files which contain no audio.

Since there's no audio, there is no way to convert them.

You'll convert the underlying .wav or whatever audio files your .cda file references.

Just open your .cda file in a text editor, to see the underlying (actual) audio files.

If required, you can always write a PERL or BASH script to read your .cda file(s) then run ffmpeg to convert your audio files from one format to another.

You'll use ffmpeg for the actual conversion, between file formats.

I've never heard this before.  The file extensions are .cda.  Open one of them up...guess what CDA format.

To get back to my original question what file converters are there out there, and what would you recommend.

Post a full copy of your .cda file + someone can provide you an answer.

Or you can just open up your .cda file in a text editor.

Can you recommend a file converter application?

If you are actually working with CD's and not just files, then I use the following tool to rip those to either lossless FLAC or compressed MP3 with good results.  It's an inexpensive paid product, but works well.

If you are starting from actual files, I'd be curious haw large the CDA files are, and where they came from?

The above is a just a ripper.  Never mind.  I'll google it and see what I can come up with.  Thank you for trying.

Well what you are talking about is actually "ripping" a CD.  The CDA file is just a small metadata file that windows uses on the CD to catalog and locate the actual data stream of the audio component.  The audio component itself is not exposed as a file in the Windows file system.  Hence the need for a "ripping" type program that understands the "hidden structure" of the CD and can extract the original digital content and then convert it into a new file format.  The old Windows Media Player used to be able to do this as well as iTunes, but in the end they are all "ripping".

Beyond that I'm not sure what you are trying to do...

This is more what I was looking for.  I didn't want to just copy the files I want to convert the format

That does exactly the same thing as the solution I provided, it rips files from a CD converting to a different format where the audio data is in a single file.  And the free version is limited, if you have a lot to do you end up buying the paid version anyway.

TBH anyone offering "CDA" to "MP3" "conversion tools" is trying to take advantage of customers who don't understand what a .CDA file does.

See https://www.experts-exchange.com/questions/26189216/Convert-MP3-to-CDA.html

The free cd burning tool listed in that thread will convert your music files into .mp3

.CDA files don't contain any audio they (as everyone else is saying) are just a bookmark to the music which is hidden behind them. (In pcm .wav format)
If you are using a Windows environment you can use Windows Media Player to rip "cda" files...

what others explained above is: if you copy a cda file from the CD  to your computer and try to convert the resulting file, you do not get a mp3 file... the cda (i.e. "CDA files don't contain any audio they (as everyone else is saying) are just a bookmark to the music which is hidden behind them. (In pcm .wav format)").

it's not because you have never heard of this that makes in untrue!
