How can I convert an mp4 file to cda?
You can't convert an MP4 file to a CDA file because a CDA file format belongs to Audio CDs. You can burn your files to an Audio CD and then copy the CDA files to your computer but you will need to have the CD inserted at all times when you want to play it.
Burning Audio CD can be accomplished with Nero Multimedia Suite, Ashampoo Burning Studio.
