Is it possible to add tracks on a home-recorded audio-CD, where I already put some tracks on it??? Or do I always have to close the CD to make it readable in a conventional audio-cd reader? Which progs do I hav to use?
Nope, can’t add audio.
Yes, CD is closed after burning.
You could try re-doing a CD-RW, but I’ve never gotten one to play on anything but my computer.
