Nero has an integrated CD player which can play audio files before they are saved so that you can check whether you really want to save them. The player can also play tracks digitally so it can send the audio files direct to the sound card. This means that even if the recorder is not connected to the sound card by a cable the audio files can still be played with the sound card.
Tip: The CD player blocks all other functions in Nero so it is not advisable to let it run in the background. However the Nero Wave Editor program which is part of the Nero package provides you with a full CD player which does not affect your working with Nero. You will find this program when you select:
Start > Programs > Ahead Nero > Nero Wave Editor.
