On the Track Properties tab you will find basic information on the selected file in the Source information area. To open the window, mark an audio file in the compilation screen for Audio CDs and click the Edit > Properties menu. 
The following input areas are available in the Properties area:
Input field
Title (CD Text)

Defines a title which is saved as CD Text. CD players that support CD Text show the title name entered here.
Only Latin characters can be displayed as CD Text. CD Text can only be written in disc-at-once mode.

Input field
Artist (CD Text)

Defines the artist which is saved as CD Text. CD players that support CD Text show the artist’s name entered here.
Only Latin characters can be displayed as CD Text. CD Text can only be written in disc-at-once mode.

Input field
Pause

Defines the length of the pause in seconds or frames between the selected audio file and the next one.

Input field
International Standard Recording Code (ISRC)

Identifies the CD title using a 12-character digital code. The ISRC is entered in the subcode and included silently.
If you do not know the ISRC, you should leave this input field blank.

Check box
Protection

Sets the copy protection bit for the corresponding track on the Audio CD. As most CD recording applications simply ignore this bit, copy protection cannot be ensured. A warning message will be opened in Nero Burning ROM while copying an Audio CD with copy protected tracks.

Check box
Cross fade with previous track

Defines a crossfade between this and the previous audio file. You can specify the length of the crossfade in seconds or in sectors.  

Frame
With an Audio CD, 75 sectors provide one second of played music. One sector consists of up to 98 frames; one frame contains 24 data bytes and 9 control bytes. Similarly, “frame” describes a full screen in television and video technology. Two successive half images result in a full screen within a second due to interlacing.
