Tracks Have Different Audio Levels When You Make a Compilation Audio CD-ROM with Windows Media Player

When you play a compilation audio CD-ROM that you made with Windows Media Player, the audio levels from track to track may not be consistent. For example, some songs or audio tracks may be very loud, and others may be noticeably more quiet.

This behavior can occur because audio CD-ROMs are recorded at differing audio levels, so the songs or tracks on a single audio CD-ROM may not have been recorded at the same audio level as another audio CD-ROM. Because of this, a compilation of songs or tracks from different audio CD-ROMs do not (typically) have matching audio levels. Audio normalization is the process of adjusting the audio levels from differing sources for consistency, but Windows Media Player does not include this functionality.

To work around this behavior, obtain and install a third-party audio CD-ROM creation tool that provides audio normalization.

This behavior is by design.
