Enhanced CD, also known as CD Extra and CD Plus, is a certification mark of the Recording Industry Association of America for various technologies that combine audio and computer data for use in both compact disc and CD-ROM players.

The primary data formats for Enhanced CD disks are mixed mode (Yellow Book/Red Book), CD-i, hidden track, and multisession (Blue Book).

Problems

Sometimes computer CD ripping programs (particularly cdparanoia) have problems ripping some enhanced CDs, especially those which have the data after the audio section. These CDs have the data 11400 sectors (2m32s) after the audio, but some CD rippers may try to rip this blank section with the last track; the end result is that the ripper stalls during the last track, or simply errors out.
