What Are Multisession CDs?

If you’ve ever wanted to expand medium of compact discs to video, photo, or executable programs, then multisession CDs are the way to go. It’s an excellent way of releasing two formats simultaneously on one disc, and we can take care of the authoring!

What are Multisession CDs?

Multisession CDs, also known as Enhanced CD, contain two different sections. The first is CD-audio, which is the music that plays when you pop the CD into a CD player. This contains the same Red Book audio standards as your typical CD— stereo 16-bit / 44.1kHz audio files.

The second section is a digital folder which can be accessed by reading the CD on a computer. You will see a disc folder that has digital files, such as video, images, or PDFs.

Above is an image of how a multisession CD appears in File Explorer. Enhanced CDs will have a + symbol in the icon. Media players such as VLC or iTunes may open automatically when the disc is inserted based on your computer autoplay settings. To view the data in the folder, right click the icon and click Open.

What can you add to a Multisession CD?

That’s up to you! You can add music videos to your enhanced disc, or an all-access backstage pass video showing the band on the road. Many bands choose to add images or PDFs depicting high-resolution artwork and liner notes. The more computer-savvy artist may even consider programming an interactive executable file.

Are there limitations to Multisession CDs?

A CD holds 700MB of data, and there’s a good chance that a chunk of the disc will be taken up by the audio. If there’s not enough space for every file you’d like to include, you may want to consider compressing larger files like videos or image-heavy PDFs.

Another thing to keep in mind is that you want the experience to be friendly to both Windows and Mac users. For example, Windows users won’t be able to open a DMG, and Mac users won’t be able to open an EXE.
