CD Extra (also known as Enhanced CD, CD-E, E-CD, and CD Plus) allows you to include on your CD a track of data readable by a computer's CD-ROM drive (but that will be properly ignored by a standard CD player). This lets you include photographs, liner notes, lyrics, webpages, links to websites, and multimedia such as mp4 video, along with your CD's audio tracks. TSM's Basic CD Extra Authoring Package is $120 (additional to the cost of standard DDP or CD-R master discs) and includes: • proper encoding of the master to all Blue Book specifications • creation of an HTML Table Of Contents page that opens the CD’s data contents and any websites you wish to link to • creation of a simple text txt “read me” file containing notes and instructions on how to launch the multimedia content for those browsing the CD’s data contents What we need from you: • text saved as simple text (txt), rich text format (rtf), Microsoft Word doc, or HTML • urls (web addresses) of any websites you wish to link to • any logos or graphics you wish to have appear on the HTML table of contents page • photos and image files saved as jpeg (jpg), tif, gif or png • any other multimedia or application files, such as videos (mp4, webm, mkv, etc.) Additional charges are quoted on a per job basis for encoding or converting multimedia files to proper formats, or for the creation of additonal content. To figure out how many megabytes of space are left over for the data portion of your Enhanced CD, choose whether you wish to keep the disc at up to 74 minutes total (which some pressing plants prefer), or up to the maximum 80 minutes, enter the total time of your audio, and then hit the "Free Space" button - in the calculator below:
