Audio File Requirements
The content uploader accepts either .WAV or .MP3 files. .WAV files should be saved as 44.1 kHz, 16 bit, stereo files. .MP3 files should be encoded between 128 and 320 kbps with non-variable compression (VBR off). Audio files with other settings will result in order delays. .WAV files are recommended for the best audio quality.
*CD-Text is not currently supported for uploaded content. If you require CD-Text you must mail in your master for production.
Uploading an Audio Album
Make sure you have the "Audio Upload" tab selected and start out by giving the album a name. Click "Add Track" to start adding your audio files, you can select all your files at once at a time by holding down the shift key and selecting the first and last files in the list. Once you have the files added, you can use the up and down arrow buttons to sequence the tracks in the order you want as well as the "Delete" button to remove tracks that you've added. You may additionally change the names of your tracks in the uploader before clicking "Upload Now".
Addition or deletion of a track from an album, re-sequencing tracks, or renaming tracks or albums is not possible once an album has been uploaded. If you change anything, you will need to re-upload the album with those adjustments.
The size of an audio album may not exceed 79 minutes of listening time. Files in an audio album must all be of the same type, they must all be .WAV files or all be .MP3 files.
Uploaded audio albums used in projects will create a (Redbook) standard Audio CD, playable on nearly all Audio CD players as well as computer based media players like iTunes, Windows Media Player, Winamp, etc.
An audio album may include only audio files, data files cannot be included in the album. You must mail in your master for Enhanced CDs (CD-Extra / CD-Plus), do not use the content uploader for your project.
Uploaded content is not altered in any way, the audio quality provided will be the audio quality of your final product. Any static, clicks, pops, skips, etc. in the original files will be faithfully reproduced. By providing us with content, you are responsible for the quality.
*CD-Text is not currently supported for uploaded content. If you require CD-Text you must mail in your master for production.
Previewing Uploaded Tracks
Low-resolution previews are made available for you to quickly listen to your uploaded audio content. Previews are created at 64 kbps and do not reflect the quality of your original uploaded tracks.
Previews are available in the My Content section of your account as well as the "Add Disc Content" step of assembling your project. They may take as long as an hour to generate and not available for listening immediately after uploading. This does not represent an immediate problem with your content.
Displaying Artist and Track Information on Computers / CD Players
There are two different ways this is accomplished.
Gracenote / CDDB: You can submit your CD to an online database of CD artist, album, and track information. Some applications / programs, such as iTunes, will download and display this information upon disc recognition. It is not uncommon for there to be multiple artist / album matches for a CD. The information displayed will be incorrect until it is submitted to Gracenote.
Visit www.gracenote.com for more information.
CD-Text: CD-Text allows capable players to display artist and track information without being connected to the internet. CDs can be authored using the CD-Text options in applications / programs such as Toast or Nero. The content uploader does not currently support CD-Text. If you do require it, you will need to mail in your master, be sure to note on the master that it contains CD-Text.
Gapless Playback (Continuous Mix CDs)
If you are uploading your content, we neither add or remove space between tracks. Any space / silence between tracks is a result of the supplied audio file, even if it's just a microsecond. Gaps may appear between tracks depending on how the files are created, oftentimes when CDs are "ripped" a space may be introduced at the start or end the resulting file. Alternatively, If you wish to add gaps or silence of any specific length between your tracks, you must insert the desired space / silence to the end of the file after the track ends. You cannot use the content uploader to add or remove gaps between tracks. If you are concerned that your audio files are not set up properly, we recommend that you author a master CD, test it thoroughly, and mail in your master.
