Glossary

The following table contains a list of terms defined specifically for RealJukebox Plus. While some of these concepts may have broader meanings and implications, the definitions in this glossary relate directly to your use of RealJukebox Plus rather than the world or Internet at large.

A

album: This term refers to your CD as a collection of music. "Album" is a colloquial term dating back to 78 RPM records, which contained only one song on each side. These records were often sold in books or "albums" comprising multiple slip-covers, each holding a single record.
analog: This is the original sound wave, which can be converted into digital data or can be recreated from a previously stored data file. CDs store information as digital data and CD players convert the signal back from digital into analog form so you can hear it.
analog extraction (recording): If your CD ROM does not support digital audio extraction, analog recording is used. This method records the actual sound output of your CD as it is routed through your soundcard.
artist: The band, composer, singer, etc. who recorded your CD.
ask-tell-help: RealNetworks policy of "Fair Practices & Conventions for Handling File Formats in the Era of the Internet." RealJukebox always asks before making itself the default player for music file types. For more information on this policy, click here.

B

bitrate: The amount of digital information being stored per second of audio. In general, a higher bitrate means better sound quality with a larger file size.
"blocks": Unit of measurement describing the amount of data RealJukebox reads from your CD. One "block" equals 2 "frames".
browser: Short for Internet browser (for example, Netscape Navigator or Internet Explorer).

C

catalog panel: Area on the left side of the Music Library Screen that displays the organization of music files, the Master Library, playlists, and portable music players.
CD Info: CD data retrieved from an Internet database. If you are online, RealJukebox connects to the Internet and retrieves your CD's title, the artist's name, track titles, etc. This information is automatically saved when you record your CD.
CD Streamer: A program that records tracks from CDs and saves them as music files.
check box: RealJukebox's Record/Play check boxes let you determine which tracks to play or record (checked) and which ones to skip (unchecked).
Clipboard: The clipboard is a temporary storage place that holds only one set of cut or copied items at a time. The last items you cut or copied are stored on the clipboard.
contents panel: The area on the right side of the Music Library Screen that displays the contents of the item currently selected in the catalog panel.
continuous play: When this option is selected, RealJukebox plays your CD, album, or Playlist repeatedly (in listed order) until you stop playback.

D

digital: Sound information can be represented as a data stream of values. The original sound wave is sampled (measured) many times a second and resulting values are stored as computer 0's and 1's. To listen to the sound, the values must be converted back into an analog waveform using a digital to analog converter.
digital audio extraction: If your CD ROM supports this feature, RealJukebox can read the digital music data directly from your CD, bypassing your sound card for the best possible sound quality.

E

encode (encoding): The second step in digital CD recording, encoding is the process of converting music data into music files so RealJukebox can play your tracks. (See extraction, below.)
extraction: The first step in digital CD recording, extraction is the process of reading the raw music data from your CD. The next step in the recording process is encoding, described above.

F

file type: A file's "type" tells your computer which programs can use the file. When you click a link or a file, Windows checks to see what program is associated with that file type and automatically launches that program (for example, double-clicking on a.rmx file should launch RealJukebox and begin to play a track).
firewall: Security devices used to protect companies from unauthorized access to their servers. A firewall ensures that all communication between an organization's network and the Internet conform to the organization's security policies using either proxy services or packet filtering.
format: See "music file formats."
"frames": Unit of measurement for audio data. Each individual "frame" equals 1/75th of a second of information.
G
genre: Music type or category: Rock, Classical, Country, Jazz, Pop, etc.
graphic equalizer: Display that allows you to fine-tune your audio by increasing or decreasing the volume within specific frequency ranges.
group (grouping): RealJukebox's method for organizing tracks in the Music Library: by Genre, Artist, Album, etc.

H

Header Bar, Headers: The bar just above the Contents Panel or track list in the Music Library screen. With a Group, Playlist, or All Tracks open, it contains the headers Track Name, Album, Artist, etc. You can click a header to sort tracks by header criteria.
