Encoding, or “ripping” and encoding

Encoding, sometimes referred to as “ripping” and encoding, refers to extracting audio from a music CD (ripping), and converting it (encoding) into a compressed digital audio format like MP3 or WMA.

Firmware

Firmware is software—programs or data—that has been written onto read-only memory (ROM). Firmware is a combination of software and hardware that is comparable to an operating system on a computer. The RioVolt firmware controls everything from the liquid crystal display and codec support to the RioVolt’s other functions.

ID3 Tag

The ID3 tag is the part of the encoded MP3 file that contains information about the digital music file such as song title, artist, album title, encoding bitrate, track time duration, and so on.

MP3

MP3 is short for Moving Pictures Experts Group Audio Layer 3. MP3 is the most well known compressed digital audio file format. This format allows for near “CD quality” sound, but at a fraction of the size of normal audio files. MP3 conversion of an audio track from CD-ROM reduces the file size by approximately a 12:1 ratio with virtually no perceptible loss in quality. This digital sound encoding and compression process was developed by the Fraunhofer Institut fur Integrierte

Schaltungen and Thomson Multimedia. MP3 compression removes the redundant and irrelevant parts of a sound signal that the human ear doesn't hear. The MP3 encoding process is well suited for the transfer of high quality audio files with small file size over the Internet.

The specification for audio (CD-DA) compact discs.

Treble

Treble is the high notes of the sound spectrum. Increasing the treble value will raise the levels of the high sounds in your music files.

VBR

Variable Bitrate (VBR) encoding converts tracks at a variable rate, using higher bitrate encoding for complex portions and lower bitrate encoding for pauses in songs.

WMA

Windows Media Audio (WMA) is the compressed audio format created by Microsoft as an alternative to MP3. WMA offers greater file compression than MP3, enabling you to store more music on your PC or writable CDs.
