Glossary of Digital Audio Terms

Bass

Bass is the low-range area of the sound spectrum where low musical notes and sounds are located.

Increasing the bass value will make the low vocals and drums more prominent in your music. You can select

the amount of bass in your music by selecting various equalizer options.

Bitrate

Bitrate denotes the number of bits per second used

by a digital music file. The size and quality of a

compressed digital audio file is determined by the

bitrate used when encoding the file. The higher the

bitrate used, the higher the sound quality, and the

larger the file size. For example, with MP3, a bitrate

of 128kbps (128,000 bits per second) is generally

thought of as “CD quality”, and takes up about 1

megabyte (MB) per minute of music. At a 64kbps

bitrate, the sound quality is similar to that of an FM

radio signal, but you can get approximately two

minutes of music in that same 1MB of storage

space. CD audio has a bitrate of 1.4Mbits per

second (1,400,000 bits/second).

Codec

Depending on the context and kind of technology involved, codec can be defined as a compressed digital

audio file format (like MP3, Red Book, etc.), a “coding/decoding” chip used to translate between digital and

analog transmissions (used in modems), or a compression/decompression algorithm. Codecs compress

audio data into a file, often for efficient transmission over a network, and then decode it for playback. While

all the codecs perform similar compression of digital audio, there are differences in the technology.

The RioVolt SP65 supports the following digital audio codecs:

•MP3

•CD Audio (Red Book)
