Explanation of terms

MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data compression scheme,

using the “MPEG-1” video compression standard. It compresses the data

volume to about one eleventh its original size while maintaining sound

quality equivalent to a music CD.
WMA (Windows Media Audio)
This is audio compression technology developed by Microsoft

Corporation.
WMA data can be encoded using Windows Media

®

Player.

To encode WMA files, only use applications authorized by Microsoft

Corporation. If you use an unauthorized application, the file may not work

properly.
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at

regular intervals and expressing the height of the wave at each reading in

digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling

frequency”. The larger the value, the closer the reproduced sound is to the

original.

Dynamic range
The difference between the maximum undistorted sound level and the

minimum discernible level above the noise emitted by the device.
Bit rate
This is the amount of audio data recorded on a disc that is read in one

second.
Finalizing
This process enables CDs recorded with a CD recorder or drive to be

played by other players.
Linear PCM
This is an uncompressed PCM (Pulse Code Modulation) signal. Unlike

lossy compression audio sources such as MP3, no audio quality or

dynamic range deteriorates.
