Additional Information
Number of quantization bits
The number of quantization bits is one factor
in the overall sound quality; the higher the
bit-depth , the better the sound quality. How-
ever, increasing the bit-depth also increases
the amount of data and therefore storage
space required.
Packet write
This is a general term for a method of writing
on CD-R, etc., at the time required for a file,
just as is done with files on floppy or hard
discs.
VBR
VBR is short for variable bit rate. Generally
speaking CBR (constant bit rate) is more
widely used. But by flexibly adjusting the bit
rate according to the needs of audio compres-
sion, it is possible to achieve compression-
priority sound quality.
WAV
WAV is short for waveform. It is a standard
audio file format for Windows
WMA
WMA is short for Windows Media" Audio
and refers to an audio compression technol-
ogy that is developed by Microsoft Corpora-
tion. WMA data can be encoded by using
Windows Media Player version 7 or later.
