Glossary

■ Sampling frequency and number of

quantized bits

When digitizing an analog audio signal, the number of times the

signal is sampled per second is called the sampling frequency, while

the degree of fineness when converting the sound level into a numeric

value is called the number of quantized bits. The range of rates that

can be played back is determined based on the sampling rate, while

the dynamic range representing the sound level difference is

determined by the number of quantized bits. In principle, the higher

the sampling frequency, the wider the range of frequencies that can be

played back, and the higher the number of quantized bits, the more

finely the sound level can be reproduced.

■ WAV

Windows standard audio file format, which defines the method of

recording the digital data obtained by converting audio signals. It does

not specify the compression (coding) method so a desired

compression method can be used with it. By default, it is compatible

with the PCM method (no compression) and some compression

methods including the ADPCM method.

■ WMA

An audio compression method developed by Microsoft Corporation. It

employs the irreversible compression method, which achieves a high

compression rate by thinning out the data of hardly audible part to the

human ears. It is said to be capable of compressing the data quantity

by about 1/22 (64 kbps) while maintaining a similar audio quality to

music CD.

■ “x.v.Color”

A color space standard supported by HDMI version 1.3. It is a more

extensive color space than sRGB, and allows the expression of colors

that could not be expressed before. While remaining compatible with

the color gamut of sRGB standards, “x.v.Color” expands the color

space and can thus produce more vivid, natural images. It is

particularly effective for still pictures and computer graphics.
