AAC stands for "Advanced Audio Coding", which is an audio compression method use
with the video compression of digital broadcasting, etc.
Stands for "Compact Disc – Digital Audio". The CD-DA is usually called "CD".
Music CD in which the character information such as the disc titles, artist names, track
titles, etc. is recorded.
This is an audio reproduce system developed by DTS, Inc., and is capable of
reproducing high quality 3D surround audio using two speakers. It makes it possible to
enjoy feeling of presence of 3D surround from a 2-channel stereo input source.
An audio compression method developed by Fraunhofer IIS, Germany. It achieves
a high compression rate by thinning out the data of the sound that is less audible
to human ears. It can compress music CD data into about 1/11 (128 kbps) while
maintaining similar audio quality.
PCM stands for "Pulse Code Modulation", which is a system for converting analog audio
signals into digital data. The CD (CD-DA) utilises the PCM system with a sampling
frequency of 44.1 kHz.
Standard for interfacing between the PC and peripheral devices. This system is
compatible with USB 1.1 and 2.0.
Adapter for connecting more than one USB device simultaneously.
Standard for controlling a USB device from a PC. Also, refers to the action that a PC
recognizes a USB device connected to it as an external storage device.
Technology for assigning the bits by varying their quantity according to the amount of
music information.
Stands for "Windows Media™ Audio", which is an audio compressed encoding system
developed by Microsoft Corporation.
Number of times analog signal is converted into digital signal per second. It is 44.1 kHz
with music CD. In general, higher sampling frequencies offer higher audio quality.
Information written in audio file, including the title name, artist name, album name and
genre.
Figure expressing the amount of information per second. A higher bit rates offer higher
audio quality.
