Additional Information
MP3
MP3 is short for MPEG Audio Layer 3. It is an audio compression standard set by a
working group (MPEG) of the ISO (International Standards Organization). MP3 is able
to compress audio data to about 1/10th the level of a conventional disc.
MS ADPCM
This stands for Microsoft adaptive differential pulse code modulation, which is the
signal recording system used for the multimedia software of Microsoft Corporation.
Multi-session
Multi-session is a recording method that allows additional data to be recorded later.
When recording data on a CD-ROM, CD-R or CD-RW, etc., all data from beginning to
end is treated as a single unit or session. Multi-session is a method of recording more
than 2 sessions on one disc.
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. However, 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
compression, 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
technology that is developed by Microsoft Corporation. WMA data can be encoded by
using Windows Media Player version 7 or later.
