Additional Information

MS ADPCM

This stands for Microsoft adaptive differential pulse code modulation, which is the signal re- cording system used for the multimedia soft- ware of Microsoft Corporation.

Multi-session

Multi-session is a recording method that al- lows 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-ses- sion is a method of recording more than 2 ses- sions 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. How- ever, increasing the bit-depth also increases the amount of data and therefore storage space required.

OPP

OPP is short for Object Push Profile. This pro- file is used for transferring the phonebook data, schedule data and so on between de- vices featuring Bluetooth wireless technology.

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.

SDAP

SDAP is short for Service Discovery Applica- tion Profile. This profile is used for searching the services the device featuring Bluetooth wireless technology supports.

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. Windows Media and the Windows logo are tra- demarks or registered trademarks of Microsoft Corporation in the United States and/or other countries.
