Terms
Packet writeThis 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.
Bit rateThis expresses data volume per second, or bps (bits per second) units. The higher the rate, the more information is available to reproduce the sound. Using the same encoding method (such as MP3), the higher the rate, the better the sound.
Multi-sessionMulti-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 in
one disc.
