Bit rate
Indicates the data amount per second. The rate is reflected in bps (bit per second).
64 kbps means 64000 bits of information per second. If the bit rate is large, that means a large
amount of information is used to play music. Comparing music of the same format (e,g.,
ATRAC3plus), 64 kbps data offers better sound quality than 48 kbps data. However, audio files
in formats such as MP3 have different encoding methods, and thus sound quality cannot be
determined by simply comparing the bit rate.
