The average data rate in bytes per second can be read from memory, see the
extra parameter. This variable contains the byte rate for all codecs. To get the bitrate of the file,
multiply the value by 100, and to get the kilobitrate, make a rounded divide by 10.
The bitrate calculation is not automatically reset between songs, but it can also be reset without
a software or hardware reset by writing to SCI_DECODE_TIME.
