What are you calling 'actual' bitrate?  The bitrates shown by SbS
aren't estimates, they're merely the rate at which the data needs to
stream based on file size and track time.

For redbook audio, of 44.1 kHz, 16 bit stereo, the uncompressed bitrate
is:

44,100 * 16 * 2 / 1000 = 1411 kbps

The computed bitrate in SbS for lossless files is:

file_size_in_bytes * 8_bits_per_byte / track_time_in_seconds / 1000

For example, a track of 8:48 with a file size of 60,023,175 bytes:

60,023,175 * 8 / 528 / 1000 = 909 kbps
