Spectral Band Replication
<audio, compression> (SBR) Guessing the nontransmitted higher frequency
range of a compressed audio file by some helper bits (transmiited with the
stream) and the transmitted base band. SBR allows a restoration (not
reconstruction) of the upper frequency range without lots of bits. It was
developed by
Coding Technology, and is useful for medium and high quality coding at
low and medium data rates. It is used by Digital Radio Mondiale and MP3 Pro.
