(SBR) Guessing the nontransmitted higherfrequency 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 upperfrequency range without lots of bits. It was developed byCoding Technology (http://codingtechnology.com/), and isuseful for medium and high quality coding at low and mediumdata rates. It is used by Digital Radio Mondiale and MP3Pro.
