Spectral Band Replication


Spectral Band Replication

(audio, compression)(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, and isuseful for medium and high quality coding at low and mediumdata rates. It is used by Digital Radio Mondiale and MP3 Pro.
