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 (http://codingtechnology.com/), 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.
