This paper describes the main features of the NBC advanced coding system (CD 13818-7). NBC combines the coding efficiency of a high resolution filter bank, prediction techniques and Huffmann coding with additional functionalities aimed to deliver broadcast quality at very low data rates (64 kb/s per channel).enAACadvanced audio codingdata compressiondata reductionDatenkomprimierungDatenreduktionlow bitrate audio codingMPEGMPEG-2perceptual audio codingpsychoacousticPsychoakustikToncodierung006621conference proceeding
