摘要： In a process for coding stereophonic spectral values, the stereophonic spectral values are first grouped into scaling factor bands (28) to which are associated scaling factors. Sections are then formed which consist of at least one scaling factor band (28). The spectral values are coded in at least one section with a coding table associated to the section among a plurality of coding tables associated each to a coding table number. The number of the used coding table is transmitted together with the coded stereophonic spectral values as supplementary information. At least one additional coding table number is provided which does not relate to a coding table but gives information relevant to the section to which the coding table is associated. A process for decoding stereophonic spectral values which have been partially coded by an intensity stereo process and contain supplementary information uses the relevant information given by the additional coding table numbers to undo the coding of the stereophonic spectral values.
