The invention describes a digital adaptive Transformationscodierverfahren for the transmission and / or storing acoustic signals, specifically music signals, are transformed Nals wherein N samples of the acoustic Sig into M spectral coefficients which are quantized and encoded after division into frequency groups. The invention is characterized in that each frequency group is used for the description of the rough profile of the spectrum of the quantized maximum value. Further, all values ​​of a frequency group are allocated the same bit number, and in that the bit allocation is carried out on the individual frequency groups corresponding to the quantized maximum value occurring in this frequency group. Furthermore, a multi-signal processor system is particularly described for imple tion of this process. In a digital adaptive transform coding process for Transmitting and / or Storing acoustic signal in Particular musical signal, scanning values ​​of the N acoustic signals are Transformed into spectral coefficients M Which are divided into fre quency groups, and then quantified and coded. .According To the Invention, the quantified maximum value of each fre quency group is used to characterize the general course of the spectrum. In addition, the same bit number is allocated to all values ​​of a frequency group and the bits are allocated to the individual frequency groups on the basis of the quantified maximum value in the frequency respectivement group. So Described is a multi-signal processing system, in Particular for Implementing the process.
