Process for transmitting and/or storing digital signals of multiple channels

A process for transmitting and/or storing digital signals from K input channels, in which

• sampling values of signals from the time domain are transmitted in blocks into the frequency domain (in spectral values), and
• said spectral values are coded and combined into a bit stream which is transmitted and/or stored and subsequently decoded and transmitted back into K output channels in the time domain,
• wherein a variable number of spectral data channels (TSC, transmitted spectral data) are formed in segments during the coding in dependence of the spectral information of the blocks of the individual input channels, with the number of NTSC (number of transmitted spectral channels) of the spectral data channels per segment being less than or the same as the number K of the input and output channels, said number of NTSC and the structure of said spectral data channels being included in the bit stream as information (SEGMENT.sub.-- DATA) and following transmission of said bit stream, said K output channels are combined in the decoder in segments from the transmitted spectral data channels (TSC) with the aid of the information (SEGMENT.sub.-- DATA).
