Apparatus and a method for compressing data that represent a time-dependent signal that includes a multiplicity of time-dependent signal elements, wherein a multiplicity of spectra are received, where each spectrum corresponds to one of the time-dependent signal elements, and where each spectrum includes a multiplicity of frequencies fj and a multiplicity of amplitudes of the multiplicity of frequencies, wherein a compressed data record is generated, wherein a respective number of coefficients of an autoregressive model for the multiplicity of amplitudes of each of the multiplicity of frequencies is ascertained, and wherein the compressed data record is generated, where the compressed data record includes at least the number of coefficients and the frequencies associated with the coefficients.
