The invention relates to a method for decompressing a compressed audio signal. In the compression of an audio signal, samples of the audio signal are taken, the samples are compiled into sample sets comprising a given number of samples, and the sample sets are subjected to time-to-frequency conversion, to form spectrum components. In the method, the spectrum components are subjected to frequency-to-time conversion to form a decompressed audio signal, only some of the spectrum components formed in the time-to-frequency conversion being used in the frequency-to-time conversion.
