Abstract: The invention relates to a method and a device for changing the temporal length and/or the tone pitch of a discrete audio signal. For improving the sound quality in such a method, according to the invention it is proposed that the audio signal be split into at least two partial signals and, in each case, fed to a processing channel; that the temporal length and/or the tone pitch of the partial signals be changed separately in different ways; and that the separately-processed partial signals then be combined into an output signal. Alternatively, according to the invention it is proposed that the audio signal be fed to at least two parallel processing channel, that the temporal length and/or the tone pitch of the audio signals be changed separately in different ways, that the separately-processed audio signals be split into two partial signals in each case, and that an output signal then be formed through combination of, in each case, at least one partial signal of each processing channel.
