1. A method for operating an audio device, in particular for carrying out a morphing process, wherein audio output data are generated from audio input data containing at least one sample and/or at least one block of samples by means of at least one function stored in a data device, wherein at least one parameter of the at least one function is changeable in operation of the audio device, the method comprising:
updating at least one item of topicality information of the at least one parameter, which information indicates a state of change (12, 13) of the at least one parameter, only after the change to the at least one parameter has been made; and
generating the audio output data depending on the topicality information of the at least one parameter based on the at least one changed parameter or the at least one unchanged parameter of the at least one function, wherein:
the at least one parameter with a latest topicality value is used for generating the audio output data,
the generating the audio output data depending on the topicality information of the at least one parameter comprises determining that the change to the at least one parameter cannot be completely processed in an available time window and, based upon the determination that the change to the at least one parameter cannot be completely processed in an available time window, interrupting the morphing process and generating the audio output data based on the unchanged parameter and completing the change to the at least one parameter in a next available time window, and
the at least one changed parameter or the at least one changed parameter samples block of the function is used for the generation of the audio output data upon determining that the topicality information of the pertinent parameter or parameter samples block corresponds to a defined value, in particular corresponds to the latest value.
