摘要：FIELD: physics. ^ SUBSTANCE: processor or method of processing dynamic properties of audio employs a mechanism or sequence of retuning operations for fast adaptation to changes in content in the audio signal. The retuning signal can be generated by analysing the audio signal itself, or retuning can be performed based on an external event, such as changing the channel on a television receiver or changing the input selection on an audio/video receiver. If there is an external activating signal, one or more features of the state of the dynamic property processor for the current audio source can be stored or associatively linked to such an audio source before switching to a new audio source. Further, if the system if switched back to the first audio source, the dynamic property processor can be retuned to a state stored earlier or approximation thereof. ^ EFFECT: adaptation to changes in content in an audio signal. ^ 14 cl, 6 dwg
