CONTROLLING SPATIAL AUDIO CODING PARAMETERS AS A FUNCTION OF AUDITORY EVENTS |
摘要 |
An audio encoder or encoding method receives a plurality of input channels and generates one or more audio output channels and one or more parameters describing desired spatial relationships among a plurality of audio channels that may be derived from the one or more audio output channels, by detecting changes in signal characteristics with respect to time in one or more of the plurality of audio input channels, identifying as auditory event boundaries changes in signal characteristics with respect to time in the one or more of the plurality of audio input channels, an audio segment between consecutive boundaries constituting an auditory event in the channel or channels, and generating all or some of the one or more parameters at least partly in response to auditory events and/or the degree of change in signal characteristics associated with the auditory event boundaries. An auditory-event-responsive audio upmixer or upmixing method is also disclosed. |
