Apparatus and Method for the direct decomposition of Multichannel Environment for processing audio Signals

摘要

An apparatus is disclosed for generating one or more signals of Audio Output channels depending on two or more signals of audio INPUT channels. Each of the two or more channels of audio INPUT signals includes portions of the signal and direct Signal portions of the Environment.The Apparatus includes a determination Unit (110) filters to determine a Filter through a first estimate of the information of Power Spectral density and a second information through the estimation of Power Spectral density.Also, The Apparatus includes a Signal Processor (120) to generate the above one or more signals of Audio Output channels through the application of the filter to the two or more signals from the audio INPUT channels.The First Information of Power Spectral Density indicates the information of Power Spectral Density on two or more signals from the audio INPUT channels and the second information of Power Spectral Density indicates the information of Power Spectral density. On the portions of the signal Environment of two or more signals of audio INPUT channels.Or the First Information of Power Spectral Density indicates the information of Power Spectral Density on the two or more signals of the input channels of audio Information and the second information indicates the Spectral Density Power Spectral density. So on the direct Signal portions of two or more signals of audio INPUT channels.Or the First Information of Power Spectral Density indicates the information of Power Spectral Density on the direct Signal portions of two or more signals of audio INPUT channels of Information and the second information indicates the Power Spectral density The Power Spectral density of the signal Environment of portions of two or more signals of CanaI audio INPUT.
