FIELD: means of audio signal processing.
SUBSTANCE: invention relates to means of audio signal processing. Each of the two or more audio input channel signals comprises direct signal portions and ambient signal portions. Apparatus for generating the one or more audio output channel signals comprises a filter determination unit for determining a filter by estimating first power spectral density information and by estimating second power spectral density information. Moreover, the apparatus comprises a signal processor for generating one or more output audio channel signals by applying the filter on the two or more audio input channel signals. First power spectral density information indicates power spectral density information on the two or more audio input channel signals.
EFFECT: technical result is to improve efficiency of multichannel direct-ambient decomposition for audio signal.
