Abstract:
The method of capturing an audio scene includes acquiring sounds having first and second directivities to obtain first and second acquisition signals, respectively, the first directivity being higher than the second directivity, the steps of acquiring being performed simultaneously, and both acquisition signals together representing the audio scene; separately storing the first and second acquisition signals or mixing individual channels in the acquisition signals to obtain first and second mixed signal, respectively, and separately storing the first and second mixed signals, or transmitting the first and second mixed signals or the first and second acquisition signals to a loudspeaker setup and rendering the first mixed signal or the first acquisition signal using a loudspeaker arrangement having a first directivity and simultaneously rendering the second mixed signal or the second acquisition signal using a loudspeaker arrangement having a second directivity, the second loudspeaker directivity being lower than the first one.
