Claim:
1. A method comprising: providing at least one processing unit comprising a plane-wave decomposing section and a playback section; receiving, at the plane-wave decomposing section, audio data generated via an array of microphones, the audio data representing an acoustic scene; performing plane-wave field decomposition on the audio data to decompose the audio data into a plurality of signals representing audio components of the acoustic scene arriving from a plurality of directions, using the plane-wave decomposing section; and rendering the audio components for a listener based on the plurality of directions of the audio components, using the playback section, wherein the step of rendering the audio components includes retrieving or generating at least one head-related transfer function for each of the plurality of directions, rendering the audio component arriving from each of the plurality of directions using a respective retrieved or generated head-related transfer function, and combining the rendered audio components to generate a total output stream.
