US Patent 10382879 Virtual sound field

Producing a virtual sound field may include receiving an audio signal associated with a remote sound source within a remote environment. The audio signal may be defined or recorded as a binaural recording and recorded from a remote set of binaural microphones. The audio signal may be indicative of a position of the remote sound source relative to the remote set of binaural microphones within the remote environment. Producing the virtual sound field may include determining a virtual position relative to the position of the remote sound source within the remote environment, generating a virtual sound field audio signal which simulates audio representing the remote sound source perceived from the virtual position within the remote environment relative to the position of the remote sound source within the remote environment, and playing back the virtual sound field to simulate the remote sound source as perceived from the virtual position.
