Virtual sound field
First Claim
1. A system for producing a virtual sound field, comprising:
- a communication interface receiving an audio signal associated with a remote sound source within a remote environment, wherein the audio signal associated with the remote sound source is defined as a binaural recording and recorded from a remote set of binaural microphones and wherein the audio signal associated with the remote sound source is indicative of a position of the remote sound source relative to the remote set of binaural microphones within the remote environment;
a processor determining a virtual position relative to the position of the remote sound source within the remote environment and 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
a local set of binaural speakers playing the virtual sound field audio signal to simulate the remote sound source as perceived from the virtual position relative to the position of the remote sound source within a local environment associated with the system for producing the virtual sound field.

Abstract
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.

11. A method for producing a virtual sound field, comprising:
-
receiving an audio signal associated with a remote sound source within a remote environment, wherein the audio signal associated with the remote sound source is defined as a binaural recording and recorded from a remote set of binaural microphones and wherein the audio signal associated with the remote sound source is indicative of a position of the remote sound source relative to the remote set of binaural microphones within the remote environment; 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 audio signal to simulate the remote sound source as perceived from the virtual position relative to the position of the remote sound source within a local environment. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system for producing a virtual sound field, comprising:
-
a communication interface receiving an audio signal associated with a remote sound source within a remote environment, wherein the remote sound source is a virtual sound source and the remote environment is a virtual environment, wherein the audio signal associated with the remote sound source is defined as a binaural recording and wherein the audio signal associated with the remote sound source is indicative of a position of the remote sound source relative to the remote environment; a processor determining a virtual position relative to the position of the remote sound source within the remote environment and 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 a local set of binaural speakers playing the virtual sound field audio signal to simulate the remote sound source as perceived from the virtual position relative to the position of the remote sound source within a local environment associated with the system for producing the virtual sound field. - View Dependent Claims (18, 19, 20)
