Audio rendering using 6-dof tracking

A six-degrees-of-freedom sound source tracking system comprising:

• a processor configured to:
• receive a spatial audio signal, the spatial audio signal representing at least one sound source, the spatial audio signal including a reference orientation;
• receive a 3-D motion input from a motion input device, the 3-D motion input representing a physical movement of a listener with respect to the at least one spatial audio signal reference orientation;
• generate a spatial analysis output based on the spatial audio signal;
• generate a signal forming output based on the spatial audio signal and the spatial analysis output;
• and
• generate an active steering output based on the signal forming output, the spatial analysis output, and the 3-D motion input, the active steering output representing an updated apparent direction and distance of the at least one sound source caused by the physical movement of the listener with respect to the spatial audio signal reference orientation;
• and
• a transducer to transduce the audio output signal into an audible binaural output based on the active steering output.

At least one machine-readable storage medium, comprising a plurality of instructions that, responsive to being executed with processor circuitry of a computer-controlled six-degrees-of-freedom sound source tracking device, cause the device to:

• receive a spatial audio signal, the spatial audio signal representing at least one sound source, the spatial audio signal including a reference orientation;
• receive a 3-D motion input, the 3-D motion input representing a physical movement of a listener with respect to the at least one spatial audio signal reference orientation;
• generate a spatial analysis output based on the spatial audio signal;
• generate a signal forming output based on the spatial audio signal and the spatial analysis output;
• generate an active steering output based on the signal forming output, the spatial analysis output, and the 3-D motion input, the active steering output representing an updated apparent direction and distance of the at least one sound source caused by the physical movement of the listener with respect to the spatial audio signal reference orientation;
• and
• transduce an audio output signal based on the active steering output.
