Abstract

Ambisonic audio is converted to binaural audio based on head related impulse responses (HRIRs) associated with sound sources located symmetric with respect to a head of a listener. The HRIRs associated with sound sources located symmetric with respect to the head of the listener are mapped to HRIR pairs associated with sound sources located on one side of the head of the listener based on the symmetry of the sound source locations. A sequence of HRIRs based on the mapped left HRIRs or a sequence of HRIRs based on the mapped right HRIRs are input into a spherical harmonics converter which outputs respective left spherical harmonics or right spherical harmonics. Ambisonic audio is binauralized based on the left spherical harmonics and the right spherical harmonics.
