AB  - This paper introduces Binaural Rendering of Audio by Duplex Independent Auralized Listening (Bi-RADIAL), a new scheme for the reproduction of 3D sound over headphones. Principles, considerations, and methods of Bi-RADIAL decoding and their application within the binaural rendering of Virtual Ambisonics is discussed. Three methods of delivering Bi-RADIAL Ambisonics are compared and the advantages of exploiting a Bi-RADIAL scheme over traditional binaural-based Ambisonic playback are highlighted. Simulation results for standard and Bi-RADIAL Ambisonic decoders are given using a perceptual based comparison of their frequency spectra. Analysis is made for 1st, 3rd, and 5th order decoders considering both basic and maxrE weighting schemes. Results show a clear improvement in spectral reconstruction when using a Bi-RADIAL decoder.
