Describes the challenges of binaural audio through headphones (BAH) and loudspeakers (BAL), recent solutions to these challenges, and the state of the art of binaural processing and content development tools. In particular, BACCH 3D Sound processing is described, which relies on optimal crosstalk cancellation filters, head tracking and automatic individualization to deliver accurate 3D imaging from binaural audio. The author then describes the recently developed BACCH-HP headphones processing, which significantly enhances the robustness of 3D imaging and the ability to head-externalize binaural audio. The powerful BACCH-dSP software is shown, which allows designing BACCH filters for BAL and BAH, processing binaural audio, translational and rotational head tracking, and 3D mixing, to illustrate the talk and demonstrate the technologies.
