AB  - Ambisonics is being used in applications such as virtual reality to render 3-dimensional sound fields over headphones through the use of virtual loudspeakers, the performance of which has previously been assessed up to third order. Through a localization test, the performance of first, third, and fifth order Ambisonics is investigated for optimized real and virtual loudspeaker arrays utilizing a generic HRTF set. Results indicate a minor improvement in localization accuracy when using fifth order over third though both show vast improvement over first. It is shown that individualized HRTFs are required to fully investigate the performance of Ambisonic binaural rendering.
