Mixed-order Ambisonics (MOA) combines horizontal 2D higher-order Ambisonics (HOA) with lower order periphonic (3D) Ambisonics. Using MOA for spherical microphone arrays permits, compared to HOA, the improvement of horizontal source directivity while retaining some directivity for elevated sources. Because MOA does not capture all source directions in the same way, performance measures should be split into horizontal and vertical characteristics. (i) Reproduced power and (ii) spatial aliasing error as well as (iii) white noise gain and (iv) directivity index are averaged over horizontal sources and elevated sources.
