Directional emphasis in ambisonics
We describe an ambisonics enhancement method that increases the signal
strength in specified directions at low computational cost. The method can be
used in a static setup to emphasize the signal arriving from a particular
direction or set of directions. It can also be used in an adaptive arrangement
where it sharpens directionality and reduces the distortion in timbre
associated with low-degree ambisonics representations. The emphasis operator
has very low computational complexity and can be applied to time-domain as well
as time-frequency ambisonics representations. The operator upscales a
low-degree ambisonics representation to a higher degree representation
