What HOA does is define the 'point' to be larger at any frequency. We
don't need a larger 'point' at LF so FOA is usually sufficient at LF. At
mid & higher frequencies, HOA encoding allows a larger 'point' to be
defined.

Surely you mean that the point is smaller, and direction more precise with HOA.
I think by "point" he means the area where the soundfield is
reconstructed (with a certain error bound), higher orders yield a bigger
area. The area is frequency dependent - smaller at high frequencies.

Back to HOA encoding.
