  S.D. Miller and F. Zhou have proved a balanced Voronoi summation formula for
GL$_N$ over $\mathbb Q$, which allows one to control the dimensions of the
Kloosterman sums appearing on either side of the Voronoi formula. In this note,
we prove a balanced Voronoi formula over an arbitrary number field, starting
with the Voronoi summation formula of A. Ichino and N. Templier over number
fields, allowing one to extend recent results on spectral reciprocity laws to
number fields, in special cases.
