Nearfield binaural synthesis and ambisonics

Ambisonic encodings can be rendered binaurally, as well as for speaker arrays. We first consider how binaural signals can be calculated from high-order Ambisonic encodings of general soundfields containing near and far sources. For sufficently near sources we identify an error resulting from the limited field of validity of the freefield harmonic expansion. A modified expansion is derived that can render such sources without error.
