Error correction of head-related filters

Abstract

A method for generating a final corrected head-related (HR) filter dataset, (A). The method includes obtaining a first corrected HR filter dataset, (B). Obtaining the first corrected HR filter dataset (B) includes: obtaining (s802) an initial HR filter dataset, (C); obtaining (s804) an extracted HR filter dataset, (D), extracted from the initial HR filter dataset, (C); obtaining (s806) a model, (E), of the extracted HR filter dataset, (D); generating (s808) a modelled HR filter dataset, (F), using the model, (E); selecting (s810) for correction one or more HR filters that are included in the initial HR filter dataset, (C), based on the modelled HR filter dataset, (F), and the extracted HR filter dataset, (D); and generating (s812) the first corrected HR filter dataset, (B) by correcting the selected one or more HR filters. Either the final corrected HR filter dataset (A) is the first corrected HR filter dataset (B) or the method further comprises generating the final corrected HR filter set (A) using the first corrected HR filter dataset (B).
