Method and apparatus for rendering ambisonics audio signal

This document describes a method (400) for rendering an ambisonics signal using a loudspeaker arrangement comprising S loudspeakers. The method (400) comprises: converting (401) a set of N ambisonics channel signals (111) into a set of unfiltered pre-rendered signals (211), where Ngt; 1 and Sgt; 1. Furthermore, the method (400) comprises performing (402) near field compensation (referred to as NFC) filtering on M unfiltered pre-rendered signals (211) of the set of unfiltered pre-rendered signals (211) to provide a set of S filtered loudspeaker channel signals (114) for rendering using corresponding S loudspeakers. 本文档描述了一种用于使用包括S个扩音器的扩音器布置来渲染高保真立体声信号的方法(400)。所述方法(400)包括：将一组N个高保真立体声声道信号(111)转换(401)成一组未滤波的预渲染信号(211)，其中，N>1并且S>1。此外，所述方法(400)包括：对该组未滤波的预渲染信号(211)中的M个未滤波的预渲染信号(211)执行(402)近场补偿(称为NFC)滤波，以提供一组S个经滤波的扩音器声道信号(114)，用于使用对应的S个扩音器进行渲染。
