1. A method for binaurally rendering a soundfield, the method comprising:
receiving, from a mixer, N virtual loudspeaker feeds representing the soundfield for binaural rendering, wherein N>1; and
rendering, using one or more head related transfer functions (HRTFs), a stereo binaural signal, wherein the rendering comprises transforming the N virtual loudspeaker feeds into the stereo binaural signal by determining N signals for each of left and right ears and generating the stereo binaural signal by summing the N signals for each of the left and right ears, wherein the stereo binaural signal comprises left and right output signals, and wherein the rendering further comprises applying a plurality of time delays.
