Abstract

A method of processing at least one input signal by a set of binaural filters such that the outputs are playable over headphones to provide a sense of listening to sound in a listening room via one or more virtual speakers, with the further property that a monophonic mix down sounds good. Also an apparatus for processing the at least one input signals. Also a method of modifying a pair of binaural filters to achieve the property that a monophonic mix down sounds good, while still providing spatialization when listening through headphones.
