Abstract
A method () of processing audio in an immersive audio format comprising at least one height audio channel, comprising: obtaining () two height audio signals from at least a portion of the at least one height audio channel: modifying () a relative phase between the two height audio signals in frequency bands in which phase differences are predominantly out of phase to obtain two phase modified height audio signals: and playing back () the processed audio comprising the two phase modified height audio signals with at least two audio loudspeakers. The phase differences occur as a result of having monaural signals emanated from two audio loudspeakers at one or more listening positions symmetrically off-center with respect to the at least two loudspeakers, laterally spaced with respect to each of said one or more listening positions. The method allows perception of sound height/elevation without using overhead speakers.
