Localization in Wave Field Synthesis and higher order Ambisonics at different positions within the listening area

Sound field synthesis methods try to synthesize a desired sound field within an extended listening area. If this task can be complied, the perception of a listener placed within the listening area will not differ from his/her auditory perception within a real sound field. Due to the practical limitation in the number of loudspeakers than can be applied for sound field synthesis methods, the produced sound field is in most cases only indistinguishably from the real sound field in a small area and/or under a certain frequency.
