Abstract:
A method (900) for processing an audio signal includes: decomposing (901) an audio signal (602a, 602b) comprising spatial information into a set of audio signal components; and processing (902) a first subset (606a) of the set of audio signal components according to a first processing scheme (603) and processing a second subset (606) of the set of audio signal components according to a second processing scheme (609) different from the first processing scheme (603), wherein the first subset (606a) comprises audio signal components corresponding to at least one frontal signal source (M) and the second subset (606) comprises audio signal components corresponding to at least one ambient signal source (SL, SR); and wherein the second processing scheme (609) is based on crosstalk cancellation.
