FIELD: physics.
SUBSTANCE: received audio data may include the first set of the frequency coefficients and the second set of the frequency coefficients. The spatial parameters of, at least, a part of the second set of the frequency coefficients may be estimated, at least, partially based on the first set of the frequency coefficients. The estimated spatial parameters can be applied to the second set of the frequency coefficients to generate the second modified set of the frequency coefficients. The first set of the frequency coefficients may correspond to the first frequency band, and the second set of the frequency coefficients may correspond to the second frequency band. The combined frequency coefficients of the composite binding channel may be based on the frequency coefficients of two or more channels. It is possible to calculate a mutual correlation between the frequency coefficients of the first channel and the combined frequency coefficients.
EFFECT: creating means that provide improved audio processing.
