AUXILIARY AUGMENTATION OF SOUNDFIELDS

摘要

A method for altering an audio signal of interest in a multi-channel soundfield representation of an audio environment, the method including the steps of: (a) extracting the signal of interest from the soundfield representation; (b) determining a residual soundfield signal; (c) inputting a further associated audio signal, which is associated with the signal of interest; (d) transforming the associated audio signal into a corresponding associated soundfield signal compatable with the residual soundfield; and (e) combining the residual soundfield signal with the associated soundfield signal to produce an output soundfield signal.
