The present invention relates to a method and a device for signal processing for effectively playing an audio signal and, more specifically, to a method and a device for audio signal processing for implementing, with a small amount of computation, binaural rendering for playing a multi-channel or multi-object audio signal with a stereo. To this end, the present invention provides the method for audio signal processing and the device for audio signal processing by using the same, the method comprising the steps of: receiving multi-audio signals including multi-channel or multi-object signals, wherein each of the multi-audio signals includes a plurality of sub-band signals and the plurality of sub-band signals include signals of a first sub-band group having a low frequency and signals of a second sub-band group having a high frequency on the basis of a pre-set frequency band; receiving at least one parameter corresponding to each sub-band signal of the second sub-band group, wherein at least one parameter is extracted from binaural room impulse response (BRIR) sub-band filter coefficients corresponding to each sub-band signal of the second sub-band group; and performing tapped-delay line filtering for the sub-band signals of the second sub-band group by using the received parameters. |
