Audio signal processing method and device
The present invention relates to a method and an apparatus for processing an audio signal, and more particularly, to a method and an apparatus for processing an audio signal, which synthesizes an object signal and a channel signal and effectively binaural-render the synthesized signal.To this end, the present invention provides a method for processing an audio signal, including: receiving an input audio signal including a multi-channel signal; receiving filter order information variably determined for each subband of a frequency domain; receiving block length information for each subband based on a fast Fourier transform length for each subband of filter coefficients for binaural filtering of the input audio signal; receiving Variable Order Filtering in Frequency-domain (VOFF) coefficients corresponding to each subband and each channel of the input audio signal per block of the corresponding subband, a total sum of lengths of the VOFF coefficients corresponding to the same subband and the same channel being determined based on the filter order information of the corresponding subband; and filtering each subband signal of the input audio signal by using the received VOFF coefficients to generate a binaural output signal and an apparatus for processing an audio signal by using the same.
