Claim of US Patent No. 10,129,685

1. A method for processing an audio signal, the method comprising:receiving an input audio signal;
obtaining block length information and number of blocks information of filter coefficients for each subband;
receiving filter coefficients for each of a subband index, a binaural filter pair index, a block index in the number of blocks, and a time slot index in each block having a length according to the block length information, wherein a total length of filter coefficients for a same subband index and a same binaural filter pair index is determined based on a filter order of the corresponding subband; and
filtering each subband signal of the input audio signal by using the received filter coefficients corresponding thereto.
