Claim of US Patent No. 9,848,275

7. An apparatus for processing an audio signal for performing binaural rendering of an input audio signal including at least
one of a multi-channel signal and a multi-object signal, wherein the apparatus for processing an audio signal is configured
to:
receive type information of a filter set for binaural filtering of the input audio signal, the type of the filter set being
one of a finite impulse response (FIR) filter, a parameterized filter in a frequency domain, and a parameterized filter in
a time domain,

receive filter information for binaural filtering based on the type information, and
perform the binaural filtering for the input audio signal by using the received filter information, and
wherein when the type information indicates the parameterized filter in the frequency domain,
the apparatus for processing an audio signal receives subband filter coefficients having a length determined for each subband
of a frequency domain and filters each subband signal of the input audio signal by using the subband filter coefficients corresponding
thereto.
