1. A computer-implemented method for audio processing, the method comprising:
obtaining a binaural room impulse response (BRIR) of an acoustic space;
receiving an input audio signal;
separating the input audio signal into low-frequency components and high-frequency components;
dividing the BRIR of the acoustic space into a first portion that occurs before a first time and a second portion that occurs after the first time;
generating a first component of an output audio signal based on the high-frequency components of the input audio signal and the first portion of the BRIR;
generating a second component of the output audio signal based on the high-frequency components of the input audio signal and the second portion of the BRIR;
generating a third component of the output audio signal based on the low-frequency components of the input audio signal and the BRIR; and
outputting the output audio signal.
