Abstract
The present invention relates to an audio signal processing apparatus and an audio signal processing method to perform binaural rendering. To this end, provided are an audio signal processing apparatus to perform binaural filtering an input audio signal, including: a first filtering unit configured to filter the input audio signal by a first lateral transfer function to generate a first lateral output signal; and a second filtering unit configured to filter the input audio signal by a second lateral transfer function to generate a second lateral output signal, wherein the first lateral transfer function and the second lateral transfer function are generated by modifying an interaural transfer function (ITF) with respect to the input audio signal and an audio signal processing method using the same.
