Method and apparatus for modeling room impulse response

摘要

Disclosed are a method and apparatus for modeling a room impulse response. A method of modeling a room impulse response according to an embodiment of the invention includes receiving a sound pressure signal that is obtained by a microphone when an impulse-typed sound source is excited and detecting a room impulse response; determining boundaries between a plurality of intervals of the room impulse response such that the room impulse response is divided into the plurality of intervals on a time domain; and modeling the room impulse response using a different modeling method for each of the plurality of divided intervals. According to this invention, when a room impulse response is modeled, it is possible to decrease the number of parameters while maintaining accuracy.
