Abstract

The invention relates to a sound field generator and a method of generating a sound field using the same. More particularly, the invention relates to a sound field generator and a method of generating the same, which can apply a filter in consideration of a masking effect in a time domain to a room impulse response, remove inaudible data depending on a frequency in a signal obtained by multiplying the room impulse response by an input signal in a frequency domain, and remove a signal block having a lower level than a level of a background noise block among output signal blocks to considerably reduce computational complexity required for performing a convolution, making it possible to generate an accurate sound field by minimizing sound quality distortion while implementing a real-time sound field generating system.
