METHOD FOR ARTIFICIAL REVERBERATION GENERATION AND APPARATUS THEREOF

摘要

The present invention relates to a method for generating a low computation artificial reverberation, and an apparatus therefor. In particular, a low computational artificial reverberation is generated so as to generate a more natural reverberation by performing full-pass filtering on a sound signal while changing a phase response with time. An apparatus and method are provided.;To this end, the present invention includes a time delay unit for delaying and outputting the input sound signal by a predetermined delay value; A low pass filtering unit for low pass filtering the time signal received from the time delay unit to adjust the reverberation time for each frequency of the sound signal; In order to prevent the energy of the sound signal from being concentrated at a constant resonant frequency, the band-pass filtering is performed while changing the phase response with respect to the sound signal received from the low pass filtering unit over time, and the filtered signal is subjected to the time. It provides a low-cost artificial reverberation generating device comprising a; (feedback) to the delay unit, and a time-varying full-band filtering unit for outputting the filtered signal as an artificial reverberation signal.;Artificial reverberation, time-varying full band pass filter
