| Abstract: | The applications of MaxxBass algorithm and EVB Phase Vocoder algorithm in virtual bass enhancement are in- troduced. And an virtual bass enhancement system based on VB Phase Vocoder algorithm is implemented, and then, the re- sult of the experiment is analyzed. The result shows that this virtual bass enhancement system can provide heavy bass effect, create the perfect environment different from the sound field, gain the effect is very obvious. |
