Implementation of Audio Reverberation Processing in Karaoke System Based on Room Acoustics Modeling

The formative principle of the audio reverberation on the basis of room acoustics modeling and usage of reverberation filters consisting of comb filters and all-pass filters is focused on to simulate phenomenon of reverberation. Based on the theory mentioned above, the reverberation in Karaoke System can be implemented, then the impacts on the reverberant system are analyzed by the test relevant parameters of the filters. Different reverberant effects can be generated by adjusting these corresponding parameters.
