The reverberation algorithm is usually an LTI system. The room in the concert hall does not change, so the response does not change over time. However, this can lead to colouration and instability due to feedback caused by the close proximity of the microphones and speakers. Some time-varying systems can solve this problem. This paper implements a new time-varying variable reverberation algorithm on bela, based on a combination of delay-line, lowpass filter and comb filter and feedback, for reverberation enhancement systems.
