Convolution reverb is a process used for digitally simulating reverberation. Strange used the Bricasti and Eventide Reverb 2016 mixing tools for "brighter" reverberation. This space provided unique acoustics and a natural 3-second reverberation. "Flanging", "chorus" and "reverberation" (reverb) are all delay-based sound effects. Complex sound wave behaviors include absorption, reverberation, diffraction, and refraction. Active sonar have two performance limitations&colon; due to noise and reverberation. These plugins provide a combination of delay, sound effect, and reverberation effects. The sound consequently has long sustain and reverberation. Dereverberation is the process of reducing the level of reverberation in a sound or signal. This it excludes reverberation and towing noise for example. Advanced sound effects such as reverberation and chorus are not supported in hardware. The stereo mixes include heavier use of reverberation effects than the mono. The team also made changes to the audio, such as introducing sound occlusion and reverberation. This is useful for reverberation and other signal processor effects. Several systems have been developed to produce or to simulate reverberation.
