Reverb (PB only)

This effect simulates a spacious or acoustically live interior by simulating random reflections of a sound off of a surface. Using the Reverb Time option, specify the average time in milliseconds between the original audio and the reverberated audio. Use Diffusion to specify how much the effect scatters the original audio. More diffusion can make the audio sound further from the microphone. Set Decay to specify the amount of time it takes for the effect to subside. A longer decay simulates a larger space.
