Short for Reverberation. The dense collection of echoes which bounce off acoustically reflective surfaces in response to direct sound arriving from a signal source. Reverberation can also be created artificially using various analogue or, more commonly, digital techniques. (Click this link to view Reverb technique articles and hardware/software reverb product reviews.)
Reverberation occurs a short while after the source signal because of the finite time taken for the sound to reach a reflective surface and return — the overall delay being representative of the size of the acoustic environment.
The reverberation signal can be broadly defined as having two main components, a group of distinct ‘early reflections’ followed by a noise-like tail of dense reflections.
Inspired Acoustics Inspirata offers control over many reverb/room parameters.
