ReaVerb is a VST plug-in that is supplied with REAPER. Reverb itself is a time-based effect, and ReaVerb uses a type of reverb known as convolution reverb to create the illusion of space. This section will introduce you to the basics of using ReaVerb. After that, it has more features that you can explore for yourself. Most reverbs attempt to simulate the effect that the acoustic environment of, say, a hall or a room would have on sound. However, the mathematics required is complex, so that few come close to sounding like real acoustic rooms. Reverb plug-ins vary not only in their essential quality but also in the scope of their applications. Convolution reverb can give you realistic reverb on a budget. It uses impulse responses of real acoustic spaces. This is done by first generating a signal in the required environment and then recording the result. ReaVerb allows you to both use recorded impulses from real environments to create your reverb, together with something closer to traditional reverb techniques to modify that sound further.
To use convolution reverb you will need impulse wave files. Search the net to find all you want, many free. This example uses files downloaded from http://www.voxengo.com/impulses/ . In the example that follows, these files have been downloaded and stored in a folder that we have created and named
