Schematic Diagram

Reverb.it is specialized in computing diffuse reflections of rooms. It consists, roughly speaking, of five components: 1) an output mixer where the dry input signal and the reverberated signal is mixed and the output gain is adjusted, 2) an equalizer consisting of a low shelf and a high shelf filter, 3) a delay unit which introduces a variable predelay of the reverberated signal, 4) a splitter that separates the delayed signal into up to three frequency bands, 5) and finally (and most importantly) three reverberators generating diffuse reflections. The block diagram of Reverb.it is shown below:

Let us take a closer look at the diagram. The input channels are mixed into a single mono signal and fed into two shelving filters. Each shelving filter has adjustable midpoint frequency and an adjustable gain of -24 ... +12 dB. These filters can be used to set the basic spectral balance of the reverb. Behind the filters, a delay unit introduces a predelay of up to 160 ms. What follows is a unit that splits the signal into three separate frequency bands with variable crossover frequencies. Each frequency band is then sent into a separate stereo reverberation device, generating diffuse reflections with variable density and quality. Finally, the three stereo reverberator outputs are added and mixed with the original dry signal. The level knob in the output stage lets you reduce output level just in case things get too loud.
