The "Unnatural" section here covers a few varieties of unnatural reverb effect [0]. (I'd also recommend many of the items with the "theory" tag on this blog) In addition to those, reverbs that modulate the pitch signal are very common in music, but are physically impossible on a large scale. Most are subtle and create a detuned "thickening" sort of sound. Some will change the pitch by a whole octave or more. [1] Artificial reverbs can also have their decay rates adjusted dynamically, and can even decay "negatively" so that the reverb actually grows in volume. Any other parameter could also be adjusted in real-time (depending on the reverb) [2] [0] https://valhalladsp.com/2018/05/14/effect-o-pedia-reverb-types/ https://valhalladsp.com/2018/05/14/effect-o-pedia-reverb-typ...
