Filter out everything above 5–10 kHz to prevent harsh sibilance from piercing through the reverb.
Why would anyone want a reverb tail that lasts 30 seconds? The application goes beyond just "making it sound big." maximum reverb sound effect
Serial reverb (Reverb A → Reverb B) with both set to 100% wet and long decays. The formula for total decay time is ( T_total = T_A + T_B ). Two 20-second reverbs yield a 40-second tail. With feedback routing, ( T_total ) approaches infinity, limited only by digital headroom. Filter out everything above 5–10 kHz to prevent
