Audacity Cathedral Reverb Settings

Simulating the expansive, resonant acoustics of a large cathedral requires careful configuration of Audacity’s built-in Reverb effect. Cathedrals are defined by massive stone architecture, towering ceilings, and hard surfaces that produce long decay times, high reflections, and pronounced low-end resonance. This guide details the exact parameter settings required to transform dry vocal or instrumental tracks into a cavernous, realistic cathedral space.

Recommended Reverb Parameters

To open the tool, highlight your audio track and navigate to Effect > Delay and Reverb > Reverb. Enter the following values:

• Room Size (%): 100%
  This sets the internal dimensions of the virtual room to its maximum capacity, simulating the immense physical volume of a cathedral nave.
• Pre-delay (ms): 30 to 50 ms
  Pre-delay creates a brief gap between the initial dry sound and the onset of the reverberation. A delay of 30 to 50 milliseconds mimics the time it takes for sound waves to travel to distant stone walls and bounce back.
• Reverberance (%): 85% to 90%
  Cathedrals are famous for long decay times often lasting several seconds. Setting Reverberance near 90% produces an extended tail that lingers naturally without completely washing out the source audio.
• Damping (%): 15% to 20%
  Damping controls high-frequency absorption. Because hard stone and marble absorb very little high-frequency energy, keep damping low so the higher frequencies echo brightly and persist in the tail.
• Tone Low (%): 100%
  Stone halls naturally amplify deep, resonant low frequencies. Maximizing this parameter provides the characteristic rumble and warmth found in large stone sanctuaries.
• Tone High (%): 75%
  This preserves the air and brightness of the reverberation while preventing overly harsh or metallic sibilance from dominating the mix.
• Wet Gain (dB): -1 dB to 0 dB
  Cathedral acoustics place heavy emphasis on the reflected sound. A high wet gain ensures the reverb is prominent and enveloping.
• Dry Gain (dB): -4 dB to -6 dB
  Reducing the dry signal places the sound source further back into the acoustic environment, enhancing the illusion of distance.
• Stereo Width (%): 100%
  Maximizing the stereo spread creates a wide, immersive sound field that reflects sound all around the listener.
• Wet Only: Unchecked
  Leave this box unchecked so your original performance blends with the reverb effect on the same track.

Application Tips

1. Add Room for the Tail: Cathedrals have reverb tails that can linger for three to five seconds after the sound stops. Ensure there are several seconds of silence at the end of your audio track; otherwise, the reverb will cut off abruptly. You can add silence via Generate > Silence.
2. Use Parallel Processing for Clarity: If the high wet level causes speech or intricate instrumentation to lose intelligibility, duplicate the track first (Ctrl + D). Apply the reverb to the duplicated track with Wet Only checked, then use the track gain sliders to blend the dry track and the cathedral track to taste.
