Create cathedral ambience with a 6.5-second decay preset and editable room controls. Cathedral Reverb starts with 45% wet signal, 65 ms pre-delay and a 3800 Hz damping cutoff. These are synthetic room-inspired reflections rather than a measured impulse from a particular building.

Build an unusually long atmosphere

The cathedral preset starts with a 6.5-second decay and 45% wet signal. This is an intentionally spacious texture for slow passages, atmospheric sound design or dramatic transitions.

Separate direct arrival and wash

A 65 ms pre-delay allows the initial event to arrive before the extended reflection field. On short sounds this gap may become noticeable; reduce it when a more connected envelope is preferred.

Keep the tail dark

The 3800 Hz damping cutoff suppresses much of the reflected brightness. A darker tail can feel less abrasive, but it may still accumulate low-mid energy when several notes overlap.

Budget extra runtime

Every export retains the added decay after the source ends. A very short input can therefore produce a result several times longer, and repeated strong events may create a dense wash that benefits from a lower wet percentage.

Cathedral Reverb FAQs

Cathedral Reverb decodes and processes the selected audio in your browser. File contents are not sent to an audio-processing server; page analytics are described in the site privacy policy.
Cathedral Reverb saves 16-bit PCM WAV. MP3, WAV and other browser-supported inputs are decoded first; WAV output cannot restore detail lost in a compressed source.
Open Cathedral Reverb, choose your recording, adjust its settings and compare the preview before rendering a WAV download. Effect settings can be auditioned during playback.
Cathedral Reverb updates the effect during playback when you adjust a control. Use A/B to compare with the source. Render download creates a separate file using the current settings; moving a slider invalidates the previous download.
