Create large room ambience with a 2.4-second decay preset and editable room controls. Large Room Reverb starts with 35% wet signal, 28 ms pre-delay and a 5000 Hz damping cutoff. These are synthetic room-inspired reflections rather than a measured impulse from a particular building.

Open up a broad space

A 2.4-second tail and 35% wet blend give this preset an expansive interior impression. Sparse arrangements expose the sustained reflections more clearly than continuously dense instrumentation.

Leave the first attack visible

Twenty-eight milliseconds of pre-delay separates the direct arrival from the room response. This can keep an initial pluck or drum transient recognizable before the ambience grows.

Control low-mid buildup

Long reflections can accumulate across repeated notes. If the arrangement becomes cloudy, reducing wet level or shortening decay is often more effective than boosting the dry signal further.

Allow a generous fade-out

The rendered file includes the lingering ambience. Place the ending intentionally in an editor rather than cutting it exactly at the original source duration, which would abruptly truncate the room impression.
