Audio Reverb
Add room ambience with adjustable decay, wet mix, pre-delay and high-frequency damping. A deterministic stereo convolution impulse creates dense room-like reflections. Decay extends the rendered tail; pre-delay separates the first reflection from the dry sound.

Separate dry sound and reflections
Wet mix blends the reverberated branch with the untreated recording. Low settings suggest a room behind the source; high settings make the reflected field dominate and move the source perceptually farther away.
Control the reflection envelope
Decay sets the synthetic impulse length. Pre-delay postpones its arrival by up to 150 milliseconds, allowing the initial word or drum attack to stay distinct before the ambience blooms.
Darken lingering high frequencies
Damping applies low-pass filtering to the reflected signal. Lower cutoff values soften bright hiss and sibilance in the tail without applying the same tonal cut to the dry branch.
Leave space for the ending
Offline rendering appends the selected decay and pre-delay so reflections after the last source sample are retained. Listen to the final seconds before trimming the file for a video or music arrangement.
