Reverb: Create Distance Without Losing Clarity

The sound is too far away: what should change?

Begin with the synthetic voice-like phrase below. It is an original generated sound, not speech or a singer recording. Predelay is 28 ms, Decay is 1.4 seconds and Dry/Wet is 25%. The input low cut and high-frequency tail damping are enabled. This leaves several independent ways to adjust distance rather than relying on a single bigger-is-better room knob.

Compare Predelay at 3 and 28 ms while keeping Decay fixed. Predelay delays the wet path, not the original signal. Listen for the initial sound getting its own small window before the reflections arrive. A longer gap can preserve articulation without removing the tail. Push it toward 80 ms briefly: if a detached reply appears, return toward 28 ms. That audible separation may be useful, but it is no longer a subtle room cue.

Now leave Predelay alone and raise Dry/Wet to 45%. A stronger surrounding field may make the source seem less immediate. Return to 25% before shortening Decay. This comparison separates too much room level from a room that lasts too long. It also avoids mistaking a louder effect for a better effect.

Follow the end, not just the entrance

Change Decay from 1.4 to 2.8 seconds and follow a gap in the phrase. The tail should occupy more of that gap. If successive notes become hard to distinguish, shorten Decay before adding another clarity treatment. Size is not a length unit or a duplicate decay control: it changes the reflection and network delay spacing. Compare Size 70 and 140 at the original 1.4-second decay to hear a change in structure rather than simply duration.

With high shelving enabled, lower Hi Gain from 70% to 40% at Hi Freq 4.5 kHz. High-frequency energy is attenuated repeatedly inside the tail loops, so the upper tail darkens and falls away sooner. This differs from an input high cut, which limits what enters the reverb in the first place. Back off the damping if only a dull low cloud remains.

A drum room needs a different balance

The second original synthetic source has drum attacks and rests. It starts with Size 35, Decay 0.65 seconds, Predelay 8 ms and Dry/Wet 20%. Reflect is about −1.9 dB and Diffuse about −9.1 dB: these are separate levels for early reflections and the diffuse tail, not percentages of a shared total.

Raise Diffuse toward −3 dB while keeping Reflect fixed. Listen for the space filling between hits rather than just surrounding each attack. Restore the lower Diffuse level if the groove softens. Next reduce Reflect toward −6 dB. If the room loses its immediate outline even though a tail remains, bring some reflections back. A small room can still be too busy when both levels are high.

The Input Filter readout starts at 1.2 kHz and 4 octaves, placing the low edge around 300 Hz. Drag its graph handle horizontally for centre frequency or vertically for bandwidth. It reduces low energy feeding the room while leaving the dry drum body intact. Spin and Chorus modulation are off in these comparisons. Add them later if you want moving reflections or a moving tail, rather than using motion to disguise an unclear balance.

Leave Freeze off for ordinary rooms. It holds the tail feedback; Flat bypasses damping while frozen, and Cut stops new tail input while frozen. Those are sound-design behaviours, not shortcuts to a natural decay. A useful stopping point is a room you notice when removed, while the next attack still arrives clearly.
