Convolution Reverb

Parameters

Predelay — Time in ms between the dry signal and the start of the convolution tail, 0–500. Small values (0–20 ms) feel natural; medium (30–80 ms) push the reverb behind the source for clarity; large values approach a slapback-then-tail effect.

Mix — Equal-power blend between dry (0) and the convolved signal (1). Typically use values in the 0.2–0.5 range for natural-feeling reverb; higher values push the source into the space.

Output Gain — Output level in dB, −40 to +12. Convolution can produce hot output when using long impulses; this lets you bring the level back into shape.

Additional controls

Ir Source — How the impulse response is loaded:

• Built-in — uses one of the bundled IR types (selected via the second radio: Room, Hall, Plate, Chamber).
• Custom File — loads a user-supplied WAV impulse response from disk via the Browse button.

Use Built-in for fast setup with reliable presets; Custom for matching specific spaces or using third-party IR libraries.

Builtin Ir Type — When ir_source is Built-in:

• Room — small, intimate space; fast decay (0.3–0.8 s).
• Hall — large concert/orchestral space; slow, smooth decay (1.5–4 s).
• Plate — vintage plate-reverb style; bright, dense, characterful tail.
• Chamber — mid-sized acoustic chamber; balanced between Room and Hall.

Ir File Path — When ir_source is Custom File: the absolute path to a WAV file used as the impulse response. Drag-and-drop or Browse to pick. Path is saved with the graph but doesn’t travel between machines (similar to LoadAudio).

About Convolution Reverb

Convolution reverb works by recording the impulse response (IR) of a real space (or a piece of gear), then mathematically applying that IR to your audio — the result sounds like your audio was played in that space. Unlike algorithmic reverbs (Native, Dattorro, Spring) which simulate spaces with delay-line networks, convolution reverbs use recorded responses and reproduce them faithfully. Use it for: matching specific real spaces, gear-modeled reverbs (vintage plate units, EMT reverbs, classic spring tanks), or precise studio-style ambience. Trade-off: convolution can’t easily change the space’s character (you’d need a different IR), where algorithmic reverbs offer more parameter flexibility.
