5 Reverb Presets
Room (intimate), Hall (concert), Cathedral (massive), Plate (classic studio), and Studio (subtle vocal treatment). Each models a different acoustic environment.

Adjust reverb decay from 0.1 seconds (almost dry) to 8 seconds (endless cathedral echo). Fine-tune the sense of space.
Wet/Dry Mix
Blend the reverb effect from 0% (original audio only) to 100% (reverb only). Most vocal applications use 15-30% for natural results.

Add Professional Reverb to Audio — Free Online
This reverb generator uses convolution-based processing with synthetically generated acoustic impulse responses to add authentic reverb to any audio file. Choose from five carefully crafted presets — Room, Hall, Cathedral, Plate, and Studio — each modeling a different acoustic environment. Fine-tune the decay time from 0.1 to 8 seconds, adjust the wet/dry mix for the perfect blend, and preview the result before downloading. The output includes a natural reverb tail that extends beyond the original audio. All processing happens locally in your browser using the Web Audio API ConvolverNode.
Understanding Reverb Types — Room, Hall, Cathedral, Plate, and Studio
Each reverb preset models a different acoustic space. Room reverb (0.8s decay) simulates a small, intimate room — ideal for making dry vocals sound natural. Hall reverb (2.5s decay) recreates a concert hall with rich, expansive reflections — great for orchestral recordings and dramatic narration. Cathedral reverb (5s decay) produces massive, immersive reverberation with a very long tail — used for atmospheric effects and cinematic soundscapes. Plate reverb (1.5s decay) emulates the classic studio plate reverb with a bright, metallic character — the go-to for professional vocal recordings since the 1960s. Studio reverb (0.4s decay) adds just a subtle hint of space — perfect for spoken word, podcasts, and clean vocal production.
Frequently asked questions
What is reverb?
Reverb (reverberation) is the persistence of sound after it is produced, caused by reflections off walls, floors, and surfaces. It gives audio a sense of space — from a small room to a massive cathedral. Adding reverb to dry, studio-recorded audio makes it sound more natural and immersive.
What reverb types are available?
Five presets: Room (small, intimate space with short decay), Hall (concert hall ambience), Cathedral (massive, long decay), Plate (classic recording studio reverb with metallic character), and Studio (very subtle, professional vocal treatment that adds just a hint of space).
Can I add reverb to voice recordings?
Yes — reverb is one of the most common effects applied to vocals. A subtle Room or Studio reverb makes dry recordings sound natural and polished. A Hall reverb adds drama to narration. Cathedral reverb creates epic, atmospheric vocal effects.
