What is Reverb?
Reverb (reverberation) is what happens when sound reflects off surfaces in a physical space. Clap your hands in a bathroom, then in a cathedral — that difference is reverb. It adds depth, warmth, and a sense of space to any recording.
Recording studios, music producers, podcasters, and content creators all use reverb to shape their sound. Our tool gives you six distinct spaces to choose from, with real-time preview and precise control. Add spatial movement with our 8D Audio Effect, or combine reverb with slowdown using Slowed + Reverb.
How to Add Reverb to Audio
- Upload your audio — drop an MP3, WAV, OGG, FLAC, or M4A file (up to 50 MB).
- Choose a space — pick from 6 reverb types: Small Room, Concert Hall, Cathedral, Plate, Spring, or Parking Garage. Adjust the dry/wet mix to control intensity.
- Preview and export — listen in real time, then export as a 320 kbps MP3.
Reverb Types Explained
Small Room
Tight, intimate reverb. Best for podcasts, voiceovers, and close-mic acoustic recordings.
Concert Hall
Wide, warm reverb. Great for orchestral music, cinematic scores, and full band mixes.
Cathedral
Vast, ethereal space. Perfect for ambient music, choral recordings, and epic soundscapes.
Plate
Bright, dense studio classic. The go-to for vocals, drums, and snare — used on countless hit records.
Spring
Vintage guitar-amp character. Ideal for surf rock, country, and anything that needs a retro edge.
Parking Garage
Boxy, industrial vibe. For lo-fi, experimental, and when you want something raw and urban.
Reverb vs. Slowed + Reverb
Reverb Effect (this tool) is pure reverb with no speed change. You choose the space and intensity — use it for recording, production, podcasts, or any creative project where you want to control the ambiance.
Slowed + Reverb is a lo-fi aesthetic effect that slows the track and adds reverb for a dreamy vaporwave vibe. The reverb is part of the aesthetic — the slowdown is the star.
If you want clean reverb for a podcast or mix, you're in the right place. If you want the TikTok slowed + reverb vibe, head to our Slowed + Reverb tool.
Frequently Asked Questions
What is the difference between reverb and echo?
Reverb is many reflections blending together into a continuous decay — it makes sound richer and more spatial. Echo is distinct repetitions with clear gaps between them, like shouting across a canyon. Both are reflections, but reverb is smooth and blended while echo is discrete and separated.
Which reverb space should I use?
Room for podcasts and voiceovers. Hall for music and cinematic content. Cathedral for ambient and choral soundscapes. Plate for vocals and drums (studio classic). Spring for guitar and vintage vibes. Garage for lo-fi and experimental.
What does dry/wet mix mean?
Dry is the original unprocessed sound. Wet is the reverb-only signal. At 30-40% wet, you get a natural blend where the reverb enhances without overwhelming. At 100% wet, you hear only the reverb with no original signal — useful for sound design.
Will reverb make my audio louder?
Reverb adds energy to the signal, so yes, the combined output can be slightly louder. We apply a built-in limiter (dynamics compressor) to prevent clipping and distortion, so your audio stays clean even at high wet levels.
Can I add reverb to vocals only?
This tool processes the entire audio file. To add reverb to isolated vocals, first separate vocals using a stem splitter, then process the vocal track here.
What audio formats are supported?
MP3, WAV, OGG, FLAC, M4A, AAC, and WebM. The output is always a 320 kbps MP3 file.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using the Web Audio API. Your files never leave your device.
How good is the audio processing quality?
We use the same techniques found in professional audio software: convolution reverb with real impulse responses, phase vocoder time-stretching, HRTF-based spatial audio, EBU R128 peak limiting, and LUFS loudness normalization. What you hear in the preview is exactly what you get in the export — we guarantee preview/export parity across every tool.
