What reverb does
Reverb is the sound of a space. When you clap in a church, the echoes that blur together after the clap are reverb. A recording made in a small, dead room sounds dry and close. Adding reverb puts it in a room, making it sound bigger, softer and further away.
On AudioDrop, reverb lives on the Space knob. Turn it up to add more reverb to your audio. It is live while you play, so you can judge it in context.
Reverb is one of the most useful effects in audio. A small amount makes a recording sound finished. A large amount changes the whole mood, which is why it shows up in slowed edits, ambient music and film sound.
Because the effect is baked into the export, you get a normal audio file at the end, ready for any player, editor or video app.
When to add reverb to audio
A little space fixes a lot of recordings. Common uses:
- Give a dry vocal recorded at home a more polished feel.
- Make a phone voice memo sound less boxy.
- Add depth to acoustic guitar or piano recordings.
- Create a dreamy, washed out version of a song.
- Smooth out a spoken intro or sound effect for a video.
- Glue a karaoke vocal to the backing track.
How much reverb to use
Use this as a rough guide for the Space knob.
| Space setting | Sounds like | Good for |
|---|---|---|
| 0.1 to 0.2 | Small room | Speech, podcasts, subtle polish |
| 0.3 to 0.4 | Medium room | Vocals, acoustic instruments |
| 0.5 to 0.6 | Large hall | Ballads, ambient music |
| 0.7 and up | Huge space | Special effects, slowed edits |
Tips for natural reverb
Less is usually more. If you can clearly hear the reverb as a separate sound, it may be too much for a vocal. Turn it down until you only miss it when it is gone.
Reverb can build up low end. If the result sounds muddy, move Tone slightly toward the bright side.
For speech, keep Space low so words stay clear. For music, you can go further.
Adding reverb to a whole song affects everything at once. To put reverb on just the vocal, split the song with the stem splitter first, download the vocal stem, add reverb to it, then combine them in your editor.
Match the space to the song. A tight pop vocal wants a short room. A slow ballad or ambient track can carry a big hall. If you are unsure, start low and add a little at a time.
Limitations
You get one reverb control, not a full studio plug-in with pre-delay and decay settings. It is designed to be quick and sound good. Reverb also cannot be taken back out of a file once it is exported, so keep your original. Removing reverb from a recording that already has too much is a different problem, and this tool does not do that.
Reverb and the other four knobs
Reverb rarely works alone. The effects tool has five knobs, and a little of the others often makes the reverb sit better.
Tone shapes the brightness of everything, reverb included. Pull it slightly dark for a vintage, warm space, or slightly bright to keep a vocal crisp. Punch adds compression, which brings the dry sound forward so it does not drown in the reverb. Drive adds saturation for warmth. Bass adds low end if the recording feels thin.
| Knob | What it does | Pairs with reverb for |
|---|---|---|
| Tone | Dark low-pass to thin high-pass | Vintage or airy rooms |
| Bass | Low-shelf boost up to +12 dB | Fuller acoustic recordings |
| Drive | Saturation | Warm, analogue feel |
| Punch | Compression | Keeping vocals upfront |
| Space | Reverb | The room itself |
