How to hear reverb while recording a dry vocal in REAPER

Published September 26, 2026

Quick answer

Put the reverb on a different track from the one you are recording. REAPER writes to disk what arrives at the armed track’s record input, so a reverb sitting on a send bus is something you hear in your headphones and never something that reaches the file. Add a track, call it Monitor Verb, put ReaVerbate on it, send the vocal track to it, and raise the send until singing feels comfortable. Then play the recorded item back with that bus muted and confirm it is dry before you record the rest.

Almost nobody sings well to a completely bare headphone signal. A dry close-miked voice in isolation sounds thin, exposed and slightly wrong, and singers respond to it by pushing, going sharp, or holding back. A little reverb in the headphones fixes that in about ten seconds, and it costs nothing.

What you must not do is record it. Reverb printed onto a take is permanent. You cannot take it off later, it fights every EQ move you make afterwards, and it makes the take useless to anyone else who might mix it. So the goal is a headphone signal with reverb and a file without. In REAPER that is a routing job, not a plugin job, and it takes about two minutes to set up once.

The rule that makes this safe

REAPER records what arrives at the armed track’s record input. Everything that happens after that point, meaning sends to other tracks, other tracks’ plugins, and the master, is part of what you hear, not part of what gets written. That is why a reverb living on its own track cannot end up on your vocal file: the vocal track does not receive anything back from it.

There is one way to break that rule, and it is worth knowing so you can avoid it. REAPER can be told to record a track’s output instead of its input. In that mode, plugins on the track do reach the file. Cockos’ own troubleshooting appendix points straight at this when a recording comes back empty: “if you have selected Record Output, check the FX window for any FX that could be silencing the track’s output”. If your recordings normally come out dry, you are already recording input and you have nothing to change.

Method 1: a monitoring reverb bus

This works with any interface, including a plain two-output one or a USB mic, because it does not need a second pair of outputs. It is also the version that is hard to get wrong.

1

Add a track for the reverb

Insert a new track and name it something obvious like Monitor Verb. Leave it unarmed. This track exists only so you can hear something, which is why the name matters when you come back to the project a week later.

2

Send the vocal track to it

Open the vocal track’s routing and create a send to Monitor Verb. Keep the vocal track’s own FX chain empty. Nothing you want to avoid printing should ever sit on the armed track.

3

Put ReaVerbate on the bus

ReaVerbate ships with REAPER. Because this track carries only the reverb, turn its wet control up and its dry control down, so the bus produces reverb and nothing else. The dry voice still reaches your headphones through the vocal track itself.

Arm, monitor, and set the amount by ear

Arm the vocal track and turn record monitoring on, then raise the send level while you talk or sing until it feels comfortable. Set it by how easy it is to sing, not by how good it sounds. This is a performance aid, not a mix decision.

Use more than you would in a mix

Monitoring reverb is allowed to be obviously too much. Nothing here is permanent, so if a generous wash helps the singer commit to a line, use it. The take underneath is unaffected.

Method 2: a separate headphone mix

If your interface has more than one pair of outputs, you can go further and give the performer a mix of their own: more voice, less backing track, reverb to taste, while you listen to something completely different. Sound On Sound’s REAPER column describes this build directly. Create a track, “name it ‘Monitor Bus’ and, once more, untick Master Send”, then “create a new hardware output send from this channel to your monitoring headphones’ hardware output”. Feed that bus from the vocal track and from your backing tracks with sends, and put the reverb on the bus.

Unticking Master Send is the part people miss. Without it the headphone mix also pours into your main output and you end up hearing everything twice at odd levels.

This is worth doing if you record other people. If you only ever record yourself, Method 1 is enough and there is nothing to gain from the extra routing.

Starting settings for a monitoring reverb

ReaVerbate’s controls are documented in the Cockos effects guide: room size “specifies the size of the room whose natural reverberation you are aiming to imitate”, dampening “moderates the reverb effect to allow for the fact of items such as curtains and carpet”, initial delay “allows for a delay of a specified number of milliseconds before the reverb is produced”, plus wet, dry, stereo width and low-pass and high-pass filters. The numbers below are starting points to react to, not correct values.

ControlStarting point on a reverb busWhat it changes
WetFull, or close to itThe bus should output reverb only. Amount is set by the send.
DryOffThe dry voice already reaches you from the vocal track.
Room sizeMiddle of the rangeBigger feels grander and blurs timing cues sooner.
DampeningMiddleMore dampening makes the tail darker and less distracting.
Initial delay0–30 msA short gap keeps consonants clear before the tail arrives.
High-pass on the reverbAround 200 HzStops the tail thickening the low mids in your phones.
Low-pass on the reverbAround 8 kHzKeeps sibilance out of the tail, which is fatiguing to sing to.

Check the take is actually dry

Do this once, the first time you set it up, and then trust it. It takes twenty seconds.

  1. Record five seconds of talking.
  2. Mute the Monitor Verb track.
  3. Play the recorded item back. It should be completely dry.
Confirm it yourself, once

Routing mistakes are easy and silent. Do not take any article’s word for what your session is doing, including this one. Record five seconds, mute the bus, listen. If there is reverb on the item, the reverb is on the armed track and you are recording that track’s output rather than its input.

The latency trade-off

Monitoring through REAPER always adds a small delay, and every plugin in the monitored path adds a little more. One reverb on a bus is usually harmless, but a full chain on the armed track is not, which is another reason to keep that chain empty while tracking. If your own voice comes back late enough to be distracting, that is latency and not reverb, and the fix is a smaller audio block size. The full walkthrough is in how to fix recording latency in REAPER.

Hardware direct monitoring on an interface is the zero-latency option, but it routes the mic straight to your headphones without passing through REAPER, so there is no REAPER reverb in it. Some interfaces provide their own monitoring reverb for exactly this reason. Check your interface manual before assuming yours does not.

What this will not do

If something is not working

  1. No reverb at all. Check the send level is above zero, record monitoring is on, and the bus is not muted.
  2. Reverb on the recorded item. The reverb is on the armed track and you are recording that track’s output. Move the reverb to a bus, or switch back to recording the input.
  3. Your voice sounds doubled or flammed. Direct monitoring on the interface and REAPER monitoring are both on. Turn one of them off.
  4. Everything in the mix is drenched later. The monitoring bus is still live. Mute or delete it before you start mixing.
  5. The reverb tail is louder than the voice. The send is too hot, or the bus still has its dry control up so the voice is arriving twice.
Takeaway

Keep the armed track clean and put the reverb somewhere downstream. A send to a Monitor Verb track with ReaVerbate on it gives you a comfortable headphone signal and a dry file, and one five-second test recording proves it. If you record other people, build the same thing as a Monitor Bus with its own hardware output so the performer can have their own balance.

Recorded it dry? Here is what to put on it.

The free StudioRescue vocal chain works on the dry take you just captured. It measures the vocal and sets REAPER’s stock plugins, so you can hear a finished-sounding version in seconds. Stock plugins only, nothing to buy.
