Stop Echoey Vocals: Fix Echo, Reverb and Room Sound
Learn simple ways to fix echo and reverb in your vocal recordings. Includes quick acoustic room treatment tips and how to use de-reverb post-processing tools.
You’ve got your music ready and are recording your vocals, but when you finally play it back, it sounds like you recorded in a cathedral. There’s some annoying echo that seems to be present when you play it back. Some are too obvious to ignore, some are subtle, but still the recording feels wrong in the most annoying way imaginable.
This is a common pitfall when recording your audio in a unprepared environment. The good news, however, is the culprit is most likely not your microphone, software, or even your voice. In this article, we’ll discuss and solve the causes of these audio issues, along with practical ways to condition your space and when a quick fix is needed, the de-reverb and de-echo tools that can solve the issue entirely.
Echo vs. Reverb: Why the Difference Matters
The term “echoey” is often used as an umbrella term for recordings that sound like they have too much “spaciousness.” Two common problems are usually the culprits, and often are confused because they are misused. There problems are echo and reverb, and it is important to understand the differences as they require slightly different solutions.
Echo is a trailing of sound we have all experienced at some point in a large empty room. Physically, it is when your voice travels and then hits a hard surface, and then bounces back to the hearer (in this case, the microphone). In large or highly reflective spaces (high ceilings, empty walls, or hardwood floors) it is less about that general "spaciousness" of the room and more about the physics of the objects and surfaces in your room.
Reverb is a similar but more nuanced term. Still it involves the bouncing of sound, but the difference is it is the result of numerous echoes. Echoes that occur so close together, they form a dense audible "tail," resulting in it sounding "washy." Imagine being in a building with an indoor pool or a heavily tiled locker room. This kind of sound is not just about an echo but also about how it lingers a little too long. The echoes themselves blend into what sounds like one long, continuous thing rather than discrete parts.
Both problems are from the same source, but they each have their own characteristics. How bad those reflections are will determine how you will have to go about solving them.
Why Your Room Is the Real Problem
In a properly treated studio or vocal booth, the walls will absorb those sounds, but in an average home or office environment, those bounces have nothing to stop them from going straight back to your microphone. Without sound absorption strategies for your environment, you are left to just deal with it.
The causes of these types of audio distortions are typically hard and flat surfaces. An environment with things like hardwood floors, large windows, and walls facing each other too closely. All of them allow sound to bounce and travel with little resistance. Sometimes the human ear doesn’t catch this as noticable, but a microphone will.
This is why a walk-in closet piled up with clothes can often lead to a cleaner recording. Soft, irregular surfaces are great at absorbing and scattering sound so the chance of those annoying bounces getting back to your microphone is less likely.
How to Treat Your Recording Space (Without New Equipment)
That being said, you need to be realistic about what you can do to improve your environment, so here are a few things below you can do.
First, it is worth noting that buying a better microphone won’t help. A better quality mic will capture everything even more accurately. So, if your room has an echo problem, a better microphone will only make that worse.
Second, getting closer to the microphone can help sometimes since your direct voice overpowers the sound of the room. However, the trade-off is your voice will likely sound unnaturally "boomy." Additionally, if you are not using a pop filter, then you also risk picking up every lip smack or tongue movement. This is to say, you may create new and different problems with this solution alone. Unless you’re intentionally recording ASMR, that’s probably not what you want in your recordings.
Some creators hang moving blankets or acoustic foam panels on the walls around their recording equipment so that they absorb more sound. This can be pretty effective without too much investment, and you can easily find “acoustic foam panels” online with sites like Amazon or even in your local Walmart.
None of these strategies are a magic eraser, though. Most home setups will probably still have to contend with some environmental noise, but when that happens, simple online post-processing tools can fix that.
How to Fix Echo and Reverb in Post-Processing
If the take is already captured or your environment remains uncooperative, turning to de-echo and de-reverb tools is the most efficient way to handle this.
De-echo specifically targets those distinct, delayed bounces, stripping away the repetitive sounds without degrading the source audio. Meanwhile, de-reverb works on the dense "tail" of the sound, refining the audio by pulling your voice more forward. When used correctly, it can turn a washy, "echoey" recording into something that comes off more like it was made in a personal studio.
Online tools like Lalals de-echo and de-reverb handle this without requiring you to learn complicated software or dig through Reddit threads for the right options. These tools target music composers who want professional results without the hassle of complicated software.
The process is very simple, as you only need to upload your audio and let the platform do all the work.
One Honest Caveat
Post-processing does have its own limits. These tools work well for mild to moderate echo and reverb, but if a recording has heavy reflection problems, some of that sound gets very hard to remove completely without also hindering the quality of the voice itself.
The fix for that is almost always to re-record in a somewhat better environment. Post-processing tools can be very helpful, but they often work better as polish on a decent recording than as a rescue operation for a bad one.
If your recording is somewhat decent and you have minimized as much as you can, de-echo and de-reverb will help you cross that finish line to perfection.
Don’t Waste Money on Equipment
It is a common trap to chase high-end equipment before addressing the most obvious variable in the equation (your room). If you take the time to condition your environment (even if it is imperfect), your results will improve significantly.
The best path forward is to fix what you can. Soften the walls and surfaces around you, and be deliberate about where you record. If you do that the best you can, then post-processing tools are a perfect refinement step for that perfectly polished recording.
