Updated October 2026 · Planning a home studio
Treat the room in a sensible order: first reduce the reflections near the microphone and the speaker, then address echo across the room, and only then consider bass and room modes. Soft materials near the reflection points give the biggest gain. Test after each change with a clap and a short recording.
Room treatment is the process of making a room sound more controlled, so the recording or the listening is closer to the truth. It can be expensive, and it can be done badly, with money spent on the wrong materials in the wrong places. A sensible order of priorities gives the biggest improvement first and avoids the common mistakes. This post explains that order and the reasons for it.
The advice is for home studios, which are often small and irregular. It applies to recording voice, where the room mainly affects the reflections around the microphone, and to monitoring, where the room affects what you hear from speakers.
The first priority is the first reflections: sound that bounces from nearby walls, the ceiling, the desk or the floor into the microphone shortly after the direct sound. These reflections arrive close in time to the voice and smear it, which is what most people hear as a hollow or echoey sound. Treating the points where reflections reach the microphone gives the biggest gain for the least material.
To find these points, sit or stand in the recording position, and have someone move a small mirror along the walls while you watch. Where you can see the microphone reflected, sound bounces there too. Put soft material at those points.
The second priority is the general reverberation of the room, the tail of sound that lingers after a clap. A room with hard, bare surfaces has a long tail, and soft furnishings shorten it. Add rugs, curtains, bookshelves, upholstered furniture and wall hangings across the room, not only at one point. A clap test before and after shows the change.
The third priority is low-frequency behaviour, the bass that builds up or cancels at certain points in a room. Bass problems are hard to treat with soft materials, and they are often best handled by placing speakers and listening positions carefully. Bass traps are used in some studios, but they need careful planning and are not the first step for a home recording.
Many home studios buy treatment for the wrong problem. Thick panels on a single wall may do little for the reflections that reach the microphone, while a room full of bare surfaces stays echoey. Treat the problems you can hear and measure, rather than covering walls because a plan suggests it.
Test after every change, with the same clap and the same short recording. Listen for the difference in the tail and the clarity of the voice. A change that does not make a difference is not worth the cost, and a change that helps should be kept and noted.
If you can afford only one piece, choose the one that covers the strongest reflection point near your microphone, and make sure it is thick enough to matter. A thin cover placed in the wrong spot will do less than a modest piece in the right place. Test before and after with a clap, so the purchase is backed by a result you have heard.
Treatment needs to survive ordinary life. Keep soft items away from heaters, check that blankets are not sagging into the microphone's view, and keep a simple record of where each piece sits. A room that is treated and then rearranged will drift back toward its original sound quickly.
Some surfaces should stay hard. A window, a bookcase and a wooden floor can add useful character and diffusion, and covering every surface can make the room lifeless. Treat the points that cause problems, and leave the rest alone. A room with a mix of soft and hard surfaces is usually easier to work in than a fully padded one.
Room treatment has limits. A small, irregular room will never sound like a large, purpose-built studio, and some problems cannot be solved with treatment alone. The aim is a room that sounds drier and more controlled for your work, not a perfect acoustic. Judge the result by listening.
A clap test is the simplest way to hear the room before and after treatment. The room test guide explains the method. The Vocal Checker shows noise, rumble and level problems in a recording you own, which helps you see whether the room is working for the voice. The Tunedzy Go page covers phone recordings.

The reflections near the microphone, since they affect the voice most directly.
It matters for monitoring and some rooms, but it is usually a later step for voice recording.
Use a mirror along the walls from the recording position and mark where you can see the microphone.
Compare clap tests and short recordings before and after, and listen for the difference.
