When recording vocals it's important to minimize reverberation and reduce
unwanted noise, for example spill[^1] in group performances. Professional
recording studios offer an isolation booth to deal with that. I think that a
cheap and flexible DIY[^2] approach is to build a small room out of moving boxes
and blankets. Even though there isn't the same amount of noise reduction
achieved, this solution minimizes reverberation.
## Conception
Before building a DIY vocal booth, I choose a location inside my room that
already has least reverberations. I prefer the center of a blank wall over a
corner to avoid some room modes[^3] and amplification of low frequencies.
Another aspect is to use a table turned towards the center of a wall to build
the vocal booth upon it. By this, I can place a display, keyboard and mouse
in front of the microphone stand for reading the lyrics and controlling the DAW
during performance.
## Building
The building process is easy. I fold the moving boxes and form walls around the
table. I recommend to prick small holes into the carton and use cable tie[^4]
for attachment. Don't forget to build a ceiling with blankets and leave out an
entrance to suspend a blanket as door replacement. Additionally, consider a
carton floor or use a carpet and cover any gaps with more blankets.

I arrange the microphone stand and other equipment, and try to establish a cable
layout carrying the connectors preferably outside of the box. I set up my
computer and other noisy hardware outside of the booth, ideally in another room.
## Sound check
Finally, I can set up my equipment and enter the DIY vocal booth. I place myself
in front of the microphone and test the acoustic environment. If there are still
reverberations, I try to locate the source, for example plane surfaces of
equipment, and consider covering it with blankets. For reference, I mark the
singing position inside the booth by applying tape on the floor.

## Application
You can listen to the acapella version of *WEAK* from the
[Inconvenient EP](/music/inconvenient-ep/) to get an impression of the result.
