Vocal Booth (also known as recording cabin in Vietnam) / ISO Booth are usually small to very small rooms (2-15 m2) that are isolated from the outside space to record vocals and music. solo tool to be as clean as possible.
Vocal Booth is usually processed almost completely, minimizing reflected sound so that the sound engineer can freely reproduce a private space suitable for any recording, regardless of the acoustic characteristics of the speaker. that room.
Common problems with Vocal Booth (cabin)
When stepping into a vocal booth that is not acoustically processed, you will always feel uncomfortable, suffocated, suffocated, and tinnitus. Voices sound very heavy and dark if the room is sealed with foam or very blurred because of the head reflections from the windows, the perforated wood panels are installed indiscriminately around.
This is the cumulative result of severe imbalances in room response and sustain at different frequencies. Because Vocal Booth is usually small in size, standing waves are very sparse, high intensity and fall right in the important area of vocal thickness and warmth (800-300 Hz).
As a result vocal quality, solo instruments are very bad, um, opaque, thin midrange. When you try to use Parametric EQ or Dynamic EQ to reduce the um, the vocals become too thin because this um is not only caused by too high intensity, but it is also caused by the long sustain of the um. Some specific frequencies.
The quality of the recordings you get will be completely different from raw recordings from foreign studios that have been professionally acoustically processed even though they only use equivalent equipment.
No matter how much you upgrade your microphone, mic preamp, etc., it still won’t improve much if you don’t deal with the root of the problem: Acoustics.
How to Improve Voice Recording Quality?
Unlike a large room, in a small room like the Vocal Booth, all the reflected sound does not have a positive effect on the recording. We just need to keep a little minimum so that singers and musicians don’t feel mysterious, tinnitus, unnatural.
Effective absorption of frequencies within the range of conventional vocals and solo instruments from 125Hz upwards is handled by the Clarity Panel. For further improvement of low-order standing wave absorption performance and maximum um reduction in the 80-250Hz region, combine with Clarity LF Panel in room hotspots such as 90 degree squares.
We recommend treating at least 50% of the surface area of Vocal Booth walls and ceilings for better effect.
Thanks to good design and high-quality imported materials, Clarity Panel, Clarity LF Panel offer superior performance compared to commercially available sound-absorbing foams. These foams are all made from low-quality, low-density foam that can only absorb high and mid-high frequencies. They gradually reduce the impact from 400Hz down and are almost no longer effective below 250Hz.
Many iSS customers had to peel off the entire existing sound-absorbing foam to replace it with Clarity Panel, Clarity LF; both effort and money, although after upgrading, the efficiency is greatly improved.
Capture Cleaner, Clearer Vocals with iSS Acoustics:
