Acoustic vocal booth design for only 450 euros

If you are interested in having a good room to record voices in a professional way, we offer tailor-made solutions, ideal especially for those who do not have large spaces or who do not want to spend excessive amounts of money to treat a larger room. A vocal booth usually has a size of 3-5 sq m. We create vocal booth in various forms in order to better optimize the spaces of your environment. The standard sizes are rectangular, but we can design triangular, hexagonal or booths in the most suitable shapes for your environment. If you consider that useless accessories such as the reflexion filter cost 260 euros, you will have all our support to get a vocal booth like those that are used to record artists from all over the world in the most renowned recording studios at an affordable cost. A vocal booth is also suitable for recording musical instruments such as guitar, bass, etc.

Why design a vocal booth with us?

The voice is the most important tool in a song, so you have to make the most of it. A voice can take on a different character based on the choice of the audio chain (preamp, microphone, compressor, eq, etc.) but what affects the most is precisely the type of acoustic treatment. There are various schools of thought about acoustic treatment, some are mainly based on acoustic diffusion, others only on absorption, others on a mix of the two schools of thought, all of this can be done with different techniques, different materials, thicknesses and densities, as well as a different target of the reverberation decay time, as you can see the variations are many while following the same school of thought. Our acoustic approach is based on that of some of the most famous acoustic engineers who have created rooms in which the voices of many international artists have been filmed. If you have good ears you can see that most Italian voices sound different from the voices recorded in American or British studios, it's just a matter of taste, do you prefer a neutral and crystalline voice or full-bodied and detailed? We like to obtain very characteristic voices where detail and body should not be missing.

Preconditions


If you need to record your voice professionally, it will not be enough to buy thousands of euro microphones such as a neuman u87, u47, Akg C12vr, Brauner or high-end preamps such as those of Focusrite, Avalon, Millennia, Manley, Amek, Neve or SSL, it won't even be enough to use compressors or hardware equalizers !.

Why don't you get professional vocal shots?

We often contact users who have super professional audio chains but who are unable to obtain satisfactory results, some think that there are very sophisticated ways to treat a voice, in reality the sound of a good voice recording is closely related to the room in which you are records.

Is it possible to get good results with portable vocal acoustic filters?

If you don't know, there are commercial voice filters that have the aim of treating the area around the microphone acoustically, among the famous microphone filters we find the Se electronics reflexion filter / space, Haston halo, Primacoustic VoxGuard, Auralex MudGuard and Kaotica Eyeball. Some of these work better, others worse but none of them will allow you to get professional results in a bad room. These filters can only be used for corrective use in rooms that already sound good. The reason why they cannot work is because they are too thin to work on low frequencies, generally they can make small improvements from 1000 hz upwards, moreover to treat a small or medium-sized vocal room you have to treat all the walls of the room not just the area behind the microphone. Based on this, an interesting filter was invented, the Isovox Mobile Vocal Booth V2 that works better than the other filters listed above but still does not allow you to obtain professional vocal shots, it is a compromise to obtain acceptable recordings considering that it costs just under 1000 euros. Isovox makes the sound of voice recordings too dead,

Is it enough to treat a room with DIY acoustic panels?

Many non-professional recording studios resort to DIY, there are those who use egg cartons or those who use pyramidal sound-absorbing panels. In both solutions, good results will not be obtained, on the contrary, the pyramidal panels could worsen the microphone recording as they mainly absorb the medium-high frequencies making the frequency response of the room unbalanced.

Is it enough to buy panels from companies with acoustic certification?

On the web you can find various manufacturers of acoustic panels that offer free acoustic advice and absorption certifications, among these we find Vicoustic, Gikacoustics, Primacoustic, Hofa, Auralex, etc. The panels of these companies have been tested in laboratories, so they have graphs that show the sound absorption coefficient, but despite this their panels will not be enough to professionally treat a vocal booth (vocal room) or a shooting room for instruments as in the case of a room smaller than 40 m2 it is necessary to cover all surfaces except the floor with 20-30 cm thickness of sound-absorbing material. For reasons of size and practicality, there are no acoustic panel manufacturers who make panels of this size, therefore acoustic walls must be created. The panels of these companies can help improve the frequency response of a room used as a control room as compared to a vocal recording room, it does not need to cover all the walls, considering that they will allow only good compromises to be obtained as they are not they will be able to obtain super linear performances within a range of 6 db in the frequency response of the room.

How to treat a room to record voices?

If you have a classic room of about 15-25 square meters, you will need to proceed with the treatment of all the surfaces of the room through acoustic walls 20-30 cm thick, filled with absorbent materials with the right densities, many use rock or glass wool with density from 50 kg or more worsening the situation because when the density increases in proportion to a thickness of 20 cm, the absorption on the low frequencies decreases. We use two types of density tested in order to obtain a balanced absorption over the entire frequency range.

Once this first step has been completed, the room may sound dead, therefore after making acoustic measurements we will add wooden slats of different widths calculated in order to precisely add the frequencies that have been excessively absorbed, but be careful, it will not be enough to add some random wooden slats, avoid do it yourself for this operation, acoustics is science and we have precise criteria for this.

Is it better to treat the whole room or create a vocal booth?

Treating the whole room to get good voice recordings is very expensive as it will be necessary to buy a lot of rock wool, wood, etc., moreover this will lead to its shrinkage. An interesting solution is the creation of a vocal booth, it is a vocal booth with an area of at least 3 square meters. In the forums there is a lot of wrong information about the vocal booth, we often hear that they have a canned sound, this is true but only in case they are not treated properly.
