Humanity has entered an amazing era of total growth in entertainment and media. The forecasts of experts say that the volume of the global industry will be $ 2.5 trillion by 2023.
The leading trends in the region include:
- digitalization;
- growing user consumption through mobile devices;
- merging of business lines at key points of client bases;
- vertical integration.
The list of radio stations, recording studios, TV broadcasting centers is updated daily. The quality of sound transmission is completely different from the previous century. In addition to processing and storing data, acoustic systems play an important role in the vanguard of receiving sound vibrations.
Studio microphones
Modern systems are installed not only in professional radio and television studios, recording companies, but also in home and amateur centers.
The main task of a microphone is to convert an acoustic wave into an electronic signal. The main role is assigned to the membrane, which is responsible for the perception of sound air vibrations. An electrical vibration is transmitted from the membrane, which forms a signal.
Studio acoustics differ in the type of transducer and can be:
- condenser;
- tape;
- dynamic;
- electret.
How to choose the right microphone
The focus on functional compliance with the task and conditions of use is a priority. What criteria should be adhered to, or are the recommendations enough?
Frequency range
The characteristic determines the width of frequencies that the microphone can pick up. The volume of sound and expression depends on the width of the range. In capacitor models, the boundaries are determined by the perception of the human ear - from 20 Hz to 20 kHz. Dynamic type equipment has a narrower range.
Preamplifier
The following circuit technologies are distinguished:
- lamp;
- transistor;
- transformer;
- hybrid.
It is believed that soft sound is provided by tube preamplifiers. To obtain a transparent sound, a semiconductor type of acoustics is more suitable.
Maximum sound pressure
At a certain pressure level, the diaphragm begins to distort the sound. The maximum characteristic indicates the ability of the equipment to withstand the load. Manufacturers of our time set the threshold at the level of painful anatomical perception. When the ear is already hurting from the playback power, the microphone continues to work without overloading. However, not all condenser microphones can handle drum recordings.
Cardioid model
There is a wave of amateur and professional vocal recordings all over the world in all kinds of formats. The cardioid will allow you to exclude extraneous noise, limit the sound coverage, cut the lower threshold, and give the optimal sound of the voice.
If we are talking about screaming and growling, then it is worth stopping at the dynamic version of the equipment, which more effectively conveys aggressive vocals.
Hybrid type
Acoustics that can add expressiveness, enrich the voice with a third-party "charm", as a rule, have a hybrid circuit with an external amplifier.
Selection errors
The opinion that it is possible to hide flaws in the voice and tonality by studio processing is highly doubtful. Undoubtedly, “digital” will emphasize the advantages and enhance the effect. However, the mic model will not affect the performance talent.

Dynamic microphones
The transducer in this class of acoustics is not a plate, but a diaphragm attached to a rigidly fixed coil of a thin wire. When exposed to sound waves, the diaphragm oscillates, the movement of the coil in a magnetic field perturbs the space and creates an electrical signal. The basis of the process is the release of tension from the coil created by an external stimulus.
