Humanity has entered an amazing era of total growth in entertainment and media. Experts predict that the global industry will reach $2.5 trillion by 2023.
Leading trends in the area include:
- digitalization;
- increasing user consumption through mobile devices;
- merger of business lines at key points of customer bases;
- vertical integration.
The list of radio stations, recording studios, broadcasting centers is updated daily. The quality of sound transmission is categorically different from the previous century. In addition to processing and storing data, acoustic systems play an important role, standing at the forefront of receiving sound vibrations.
Studio microphones
Not only professional radio and television studios, sound recording companies, but also home amateur centers are equipped with modern systems.
The main task of a microphone is to convert an acoustic wave into an electronic signal. The main role is assigned to the membrane 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
A focus on functional compliance with the task and conditions of use is a priority. What criteria should be followed or are recommendations sufficient?
Frequency range
The characteristic determines the width of the frequencies that the microphone can pick up. The volume of sound and expressiveness depends on the breadth of the range. For 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 generally accepted that the soft sound is provided by tube preamps.To obtain a transparent sound, a semiconductor type of acoustics is more suitable.
Maximum sound pressure
At a certain level of pressure, 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 pain anatomical perception. When the ear is already hurting from the playback power, the microphone continues to work without overload. However, not all condenser microphones can handle drum recordings.
Cardioid model
All over the world there is a wave of amateur and professional vocal recordings of various formats. The cardioid will allow you to exclude extraneous noise, limit the sound coverage, cut off the lower threshold, and give out 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 capable of adding expressiveness, enriching the voice with a third-party "charm", as a rule, has a hybrid circuit with an external amplifier.
Errors when choosing
The opinion that it is possible to hide flaws in voice and tonality through studio processing is very doubtful. Of course, the "figure" will emphasize the dignity and enhance the effect. However, the model of the microphone will not affect the talent of the performance.
