Removing the voice clips while singing
Often there is one and the same main problem with vocalists - constriction of the voice, as a result of tension of the vocal apparatus (in the neck) - external…

The advent of electronic music
Electronic music owes its birth precisely to experiments with sound. Experiments with sound, or rather with sound vibrations, were essentially closer to science than to music. But it was precisely…

Quartet what is it

In music, an ensemble consisting of four musicians or singers is called a quartet. The most widespread among them was the string quartet, consisting of two violins, viola and cello.

It appeared back in the 18th century, when amateur musicians, gathering in the evenings, spent their leisure time playing the stringed instruments. Over time, prominent musicians began to unite in quartets. Such ensembles performed at the courts of princes, in the noble rooms, and since the 19th century. – in concert philharmonic halls. Now the string quartet is one of the most common types of chamber ensemble.

However, there are still a number of varieties of quartets. By the composition of the instruments, quartets Continue reading

Acoustics Studios

To describe sound fields in acoustics, the sound pressure p, measured in Pascals (Pa), is widely used. As with electrical quantities in sound engineering, it is usually more convenient to use a logarithmic scale here. At the same time, the concept of sound pressure level (SPL) is introduced L = 20 log (p / p0), where p0 = 2 x 10-5 Pa is the sound pressure at the threshold of audibility. Very often, ultrasound is measured (or calculated) in separate frequency bands. The most widespread are octave or 1/3 octave bands with a relatively constant bandwidth. Geometrical average (below in the text for brevity, average) frequencies of these bands are regulated by international and domestic standards. A preferred range of mid frequencies for octave bands: … 125, 250, 500, … Hz; for 1/3 octave bands: … 125, 160,200, 250, … Hz. In addition to these narrow frequency bands, broadband correction is also applied, the form of which is Continue reading

Microphone for home music studio

Which musician did not encounter the problem of choosing a microphone ‘Often, when they come to the store, most of them simply don’t know what their microphone should be like. Why is a capacitor better or worse than a dynamic one, in which cases to take the “eight”, and in which cases – the usual cardioid, and so on … Eyes run wide, and as a result of the huge assortment the choice falls on anything, but not what really necessary. But actuallychoosing a  microphone is not so difficult. Walking through the windows, you should mainly pay attention to only three points – type, orientation and frequency range – in case you select a microphone for a specific instrument or voice.

Suppose you have decided on a frequency range, since today there are many universal microphones that can work well with a large number of different tones. Now let’s find out which type of microphone is most suitable for your working environment. There are two types of microphones used today – dynamic and Continue reading

What acoustics do we live in

The sound of even the most beautiful branded dynamic heads (speakers) without a case, as well as the measured technical characteristics, is absolutely not impressive … But this circumstance can only be bewildering for beginners. We all understand well that a speaker without a box is just like a string without a guitar. The role of this box is so great that they gave it their serious name – acoustic design. And only a harmonious combination of good heads with a well-built acoustic design as a result ensures a decent sound quality of the speaker system (AC). This inevitably leads to the thought of a significant influence on the sound properties of the room itself, in which the music is played.

Rooms, rooms and rooms of various sizes – our housing – turn out to be full participants in the Continue reading

Several microphones. Three to One Rule

Interference is the phenomenon of amplification of oscillations at some points in space and weakening of oscillations at other points as a result of the superposition of two or more waves arriving at these points. Wave interference is possible if the phase difference of the waves is constant in time, i.e., the waves are coherent. Wave interference is valid for waves of any nature and frequency.

When recording from several microphones, it is necessary to take care of their phasing: the signals from the microphones should not fall into the recording path in the opposite phase, since this can lead to their mutual compensation up to the complete disappearance. Without noticeable distortion of the timbre caused by interference of direct and reflected signals, the microphone can be brought closer to any reflecting surface at a distance of at least 1-1.5 m.
