Hugo Zucarelli and Holophony

Recent revolutionary discoveries of the Argentine-Italian researcher Hugo Zuccarelli have extended the holographic (holographic) model to the world of acoustics.

Hugo Zucarelli is the inventor of holophonic (holophonic) sound technology.

For reasons of patent secrecy, he still has not made public the information necessary to fully understand his important discovery. In the rest of the presentation, I use the materials of the lectures that I listened to and my own experience of listening to holophonic sound during a three-day seminar in Milbra, California, in which my wife Christina and I took part.

In childhood, unfortunately, Zukarelli survived the shock when he was nearly hit by a car. His ability to accurately localize the sound of an approaching car saved his life without seeing it. This aroused his interest in the problem of how various animals localize sound in their perception. After a thorough study and analysis of the mechanisms by which animals of various species achieve accurate identification of sound sources, he came to the conclusion that existing hearing models Continue reading

Revitalizing MIDI Drums

Many may rightly argue that the great advantage of sampled, electronic drums is that they don’t force you to use ‘realistic’ rhythmic patterns or drum sounds. Most dance music, for example, is created using incredibly fast, accurate patterns and sounds that have only the most superficial relation to something that can be reproduced by hitting a stretched drum skin with a wooden drumstick. The ability to create rhythms by programming, layer by layer and step by step, of course, offers great scope for imagination and freedom from technical and sound restrictions imposed when it is necessary to play and record a real drummer.

However, it happens that the sound and feeling of a real drum part is required, and circumstances – time, place, lack of funds or lack of a drummer – force people who themselves do not play the drums to “rattle” something in the sequencer. And, although the sequencer part will never be a perfect imitation, there are many things you can do to make it seem more convincing. Continue reading

Equalizers and their application

Graphic equalizer is a multi-range corrector of the amplitude-frequency characteristics of electric sound signals. The boundaries of the full range of frequencies in which the amplitude-frequency characteristic is corrected are determined by the range of frequencies perceived by the human ear. The lower limit of this range is sound vibrations with a frequency of 20 Hz. (oscillations per second), and the upper – 20 KHz. (thousand oscillations per second).

The graphic equalizer, depending on its accuracy, determined by the width of one band, may contain a different number of ranges in which the values ​​of the amplitude-frequency characteristics are set. For example, with a bandwidth of one octave, the equalizer will contain 10 bands, with a bandwidth of 1/2 octaves – 15 bands, and Continue reading
