The nature of the sound of tube amplifiers

Exciter (from the English Exciter), also called harmonic exciter (harmonic exciter), psychoacoustic processor (psychoacoustic processor), enhancer (enhancer) and acoustic exciter (aural exciter) – this is a processing device used for the harmonious synthesis of high-frequency signals, using thin harmonic distortion.

This harmonic synthesis consists in creating higher harmonics based on lower signal frequencies. Typically, noise is present in different frequency bands in unequal amounts, and harmonics obtained from a clean frequency band will be clearer. Less commonly, exciters (enhancers) are used to synthesize low-frequency harmonics in order to simulate deep bass.

Initially, exciters were made on the basis of tube amplifiers, but now they exist in the form of digital processors.

Exciters and enhancers are used to change the tonal qualities of sound. But, unlike the equalizer, which Continue reading

What is maximizer and why

Maximizer (digital peak limiter) is a dynamic processing device that increases the level of the audio signal during mastering. Sometimes other types of devices are called maximizers, for example, psychoacoustic processing such as BBE Sonic Maximizer – we will not consider them here. We will get acquainted with the principles of operation of dynamic processing devices and compare with each other some popular models of software maximizers.

Volume and levels

The sound volume depends not only on the sound level (or sound pressure), but also on its spectral-temporal composition. If the frequency balance of the phonogram is already determined and it is Continue reading

Sound effects

Let’s dwell on the consideration of those manipulations with sound that allow you to achieve the appearance of effects such as, for example, echo, reverb, etc. There are various ways of transforming sound (amplitude, frequency, etc.). Based on these transformations, sound effects are realized. Basically, the goal of sound processing is to give the existing sound some new qualities or eliminate undesirable ones. Sound effects refer to those sound transformations that give the sound new forms or completely change the sound information.

The hardware implementation of sound effects is found in digital signal processors (DSPs). Any more or less decent MIDI synthesizer has a built-in effect processor of one or another complexity (the effect processor is one or more DSPs). Complex effect processors “know how” to apply several different effects to the sound signal at once, moreover, separately for each channel, allowing you to adjust the parameters of the effects in real time. However, the cost of such effect processors is extremely high (like the cost of any other high-performance microprocessor), so professional DSPs are installed only on high-quality musical equipment. On more or less cheap sound cards, DSP is often installed with a simplified set of features: applying one or more effects to all Continue reading

Why do I need an arrangement

There are several interpretations of the word “arrangement”. In the Soviet methodology, it meant transferring finished music to another performing staff, for example, from a piano to a four-voice choir, from a vocal duet to a trombone duet with balalaika. When the subject of instrumentation begins at a music school, students begin to get confused – how is the arrangement different from instrumentation. Another interpretation is variation, i.e. approximately the same changes as when composing variations: changes in tempo, rhythm, size, style. At the same time, significant changes are often made to the author’s melody.

The arrangement can go so far that it completely replaces the original music with another one that is not Continue reading

Vocoders: practice and assortment

Vocoder (English voice coder – voice encoder) – a speech synthesis device based on an arbitrary signal with a rich spectrum. Initially, vocoders were developed in order to save the frequency resources of the radio link of a communication system for transmitting voice messages. Savings are achieved due to the fact that instead of the actual speech signal only the values ​​of its certain parameters are transmitted, which on the receiving side control the speech synthesizer. The speech synthesizer is based on three elements: a tone generator for forming vowels, a noise generator for forming consonants, and a system of formant filters to recreate the individual characteristics of the voice. After all the transformations, the human voice becomes like the voice of a robot, which is quite tolerable for communications and interesting for the music industry.

Vocoder as an unusual effect was adopted by electronic musicians and subsequently became a full- Continue reading
