String Instruments

String instruments produce sounds when their string(s) vibrate. They exist in all music cultures. And all have three main parts: the body, the neck, and the head. The bodies are often made of different kinds of wood, while the strings are often made of nylon, steel, or gut. There are two main techniques to produce…

Percussion Instruments

Percussion instruments are instruments that produce sounds by striking, hitting, scraping, or shaking. Every orchestra has a percussion section. This includes instruments such as snare drum, bass drum, cymbals, triangles, and tambourines, among the other non-percussion instruments. The key is that all percussion instruments keep a certain rhythm. In addition, they make specific sounds and…

Keyboard Instruments

Broadly speaking, keyboard instruments are musical instruments you play with a keyboard. The most popular examples are pianos, organs, and electronic keyboards, such as synthesizers and digital pianos. They also include celestas and carillons, for instance. The term keyboard is often describes keyboard-style synthesizers. And the player can use the keyboard itself to control several…

Harmonizers

Harmonizers are a type of pitch shifter that can merge the shifted pitch with the original pitch. By doing this, the player is able to create a two or more note harmonies. When used for digital recording, you achieve pitch shifting through digital signal processing. The first digital processors could pitch only in post-production, but…

Octaver: an Audio Effect

An octaver audio effect is a simple form of a harmonizer that creates harmonies from more than two notes. It operates by shifting the original version either one octave up or one octave down. In other words, this effect mixes the input signal with a synthesized one. The synthesized octave signal comes from either by…

Arpeggiators

Arpeggiators are extremely simple real-time sequencers that require a chord as an input. They are a type of broken chord in which the notes that compose it are played or sung in an ascending or descending order. An arpeggiator does not play or sing its notes at the same time. Yet, listeners are able to…

Optical Compressors

Optical compressors, also known as opto-compressors, are a dynamic range attenuator that have a transducer. A light source in a photosensitive cell controls the gain reduction in an Opto-compressor, as it transforms energy from one form to another. These optical compressors serve to process and audio signal. In simple terms, they work by transforming the…

Tube Compressors

Tube compressors are compressors that rely on tubes to tame the dynamic range of your audio signal. But before delving into an explanation, we must first understand the involvement of tubes themselves. The Tubes in Tube Compressors The main job of tubes in audio equipment is to amplify electricity. The first vacuum tubes were used…

VCA Compressors

Voltage-controlled amplifiers, also known as VCA compressors, have the fastest response of the attack and release parameters. VCAs usually have less coloration than optical or tube compressors. In addition, they are fairly similar to digital tape in terms of recording. This type of compressors are cheaper than tube or optical compressors. Voltage-controlled amps provide the…

FET Compressors

Field effect transistors, also known as FET, are a type of dynamic audio effect. FET compressors are devices from the family of dynamic audio effects. Their design maintains more transients, which adds an extra punch in contrast to the variable. These extra punches are known as mu and VCA compressors. Generally, the slowest attack time…
