What are Electronic Instruments?

Definition and Types

Electronic instruments can be defined as devices that produce, manipulateulate, or reproduce sound through electronic means. These instruments utilize electronic circuits and components to generate and control sound, and are distinct from acoustic instruments, which rely on mechanical or physical means to produce sound.

There are several types of electronic instruments, including synthesizers, drum machines, samplers, effect processors, and digital audio workstations (DAWs). Each type of electronic instrument has its own unique set of capabilities and functions, and is designed to serve a specific purpose in the production and manipulation of sound.

For example, synthesizers are electronic instruments that generate sound through the manipulation of various electronic signals, such as oscillators and filters. Drum machines, on the other hand, are designed to simulate the sound of drums and percussion instruments, and are often used in electronic music production. Samplers, meanwhile, allow users to record and manipulate sound samples, and are commonly used in hip-hop and electronic music production.

Effect processors, such as distortion and reverb units, are designed to alter the sound of an instrument or voice, and are commonly used in both recording and live performance settings. Digital audio workstations, or DAWs, are computer-based systems that allow users to record, edit, and mix audio recordings, and are an essential tool for many music producers and engineers.

Overall, electronic instruments offer a wide range of possibilities for sound manipulation and production, and are an essential part of modern music-making. By understanding the definition and types of electronic instruments, musicians and producers can better navigate the vast array of options available to them, and harness the power of technology to create new and innovative sounds.

Electronic vs. Acoustic Instruments

Electronic instruments are musical devices that produce sound through electronic means, as opposed to acoustic instruments that generate sound through mechanical or physical means. The key difference between electronic and acoustic instruments lies in the way they produce sound.

Electronic instruments rely on electronic circuits, amplifiers, and speakers to produce sound. These devices convert electrical signals into sound waves, which are then amplified and played through speakers. Examples of electronic instruments include synthesizers, electric guitars, and drum machines.

On the other hand, acoustic instruments produce sound through mechanical means. For example, a piano produces sound when a pianist presses down on the keys, which trigger hammers that strike strings. The vibrations from the strings are then amplified by the body of the piano and heard by the listener. Other examples of acoustic instruments include violins, cellos, and trumpets.

One of the advantages of electronic instruments is their versatility. They can be easily manipulated and controlled using various knobs, buttons, and sliders, allowing musicians to create a wide range of sounds and effects. Additionally, electronic instruments can be amplified and recorded, making them ideal for live performances and studio recordings.

However, acoustic instruments have their own unique characteristics and sound qualities that cannot be replicated by electronic instruments. The sound of an acoustic instrument is influenced by its materials, design, and construction, as well as the playing technique of the musician. As a result, many musicians prefer the warm and rich tones of acoustic instruments over the sometimes cold and artificial sounds of electronic instruments.

In summary, electronic instruments and acoustic instruments have their own unique advantages and disadvantages. While electronic instruments offer versatility and ease of manipulation, acoustic instruments provide a rich and natural sound that cannot be replicated electronically. Understanding the differences between these two types of instruments can help musicians choose the right instrument for their specific needs and preferences.

Sound Production in Electronic Instruments

Electronic instruments are designed to produce sound through the manipulation of electronic signals. These signals are generated by various components such as oscillators, amplifiers, filters, and modulators, which work together to create a wide range of sounds. In this section, we will explore the basic principles of sound production in electronic instruments and how these components work together to create music.

Oscillators

Oscillators are the heart of any electronic instrument, as they generate the electronic signals that produce sound. There are two main types of oscillators: analog and digital. Analog oscillators use a circuit to generate a continuous waveform, while digital oscillators use a mathematical algorithm to generate a waveform.

Analog oscillators typically consist of a simple circuit that includes a capacitor, resistor, and transistor. When the circuit is activated, it produces a continuous waveform that can be shaped and modulated to create different sounds. Digital oscillators, on the other hand, use a mathematical algorithm to generate a waveform based on a set of parameters.

Amplifiers

Once the oscillator has generated a signal, it needs to be amplified to produce a loud enough sound. This is where amplifiers come in. Amplifiers take the weak electrical signal from the oscillator and amplify it to a level that can drive a speaker or other output device.

There are several types of amplifiers, including solid-state amplifiers, tube amplifiers, and hybrid amplifiers. Solid-state amplifiers use transistors or integrated circuits to amplify the signal, while tube amplifiers use vacuum tubes. Hybrid amplifiers use a combination of both solid-state and tube technology.

Filters

After the signal has been amplified, it needs to be shaped and filtered to create the desired sound. This is where filters come in. Filters are devices that remove certain frequencies from the signal, allowing others to pass through.

There are several types of filters, including low-pass filters, high-pass filters, and band-pass filters. Low-pass filters allow low-frequency signals to pass through while blocking high-frequency signals, while high-pass filters do the opposite. Band-pass filters allow only a specific range of frequencies to pass through while blocking others.

Modulators

Finally, the signal can be modulated to create different effects or to control other parameters of the sound. Modulation can be achieved through various techniques, such as frequency modulation (FM), amplitude modulation (AM), and ring modulation.

FM modulation involves modulating the frequency of the carrier signal based on the amplitude of the modulating signal, while AM modulation involves modulating the amplitude of the carrier signal based on the amplitude of the modulating signal. Ring modulation involves mixing the modulating signal with the carrier signal to create a new signal that contains the frequency components of both signals.

In conclusion, sound production in electronic instruments involves the manipulation of electronic signals through oscillators, amplifiers, filters, and modulators. Understanding how these components work together is essential for anyone interested in creating music with electronic instruments.

Analog Synthesizers

Analog synthesizers are electronic instruments that generate sound by creating and manipulating electrical signals. These signals are used to control the pitch, volume, and timbre of the sound.

Generating Sound

Analog synthesizers generate sound by creating and manipulating electrical signals. These signals are used to control the pitch, volume, and timbre of the sound. The sound is created by generating a continuous electrical signal, which is then filtered and amplified to produce the desired sound.

Creating Signals

Analog synthesizers create signals using various methods, such as oscillators, envelopes, and LFOs. Oscillators generate the basic signal that forms the basis of the sound, while envelopes and LFOs shape the signal to create the desired sound.

Filtering Signals

Analog synthesizers filter signals to shape the sound. Filters remove certain frequencies from the signal, resulting in a different sound. For example, a low-pass filter removes high frequencies, resulting in a muffled sound, while a high-pass filter removes low frequencies, resulting in a bright sound.

Amplifying Signals

Analog synthesizers amplify signals to produce the desired sound volume. The signal is amplified using an amplifier, which increases the power of the signal.

Timbre

Analog synthesizers manipulate the timbre of the sound to create different sounds. Timbre refers to the unique characteristics of a sound that distinguish it from other sounds. For example, a synthesizer can create a brass sound by manipulating the timbre of the signal to mimic the sound of a brass instrument.

Overall, analog synthesizers are complex electronic instruments that generate sound by creating and manipulating electrical signals. They use various methods, such as oscillators, envelopes, LFOs, filters, and amplifiers, to create and shape the sound. Understanding the inner workings of analog synthesizers can help musicians and sound designers create a wide range of unique and creative sounds.

Digital Synthesizers

Digital synthesizers are electronic instruments that generate sound by manipulating digital signals. They are widely used in music production and are known for their ability to produce a wide range of sounds, from realistic instruments to abstract electronic textures.

Components of a Digital Synthesizer

A digital synthesizer typically consists of the following components:

  • Oscillator: The oscillator generates the basic sound waveform, which can be shaped and modified by other components.
  • Filter: The filter modifies the frequency content of the sound, creating a range of effects such as low-pass, high-pass, and band-pass filters.
  • Envelope: The envelope controls the volume of the sound over time, creating a range of dynamic effects.
  • LFO: The LFO (low-frequency oscillator) generates a modulation signal at a low frequency, which can be used to create subtle changes in the sound over time.
  • Effects: Digital synthesizers often include a range of built-in effects, such as reverb, delay, and distortion, which can be used to further shape the sound.

How Digital Synthesizers Work

Digital synthesizers work by generating and manipulating digital signals, which represent the sound waveform. The basic process involves the following steps:

  1. The oscillator generates a digital signal that represents the basic sound waveform.
  2. The signal is sent to a filter, which modifies the frequency content of the sound.
  3. The filtered signal is then sent to an envelope, which controls the volume of the sound over time.
  4. The envelope signal is then sent to an LFO, which generates a modulation signal at a low frequency.
  5. Finally, the modulated signal is sent through a range of effects, such as reverb, delay, and distortion, to further shape the sound.

Types of Digital Synthesizers

There are several types of digital synthesizers, including:

  • Subtractive synthesizers: These synthesizers generate sound by subtracting harmonics from a basic waveform.
  • Additive synthesizers: These synthesizers generate sound by adding harmonics to a basic waveform.
  • Wavetable synthesizers: These synthesizers generate sound by manipulating the waveform of a single oscillator.
  • Sampling synthesizers: These synthesizers generate sound by sampling and manipulating recorded sounds.

Hybrid Synthesizers

Hybrid synthesizers are a type of electronic instrument that combines elements of both analog and digital synthesis. These synthesizers are designed to provide the best of both worlds, offering the flexibility and precision of digital synthesis while retaining the warmth and character of analog synthesis.

Hybrid synthesizers typically have a mix of analog and digital oscillators, filters, and envelopes. The analog components are responsible for generating the raw sound, while the digital components provide control over the sound’s shape and characteristics. This combination allows for a wide range of sounds, from classic analog tones to cutting-edge digital effects.

One of the key benefits of hybrid synthesizers is their ability to offer a high degree of control over the sound. Digital controls such as LFOs, envelopes, and filters can be used to shape the sound in ways that would be difficult or impossible with analog synthesizers. This makes hybrid synthesizers ideal for creating complex and evolving sounds, as well as for experimenting with new and unconventional techniques.

Another advantage of hybrid synthesizers is their flexibility. Many hybrid synthesizers offer a range of different synthesis modes, such as granular synthesis, frequency modulation synthesis, and wavetable synthesis. This allows the user to explore a wide range of sonic possibilities and to create sounds that would be difficult or impossible with a single synthesis mode.

Despite their many advantages, hybrid synthesizers can be complex and challenging to use. They often require a good understanding of synthesis principles and techniques, as well as a willingness to experiment and explore new sounds. However, for those willing to put in the time and effort, hybrid synthesizers can be a powerful and rewarding tool for creating electronic music.

Sound Modification Techniques

Electronic instruments use a variety of techniques to modify and manipulate sound. These techniques can include filtering, equalization, compression, and reverb.

  • Filtering involves removing certain frequencies from the sound signal. This can be used to remove unwanted noise or to emphasize certain frequencies in the signal.
  • Equalization involves adjusting the balance of different frequencies in the sound signal. This can be used to boost or cut certain frequencies, depending on the desired sound.
  • Compression involves reducing the dynamic range of the sound signal. This can be used to make the sound more consistent and less dynamic.
  • Reverb involves adding ambiance to the sound signal. This can be used to create a sense of space and depth in the sound.

Each of these techniques can be used independently or in combination with one another to achieve a desired sound. Understanding how these techniques work can help you to use them effectively in your own music production.

Frequency Modulation

Frequency modulation (FM) is a method used in electronic instruments to alter the frequency of a carrier signal in response to a modulating signal. The modulating signal can be any audio signal, such as a sound wave or a voltage signal.

FM is different from amplitude modulation (AM), which alters the amplitude of the carrier signal in response to the modulating signal. In FM, the frequency of the carrier signal is varied, resulting in a signal that is rich in harmonics.

The process of FM can be described as follows:

  1. The modulating signal is mixed with the carrier signal, resulting in an FM signal.
  2. The FM signal is amplified and transmitted.
  3. The FM signal is received and demodulated, resulting in a signal that is rich in harmonics.
  4. The harmonics are filtered out, leaving the original modulating signal.

FM is used in a variety of electronic instruments, including synthesizers, radio equipment, and sound processing equipment. In a synthesizer, for example, FM can be used to create complex timbres by modulating the frequency of one oscillator with another. In radio equipment, FM is used to transmit audio signals over the airwaves. In sound processing equipment, FM can be used to create special effects, such as flanging and chorus.

Overall, frequency modulation is a powerful technique for altering the frequency of a signal in response to a modulating signal. Its ability to create complex timbres and special effects makes it an essential tool in the world of electronic music and sound processing.

Amplitude Modulation

Amplitude modulation (AM) is a method of encoding information onto a carrier wave by varying the amplitude of the base signal. The base signal can be any form of audio or video information, and the carrier wave is a high-frequency signal that is used to transmit the information over long distances.

In AM, the amplitude of the base signal is varied in proportion to the information being transmitted. This modulation is achieved by multiplying the base signal by a second signal, known as the modulating signal, which is a replica of the base signal but shifted in phase by a certain amount. The result of this multiplication is a new signal, which has a varying amplitude that corresponds to the information being transmitted.

The modulated signal is then transmitted over a long distance, typically using a radio frequency (RF) carrier wave. The RF carrier wave has a much higher frequency than the base signal, which allows it to be transmitted over long distances without significant loss of information.

When the modulated signal is received, it is demodulated to extract the original base signal. This is done by subtracting the carrier wave from the received signal, which results in a signal with a varying amplitude that corresponds to the original base signal. The demodulated signal is then processed to recover the original base signal, which can be in the form of audio or video information.

AM is a simple and effective method of transmitting information over long distances, but it has some limitations. One of the main limitations is that AM is susceptible to interference from other sources of electromagnetic radiation, such as other radio signals or power lines. This can cause the signal to become distorted or even lost altogether, which can result in poor sound quality or loss of information.

Despite these limitations, AM remains a widely used method of transmitting information over long distances, particularly in the field of radio broadcasting. With the advent of digital technology, AM has been largely replaced by other modulation techniques, such as frequency modulation (FM) and digital modulation methods, which offer improved performance and greater flexibility. However, AM remains an important part of the history of electronic communication and continues to be used in a variety of applications.

Ring Modulation

Ring modulation is a method used in electronic instruments to produce a range of complex sounds by combining two input signals. The result is a unique audio signal that is neither a simple addition nor a subtraction of the original inputs. In this section, we will delve into the details of how ring modulation works and how it is used in electronic instruments.

Principles of Ring Modulation

Ring modulation works by multiplying the two input signals together and then mixing the result with the original inputs. The product of the two input signals is called the “sum” signal, which is then mixed with the original inputs to produce the final output. This process creates a new signal that contains both the harmonic content of the original inputs and the timbre of the sum signal.

Advantages of Ring Modulation

One of the main advantages of ring modulation is that it can produce a wide range of complex sounds that would be difficult or impossible to achieve with other methods. By combining two input signals, ring modulation can create new timbres and textures that are not present in either of the original inputs. This makes it a powerful tool for electronic instrument designers and musicians who are looking to create unique and interesting sounds.

Disadvantages of Ring Modulation

One of the main disadvantages of ring modulation is that it can produce some unwanted side effects, such as aliasing and distortion. Aliasing occurs when the sum signal contains frequencies that are not present in either of the original inputs, which can lead to unwanted artifacts in the final output. Distortion can also occur when the sum signal is amplified or processed, which can alter the original timbre of the inputs.

Applications of Ring Modulation in Electronic Instruments

Ring modulation is used in a wide range of electronic instruments, including synthesizers, drum machines, and effects processors. In synthesizers, ring modulation is often used to create complex timbres and textures, such as bells, percussion, and electronic sounds. In drum machines, ring modulation is used to create unique drum sounds that are not possible with traditional drum sounds. In effects processors, ring modulation is used to create a range of unusual and unpredictable effects, such as distortion, filtering, and modulation.

In conclusion, ring modulation is a powerful and versatile method for producing complex sounds in electronic instruments. By combining two input signals, ring modulation can create new timbres and textures that are not present in either of the original inputs. While it has some disadvantages, such as aliasing and distortion, it remains a popular and widely used method in electronic instrument design and music production.

Waveform Generation

Electronic instruments rely on the generation of waveforms to produce sound. A waveform is a series of repeating peaks and troughs that define the shape of a sound wave. In electronic instruments, waveforms are generated by modulating various electrical signals to create the desired sound.

There are several methods for generating waveforms in electronic instruments, including:

  • Analog Oscillators: These use physical components such as transistors and capacitors to generate waveforms. Analog oscillators can produce a wide range of waveforms, from simple sine waves to complex waveforms with multiple harmonics.
  • Digital Oscillators: These use digital circuits to generate waveforms. Digital oscillators can produce highly accurate waveforms with precise frequency and amplitude control. They can also generate complex waveforms with a wide range of harmonics.
  • Sample-Based Oscillators: These use pre-recorded samples of sound to generate waveforms. Sample-based oscillators can produce highly realistic sounds, but they may not be as flexible as analog or digital oscillators.

Once the waveform has been generated, it is then amplified and sent through a speaker or other output device to produce sound. In some cases, the waveform may be further processed or modified using effects such as reverb, delay, and distortion to create the desired sound.

Overall, waveform generation is a crucial aspect of electronic instrument design, as it determines the quality and character of the sound produced by the instrument.

Oscillators

Electronic instruments rely on a variety of components to produce sound, and one of the most critical of these is the oscillator. An oscillator is an electronic circuit that generates a repetitive electronic signal, which is then amplified and used to produce sound. In this section, we will explore the inner workings of oscillators and how they contribute to the functioning of electronic instruments.

Types of Oscillators

There are several types of oscillators used in electronic instruments, including:

  • LFOs (Low-Frequency Oscillators): LFOs generate signals with a frequency of less than 20 Hz and are typically used to create subtle modulation effects, such as vibrato and tremolo.
  • Envelope Generators: Envelope generators produce a series of voltage pulses that are used to control the amplitude of the sound over time. They are often used to create more complex envelope shapes, such as those found in synthesizer timbres.
  • Oscillator ICs (Integrated Circuits): Oscillator ICs are small, compact circuits that generate electronic signals. They are commonly used in electronic instruments because they are relatively inexpensive and easy to integrate into other circuits.

How Oscillators Work

Oscillators work by generating a repetitive electronic signal, which is then amplified and used to produce sound. The signal generated by an oscillator is typically a sine wave, which is a smooth, curved line that oscillates around a central point. The frequency of the sine wave determines the pitch of the sound, with higher frequencies producing higher-pitched sounds and lower frequencies producing lower-pitched sounds.

The components of an oscillator include a resonant circuit, which is responsible for generating the repeating signal, and an amplifier, which amplifies the signal to produce sound. The resonant circuit typically consists of a capacitor and an inductor, which work together to create a positive feedback loop that generates the repeating signal. The amplifier then takes the signal from the resonant circuit and amplifies it to a level that is sufficient to drive a speaker or other output device.

Oscillators are essential components of many electronic instruments, including synthesizers, drum machines, and other electronic musical devices. By generating repetitive electronic signals, oscillators provide the foundation for the sound production process, allowing electronic instruments to produce a wide range of complex and intricate sounds.

Sample and Hold

Introduction to Sample and Hold

Sample and Hold is a fundamental component of electronic instruments, particularly in the context of analog synthesizers. This module plays a crucial role in shaping the sound of an instrument by enabling the control of various parameters based on a held sample of the input signal. The sample and hold circuitry work by freezing the voltage of an input signal at a specific point in time, allowing the instrument to manipulate the voltage of the held sample to create different timbres and effects.

Sample and Hold Circuitry

The sample and hold circuitry typically comprises of an operational amplifier (op-amp) configured as a comparator. The op-amp compares the input signal voltage with a reference voltage, causing the output to switch between the two states. When the input signal exceeds the reference voltage, the output switches to the reference voltage, and vice versa. This process effectively “freezes” the voltage of the input signal at the moment when the output switches to the reference voltage.

Applications in Electronic Instruments

In electronic instruments, the sample and hold circuitry enables the manipulation of various parameters based on the held sample of the input signal. For instance, in a synthesizer, the sample and hold circuitry can be used to control the envelope of a sound, where the held sample of the input signal is used to determine the attack, decay, sustain, and release (ADSR) characteristics of the sound. Additionally, the sample and hold circuitry can be used to control other parameters such as filter cutoff frequencies, LFO (low-frequency oscillator) rates, and more, thereby shaping the overall timbre and character of the sound.

Limitations and Considerations

While the sample and hold circuitry is a powerful tool for shaping the sound of electronic instruments, it does have some limitations. For instance, the sample and hold circuitry can introduce latency in the system, as there is a delay between the time when the input signal changes and the time when the output responds to the change. This latency can be problematic in certain applications, such as real-time performance, and may require compensation techniques to minimize the effect. Additionally, the sample and hold circuitry is susceptible to noise and drift, which can affect the accuracy and stability of the held sample. Proper design and implementation techniques can help mitigate these issues.

Envelope Generators

Envelope generators are an essential component of many electronic instruments, particularly synthesizers. They are responsible for controlling the volume of the sound over time, creating dynamic and expressive timbres. There are two main types of envelope generators: ADSR (Attack, Decay, Sustain, Release) and AHDSR (Attack, Decay, Sustain, Release, Hold).

Attack

The attack phase is the initial transient of the sound, which marks the beginning of the note. It is usually short and abrupt, and its duration is determined by the attack envelope. The attack envelope controls how quickly the volume of the sound rises from silence to its maximum level.

Decay

The decay phase is the portion of the sound where it gradually fades away after the initial attack. The decay envelope determines how long it takes for the sound to reach its sustain level. In some cases, the decay can be set to zero, creating a staccato effect.

Sustain

The sustain phase is the period during which the sound maintains its maximum volume. The sustain envelope determines how long the sound remains at its maximum level before entering the release phase.

Release

The release phase is the portion of the sound where it gradually returns to silence after the sustain phase. The release envelope determines how long it takes for the sound to reach complete silence. The release can be set to zero, creating a hard cutoff and a staccato effect.

In some cases, a hold phase can be added after the sustain phase. This phase maintains the sound at its maximum level for a certain duration before gradually returning to silence.

Envelope generators are used in a wide range of electronic instruments, including synthesizers, drum machines, and samplers. They are essential for creating dynamic and expressive timbres, and they provide a wide range of creative possibilities for sound designers and musicians.

Signal Processing

Electronic instruments rely heavily on signal processing to create their unique sounds and effects. Signal processing refers to the manipulation of electronic signals in order to alter their characteristics. This can include changing the frequency, amplitude, or waveform of the signal, as well as adding effects such as distortion, reverb, or delay.

There are many different techniques used in signal processing, each with its own unique characteristics and applications. Some common techniques include:

  • Amplification: Increasing the amplitude of a signal to produce a louder sound.
  • Filtering: Selectively removing certain frequencies from a signal, often used to shape the tone of a sound.
  • Modulation: Altering the frequency or amplitude of a signal in response to a modulating signal, often used to create vibrato or tremolo effects.
  • Distortion: Intentionally distorting the waveform of a signal to create a unique sound or effect.
  • Reverb: Adding a sense of space and ambiance to a sound by simulating the reflections of the signal off of surfaces in a room.
  • Delay: Adding a short delay to a signal, often used to create echo or doubling effects.

These techniques can be applied in a variety of ways, depending on the desired effect and the type of electronic instrument being used. For example, a guitarist might use distortion to create a heavy metal sound, while a synthesizer player might use filtering to shape the tone of their sounds.

Overall, signal processing is a crucial aspect of electronic instrument design and plays a major role in the unique sounds and effects that these instruments are capable of producing.

Equalization

Equalization is a technique used in electronic instruments to enhance or alter specific frequency ranges within a signal. It is often used to correct imbalances in the frequency response of a system or to create desired tonal characteristics. The goal of equalization is to boost or cut specific frequencies in an audio signal to enhance or suppress certain aspects of the sound.

Equalization can be achieved through various methods, including passive and active equalization. Passive equalization involves the use of passive components such as resistors and capacitors to alter the frequency response of a system. Active equalization, on the other hand, involves the use of active electronic components such as amplifiers and filters to achieve the desired frequency response.

Equalization can be further classified into different types based on the frequency range being affected. For example, low-frequency equalization is used to boost or cut frequencies below a certain threshold, while high-frequency equalization is used to affect frequencies above a certain threshold. Mid-frequency equalization is used to affect frequencies within a specific range.

In electronic instruments, equalization is often used to enhance or modify the tonal characteristics of the instrument. For example, a guitar may have equalization controls that allow the player to boost or cut specific frequency ranges to achieve a desired sound. Equalization can also be used to correct imbalances in the frequency response of a microphone or speaker, allowing for a more accurate representation of the sound being produced.

Overall, equalization is a powerful tool in the world of electronic instruments, allowing for precise control over the frequency response of a system. By understanding how equalization works, musicians and audio engineers can manipulate the tonal characteristics of their instruments and recordings to achieve the desired sound.

Compression

Electronic instruments use compression to reduce the dynamic range of an audio signal. Compression is achieved by reducing the volume of louder sounds and boosting the volume of quieter sounds. This is done by using a compressor, which is an electronic device that processes the audio signal.

A compressor works by measuring the level of the audio signal and comparing it to a threshold level. If the signal exceeds the threshold, the compressor reduces the level of the signal. If the signal falls below the threshold, the compressor boosts the level of the signal. The amount of compression applied is determined by a ratio, which is a value between 1:1 and infinity:1. A ratio of 1:1 means that the signal is compressed equally to the threshold, while a ratio of infinity:1 means that the signal is compressed to zero.

There are several types of compressors, including optical, VCA, and FET. Optical compressors use a light-sensitive cell to measure the level of the audio signal, while VCA compressors use a voltage-controlled amplifier to control the level of the signal.
