How Does a Synthesizer Create Sound?

Oscillators

Oscillators are the core component of a synthesizer that generate sound. They produce a continuous electrical signal that is then amplified and shaped by other components to create a specific tone. The most common type of oscillator used in synthesizers is the voltage-controlled oscillator (VCO), which uses a feedback loop to control the voltage of the signal it produces. Other types of oscillators include the envelope generator, which is used to shape the volume of a sound over time, and the low-frequency oscillator (LFO), which generates a low-frequency signal that can be used to modulate other aspects of the sound. The specific characteristics of the oscillator, such as its frequency and waveform, can be controlled by the user to create a wide range of sounds.

Waveforms

Waveforms are the foundation of synthesizer sound creation. They are mathematical representations of sound that determine the characteristics of the sound that is generated. Waveforms are created by plotting the amplitude (loudness) of a sound over time.

There are several types of waveforms used in synthesizers, including:

• Sine Wave: A sine wave is a smooth, continuous waveform that produces a pure tone. It is often used as a building block for creating more complex sounds.
• Square Wave: A square wave is a waveform that consists of a series of sharp, rectangular pulses. It produces a harsh, edgy sound and is often used in electronic music to create bass or percussion sounds.
• Triangle Wave: A triangle wave is a waveform that starts as a sine wave and gradually transitions into a square wave. It produces a unique, slightly muffled sound that is often used in electronic music.
• Noise Wave: A noise wave is a waveform that consists of a random, unpredictable pattern of sound. It produces a raw, industrial sound and is often used in electronic music to create percussion or bass sounds.

In addition to these basic waveforms, synthesizers can also generate more complex waveforms by combining multiple waveforms together. This is known as waveform synthesis and allows for the creation of a wide range of unique sounds.

Waveforms are a fundamental aspect of synthesizer sound creation and understanding how they work is essential for creating electronic music. By experimenting with different waveforms and modifying their characteristics, synthesizer users can create a wide range of sounds and textures to use in their music.

Filtering and Modulation

Synthesizers use a variety of techniques to create sound, with filtering and modulation being two of the most important. In this section, we will explore these techniques in detail and see how they contribute to the overall sound of a synthesizer.

Filtering

Filtering is the process of removing certain frequencies from a sound, while allowing others to pass through. This is done using a filter, which can be adjusted to remove certain frequencies. There are several types of filters used in synthesizers, including low-pass, high-pass, and band-pass filters.

Low-pass filters allow low frequencies to pass through while attenutating (reducing the volume of) high frequencies. This creates a “mellow” sound, often associated with bass tones.

High-pass filters do the opposite, allowing high frequencies to pass through while attenuating low frequencies. This creates a “bright” sound, often associated with treble tones.

Band-pass filters allow a specific range of frequencies to pass through, while attenuating frequencies outside of that range. This creates a “peaked” sound, often associated with lead tones.

Modulation

Modulation is the process of changing a signal in some way. In synthesizers, modulation is used to create movement and change in the sound. There are several types of modulation used in synthesizers, including amplitude modulation, frequency modulation, and filter modulation.

Amplitude modulation (AM) is the process of changing the amplitude (volume) of a signal in response to another signal. This creates a “vibrato” effect, where the volume of the sound is repeatedly increased and decreased.

Frequency modulation (FM) is the process of changing the frequency of a signal in response to another signal. This creates a “harmonic” effect, where the pitch of the sound is repeatedly increased and decreased.

Filter modulation is the process of using the output of one oscillator to control the cutoff frequency of another oscillator. This creates a “feedback” effect, where the sound is constantly changing in response to itself.

Overall, filtering and modulation are essential techniques used in synthesizers to create a wide range of sounds. By understanding these techniques, you can begin to create your own electronic music using a synthesizer.

The Basics of Synthesizer Architecture

Voltage Control

Voltage control is a fundamental aspect of synthesizer architecture that enables the synthesizer to manipulate the sound by changing the voltage levels of various components. The basic principle behind voltage control is that the synthesizer can control the amplitude, frequency, and other parameters of a sound wave by applying a voltage to different components.

The voltage control circuitry is made up of various components, including voltage-controlled oscillators (VCOs), voltage-controlled filters (VCFs), and voltage-controlled amplifiers (VCAs). These components are designed to respond to changes in voltage, which in turn, affect the sound wave’s properties.

For example, a VCO can be controlled by a voltage signal, which alters the frequency of the sound wave it generates. Similarly, a VCF can be controlled by a voltage signal, which changes the cutoff frequency of the filter, affecting the tone of the sound wave.

In addition to these components, there are also voltage-controlled envelope generators (VCEs), which control the volume or amplitude of the sound wave over time. VCEs can be used to create complex and dynamic sounds by applying different voltage signals to the different stages of the envelope.

Overall, voltage control is a crucial aspect of synthesizer architecture, allowing for the creation of a wide range of sounds and effects. By understanding how voltage control works, musicians and sound designers can gain a deeper understanding of the technology behind electronic music creation and unlock new creative possibilities.

Auxiliary Modulation

Auxiliary modulation is a crucial aspect of synthesizer architecture that allows for the manipulation of various parameters within the synthesizer, thereby enabling the creation of a wide range of sounds. In essence, it is a form of modulation that does not involve the direct control of the oscillators or the filter section of the synthesizer. Instead, it is focused on the manipulation of other parameters, such as envelopes, LFOs, and other modulation sources.

There are several types of auxiliary modulation, each with its own unique characteristics and functions. Some of the most common types include:

• Envelope modulation: This type of modulation involves the use of an envelope to modulate a parameter, such as the amplitude or filter cutoff. Envelopes can be shaped in various ways, such as ADSR (Attack, Decay, Sustain, Release) or AR (Attack, Release), and can be used to create a wide range of dynamic effects.
• LFO (Low-Frequency Oscillator) modulation: LFOs are modulation sources that produce a low-frequency oscillation, typically in the range of a few Hz to a few KHz. They can be used to modulate various parameters, such as the amplitude, filter cutoff, or effect settings, and can create subtle and complex changes in the sound over time.
• Sample-and-hold modulation: This type of modulation involves the use of a sample-and-hold circuit to capture the value of a parameter at a specific moment in time, and then hold that value for a specified duration. It can be used to create various effects, such as tremolo or vibrato.
• Ring modulation: This type of modulation involves the multiplication of two signals to create a new signal, which can be used to modulate a parameter. It can create complex and unpredictable effects, and is often used in experimental electronic music.

In addition to these types of modulation, there are many other techniques and methods that can be used to manipulate and shape sound within a synthesizer. Understanding the basics of auxiliary modulation is an essential part of mastering the art of electronic music creation.

Envelopes

Envelopes are a fundamental component of synthesizer architecture. They are responsible for controlling the amplitude or volume of a sound over time. In other words, they determine how long a sound should last and how loud it should be during that time.

There are two main types of envelopes: ADSR and AHDSR.

ADSR Envelope

The ADSR envelope is the most common type of envelope found in synthesizers. It stands for Attack, Decay, Sustain, and Release.

• Attack: This is the initial burst of sound that occurs when a key is pressed or a note is triggered. The attack phase is where the sound rises from silence to its maximum volume.
• Decay: This is the process of the sound gradually settling down to a steady-state after the attack phase. In other words, it is the time it takes for the sound to reach its sustain level.
• Sustain: This is the level at which the sound remains constant during the sustain phase. It is the volume at which the sound holds for as long as the key is held down.
• Release: This is the final stage of the envelope, where the sound gradually fades away after the key is released.

AHDSR Envelope

The AHDSR envelope is an extension of the ADSR envelope. The added “H” stands for Hold.

• Hold: This is the phase between the release and decay stages. In this phase, the sound remains at its sustain level even after the key is released. This allows the sound to continue playing even if the key is released before the decay stage begins.

Envelopes are essential to the creation of complex and dynamic sounds in synthesizers. They allow for the creation of realistic instrument emulations, as well as unique and evolving soundscapes. Understanding envelopes and their properties is a crucial step in mastering synthesis and electronic music creation.

Understanding the Components of a Synthesizer

Oscillator

An oscillator is a fundamental component of a synthesizer, responsible for generating and controlling the primary sound wave that is used to create a wide range of electronic music. In essence, an oscillator is a circuit that generates a repetitive waveform, which can be manipulated and modified in various ways to produce a diverse array of sounds.

There are two main types of oscillators used in synthesizers: analog and digital. Analog oscillators use physical components, such as transistors and capacitors, to generate and shape sound waves. Digital oscillators, on the other hand, use mathematical algorithms to create sound waves.

Analog oscillators typically consist of a single oscillator circuit, which produces a sine wave or a pulse wave. By combining multiple oscillator circuits, it is possible to create more complex waveforms, such as sawtooth or square waves. Analog oscillators are often valued for their ability to produce rich, harmonic sounds and their responsiveness to control signals from other synthesizer components.

Digital oscillators, on the other hand, are capable of generating a wide range of waveforms, including complex and evolving patterns. Digital oscillators are often more versatile than analog oscillators, and they can produce sounds that are difficult or impossible to achieve with analog circuits.

Regardless of the type of oscillator used, the output of the oscillator can be shaped and modulated in various ways to create different timbres and textures. This can include filtering, enveloping, and modulation, among other techniques. By controlling the parameters of the oscillator and other synthesizer components, it is possible to create a wide range of sounds and effects that are essential to electronic music production.

Filter

A filter is a critical component of a synthesizer that is responsible for shaping the timbre of the sound produced by the synthesizer. The filter determines the frequency content of the sound and can be used to create a wide range of timbres, from warm and mellow to bright and cutting.

There are several types of filters used in synthesizers, including low-pass, high-pass, band-pass, and notch filters. Low-pass filters allow low-frequency sounds to pass through while attenuating higher frequencies, resulting in a warm and mellow sound. High-pass filters do the opposite, allowing high-frequency sounds to pass through while attenuating lower frequencies, resulting in a bright and cutting sound. Band-pass filters allow a specific range of frequencies to pass through while attenuating frequencies outside of that range. Notch filters attenuate a specific range of frequencies while allowing all other frequencies to pass through.

Filters can be controlled using various parameters, such as cutoff frequency, resonance, and filter type. The cutoff frequency determines the frequency at which the filter starts to attenuate the sound. Resonance adds emphasis to the frequency that is closest to the cutoff frequency, resulting in a boost in volume. The filter type determines the shape of the frequency response curve, with different types providing different tonal characteristics.

Filters are a powerful tool for creating unique and interesting sounds in electronic music production. By carefully adjusting the parameters of the filter, it is possible to create a wide range of timbres and effects, from subtle enhancements to dramatic transformations. Understanding how filters work and how to use them effectively is essential for any synthesizer user looking to create their own electronic music.

Amplifier

An amplifier is a key component of a synthesizer, responsible for increasing the amplitude of the electrical signal generated by the oscillator. This signal is then sent to the filter section, where it is modified to create different sounds. The amplifier is typically composed of transistors or integrated circuits, which amplify the signal by controlling the flow of electric current. The amplifier can be adjusted to change the gain, or the amount of amplification applied to the signal. This allows the synthesizer to produce a wide range of sounds, from soft and subtle to loud and intense. The amplifier is also responsible for shaping the waveform of the signal, which can affect the overall character of the sound. In summary, the amplifier is a critical component of the synthesizer, allowing the instrument to produce a wide range of sounds and effects.

LFO (Low-Frequency Oscillator)

An LFO, or Low-Frequency Oscillator, is a crucial component of many synthesizers. It is responsible for generating a continuous waveform that oscillates at a low frequency, typically between 0.1 Hz and 10 Hz. This waveform can then be used to modulate other parameters in the synthesizer, such as the volume, filter cutoff, or envelope settings.

There are several types of LFOs, including sine, square, triangle, and sawtooth waves. Each type has its own unique sound and character, and can be used to create a wide range of electronic music styles.

One of the most common uses of an LFO is to create subtle changes in the sound over time, such as a slowly pulsating effect or a gradually changing filter cutoff. This can be used to add movement and interest to a static sound, or to create complex rhythmic patterns.

LFOs can also be used in conjunction with other synthesizer components, such as envelopes and filters, to create more complex modulation effects. For example, an LFO can be used to modulate the cutoff frequency of a filter, creating a sweeping effect that changes over time.

Overall, LFOs are a powerful tool for electronic music creators, allowing them to add depth, movement, and interest to their sounds. By understanding how LFOs work and how to use them effectively, synthesizer users can unlock a wide range of creative possibilities and produce truly unique electronic music.

ADSR (Attack, Decay, Sustain, Release) Envelope

The ADSR envelope is a fundamental component of synthesizers, responsible for shaping the volume of the sound over time. It consists of four stages: Attack, Decay, Sustain, and Release. Understanding how these stages work together is crucial to creating a wide range of electronic sounds.

Attack

The Attack stage is the initial response of the envelope when a key is pressed or a note is triggered. It determines how quickly the sound starts and how long it takes to reach its maximum volume. The attack stage is usually short, lasting only a few milliseconds, but it can have a significant impact on the overall character of the sound.

Decay

The Decay stage is the process by which the sound’s volume gradually decreases after the attack. It determines how long the sound lingers before it fades away. The decay time can be adjusted to create different timbres, from a fast decay that sounds bright and percussive to a slow decay that creates a sustained, rich sound.

Sustain

The Sustain stage is the point at which the sound reaches its maximum volume and remains constant throughout the duration of the note. This stage allows the sound to continue playing without fading away, providing a stable and consistent tone.

Release

The Release stage is the process by which the sound’s volume gradually decreases after the note is released. It determines how long it takes for the sound to fade away completely. The release stage can be adjusted to create different timbres, from a fast release that sounds abrupt to a slow release that creates a smooth decay.

In summary, the ADSR envelope is a fundamental component of synthesizers that shapes the volume of the sound over time. By understanding the attack, decay, sustain, and release stages, you can create a wide range of electronic sounds and timbres.
