Understanding Noise in the Context of Synthesis

Before diving into the how-tos, it's important to understand what noise actually is in electronic music and synthesis. Noise refers to a sound signal that contains a broad spectrum of frequencies, often with no discernible pitch or tonal center. Instead of a clear note or melody, noise provides a textured, chaotic, or atmospheric element that can add richness and depth to your sound palette.

Types of Noise

Noise can be categorized based on its spectral content and statistical properties:

• White Noise: Contains all frequencies at equal intensity. It sounds like static and is often used for percussion, effects, or as a basis for filtering.
• Pink Noise: Has equal energy per octave, resulting in a warmer, more balanced sound compared to white noise. It’s useful for sound masking and mastering.
• Brownian (Red) Noise: Emphasizes lower frequencies with a deeper, rumbling quality. Often used for relaxation sounds or bass textures.
• Blue and Violet Noise: Emphasize higher frequencies, creating a bright, hissing sound, useful for special effects.

Tools for Creating Noise in Synthesis

Synthesizers and audio processing tools offer various methods to generate and shape noise. The choice depends on your workflow, desired sound, and available hardware or software.

Hardware Synthesizers and Noise Generators

• Many analog synthesizers include dedicated noise generators. For example, classic synths like the Roland SH-101 or Korg MS-20 have built-in noise sources.

In the vast universe of sound creation, few tools are as versatile and fascinating as the synthesizer. Whether you're an aspiring musician, a sound designer, or simply a curious audiophile, understanding how to make noise with a synthesizer opens up a world of limitless sonic possibilities. This guide aims to demystify the process of crafting noise and shaping sounds using synthesizers, providing both technical insights and practical tips for enthusiasts at all levels.

What Is Sound Synthesis?

Before diving into how to make noise, it’s essential to understand what sound synthesis is. At its core, synthesis involves generating audio signals via electronic devices or software to create sounds. Unlike recording traditional instruments, synthesis allows for the creation of entirely new sounds or the modification of existing ones, offering a playground for creativity.

Types of Synthesis

There are several methods of synthesis, each with unique characteristics:

• Subtractive Synthesis: Starts with rich, harmonically complex waveforms and filters out parts of the sound to shape the final tone.
• Additive Synthesis: Builds sounds by adding together many simple sine waves at different frequencies and amplitudes.
• FM (Frequency Modulation) Synthesis: Uses one waveform (carrier) modulated by another (modulator) to produce complex, often metallic or bell-like sounds.
• Wavetable Synthesis: Plays back a series of pre-recorded waveforms, allowing for dynamic timbral changes.
• Granular Synthesis: Breaks sound into tiny grains and manipulates them to produce textures and noise.

While each method has its unique approach, this guide primarily focuses on how to generate noise—an essential element across many synthesis techniques.

Understanding Noise in Synthesis

In audio, noise refers to a sound that contains a broad spectrum of frequencies, with no distinct pitch or harmonic structure. It’s used in various contexts, from creating atmospheric textures and percussion sounds to adding realism in sound effects.

Types of Noise

• White Noise: Contains equal energy across all frequencies, resulting in a bright, hissing sound.
• Pink Noise: Power decreases with increasing frequency, giving a warmer, more natural sound.
• Brownian (Red) Noise: Power decreases more steeply with frequency, producing a deep, rumbling noise.

These different noise types are essential tools for sound designers, each suited to specific applications.

How to Generate Noise Using Synthesizers

Generating noise is a fundamental feature of most synthesizers, whether hardware or software. Here’s a detailed look at how to do it.

Using Hardware Synthesizers

Most hardware synthesizers include a dedicated noise generator or a noise oscillator.

Steps:

1. Select the Noise Oscillator: Many synthesizers label this as “Noise” or “OSC Noise.” Turn to this setting.
2. Choose Noise Type: Some synths allow selection between white, pink, or other noise types.
3. Adjust Level/Amplitude: Set the volume or amplitude of the noise to fit your patch.
4. Shape the Noise: Use filters, envelopes, and modulation to sculpt the noise further.

Example: On a classic Roland SH-101, switching to the noise source provides a static-like sound that you can filter and modulate.

Using Software Synthesizers

Most DAWs (Digital Audio Workstations) and software synths provide a noise generator.

Steps:

1. Insert a Noise Generator Module: Many synth plugins include “Noise” as an oscillator choice.
2. Select Noise Type: Choose between white, pink, or other noise options if available.
3. Configure Parameters: Adjust amplitude, panning, and filters.
4. Layer or Modulate: Combine with other oscillators or modulate parameters for complex textures.

Popular Plugins with Noise Generators:

• Serum by Xfer Records

Shaping Noise: Filters, Envelopes, and Modulation

Generating noise alone is just the start. The real artistry lies in shaping that raw sound into something musically and creatively useful.

Filtering Noise

Filters are the primary tools for sculpting noise.

• High-pass filter (HPF): Removes low frequencies, emphasizing the higher spectrum.
• Low-pass filter (LPF): Attenuates high frequencies, resulting in a warmer, duller noise.
• Band-pass filter (BPF): Isolates a specific frequency band.
• Notch filter: Removes a narrow band, creating a hollow or comb-filtered effect.

Practical tip: Using a band-pass filter on noise can produce a “whooshing” or “wind” sound, often used in effects.

Envelopes

An envelope defines how a sound evolves over time—attack, decay, sustain, and release (ADSR).

• Applying an envelope to noise: Creates dynamic textures, such as a sudden burst or a gradual fade.
• Example: Short attack and decay with no sustain produce a quick “snap,” useful for percussion or sound effects.

Modulation

Modulation involves changing parameters over time, adding movement and complexity.

• LFO (Low-Frequency Oscillator): Can modulate filter cutoff, amplitude, or pitch of noise for vibrato, tremolo, or rhythmic effects.
• FM or Ring Modulation: Combine noise with other oscillators to produce metallic or gritty textures.

Creating Different Noise Textures

Beyond generating raw noise, sound designers often aim to craft specific textures for various applications. Here are some techniques:

Wind and Atmospheric Sounds

• Start with white noise.
• Apply a band-pass filter to focus on certain frequency ranges.
• Use a slow, random LFO to modulate filter cutoff for a swirling effect.
• Apply reverb and delay for space and depth.

Percussive Noises

• Use noise with a quick attack envelope.
• Filter out unnecessary frequencies with a high-pass filter.
• Modulate amplitude with an envelope to create a “hit” sound.
• Layer with pitch modulation for added realism.

Mechanical and Gritty Textures

• Combine pink or brown noise for warmth.
• Use distortion or saturation effects to add grit.
• Modulate parameters to simulate movement or machinery.

Advanced Techniques for Making Noise

Breaks noise into tiny grains and reassembles or manipulates them. This technique produces complex textures, evolving soundscapes, and surreal effects.

• Use granular modules or software.
• Control grain size, density, and playback rate.
• Modulate these parameters for animated textures.

Spectral Processing

Use spectral effects to analyze and reshape the frequency content of noise.

• Apply spectral filtering or EQ.
• Use spectral delay or granular effects for shimmering textures.
• Combine with visual feedback for experimental sound design.

Layering and Combining Noise Sources

Blending different noise types and adding layered effects can create rich, immersive sounds:

• Layer white, pink, and brown noise.
• Apply different filters and modulations to each layer.
• Use panning and spatial effects for stereo width.

Practical Tips for Using Noise Creatively

• Start simple: Experiment with basic noise and filters before diving into complex modulations.
• Use automation: Automate filter cutoff, amplitude, or other parameters to add movement.
• Experiment with effects: Reverb, delay, distortion, and modulation effects can radically transform noise textures.
• Layer carefully: Combine multiple noise sources for richer sounds but avoid clutter.
