What is Granular Synthesis?
Granular synthesis is a technique of sound synthesis that involves the manipulation of small, discrete units of sound called "grains". In granular synthesis, a sound is broken down into tiny fragments or grains, each of which typically lasts only a few milliseconds. These grains are then manipulated and recombined in various ways to create new sounds.
The manipulation of grains can involve changing their duration, pitch, amplitude and other properties. Granular synthesis techniques can be used to create a wide range of sounds, from metallic and percussive sounds to complex, evolving textures.
Granular synthesis has been used in a variety of musical contexts, including experimental and electronic music. It is often used to create soundscapes and ambient textures, as well as in more rhythmic and percussive contexts. Granular synthesis can be implemented using a variety of software and hardware tools, such as granular synthesizers and digital audio workstations (DAWs).
Why using Granular Synthesis in a composition?
Granular synthesis is a versatile technique that composers may choose to use to achieve several goals. One is to create new and distinctive sounds by manipulating and combining sounds in specific ways that may not be possible with other synthesis techniques. In addition, Granular Synthesis can effectively create complex and evolving textures that can contribute to ambient soundscapes, rhythmic parts, or add depth to a composition.
Composers can also use Granular Synthesis to modify recorded sounds, such as field recordings or acoustic instruments, to produce unexpected results. In addition, Granular Synthesis is a popular choice for micro-sound composition, allowing you to work with sounds on a microscopic level to create intricate and detailed compositions. Real-time performance is another advantage of Granular Synthesis, allowing composers to manipulate sounds live and create evolving soundscapes that reflect the energy and mood of the performance. Ultimately, Granular Synthesis is a powerful and versatile tool that allows composers to experiment with new sounds and textures and to create complex and nuanced compositions.
What are the tools available for granular synthesis?
Granular synthesis can be implemented using a variety of tools, both software and hardware. Software synthesizers are a popular choice for granular synthesis and include NI Reaktor's GrainCube, Ableton Live's Granulator II, and Steinberg's Padshop. For real-time granular synthesis and live audio processing, plug-ins such as accSone's crusher-X are used. This tool is also used by sound designers to create multi-channel tracks (e.g. Atmos) or for multi-channel sound installations.
Many DAWs such as Logic Pro, Cubase, and Pro Tools include granular synthesis features and plug-ins. In terms of hardware, modular synthesizers like Mutable Instruments' Clouds and Make Noise's Morphagene are commonly used for granular synthesis. Standalone hardware synthesizers such as Bastl Instruments' MicroGranny and Qu-Bit Electronix's Nebulae are also available. In addition to these tools, sound designers and composers often develop their own scripts and software for granular synthesis workflows. In addition, Max/MSP is a visual programming language that allows the creation of custom granular synthesis patches and other sound processing tools.

How to start using Granular Synthesis
To begin using granular synthesis, you should first become familiar with the basic concepts and techniques involved. This may involve reading about granular synthesis and listening to examples of music that use the technique. You can also experiment with software or hardware granular synthesizers to get a feel for how the process works. A good starting point is the free demo of accSone's crusher-X. It comes with an in-app tutorial and runs on Windows and macOS.
Once a basic understanding of granular synthesis is established, you can begin to incorporate the technique into you compositions. This may involve using granular synthesis to create unique sounds or textures, manipulating recorded sounds, or exploring the possibilities of microsound composition.
As with any new technique, it is important for a composer to experiment and explore different approaches to granular synthesis. This may involve trying different software or hardware tools, or experimenting with different settings and parameters to create new and unique sounds. With practice and experimentation, a composer can develop a personal approach to granular synthesis and use it to create innovative and expressive music.
