Sound Design

Sound design is making a sound that doesn't exist yet. A laser blast for a film, a synth lead for a chorus, a UI ping for a phone — all of these start with someone asking "what should this sound like?" and then answering through a combination of synthesis, recording, and processing.

It's a skill, not a profession. A film sound designer, a game audio designer, a synth-patch sound designer, and a record producer are all doing related work with different deliverables.

The Toolset

Sound design happens at the intersection of several disciplines:

• Synthesis — generating raw material from oscillators, filters, and modulation.
• Field recording — capturing real-world sounds (often the building blocks).
• Sample manipulation — pitch-shifting, time-stretching, reversing, granulating.
• Processing — EQ, compression, distortion, reverb, modulation effects.
• Layering — combining multiple sounds into one perceived object.

Most great sound design uses several of these in combination.

Layering: The Universal Technique

A film sword being drawn might be:

• A real sword unsheath, recorded in a quiet room.
• A metallic ring (a wine glass struck, recorded close).
• A whoosh (a tonal whoosh from synthesised noise, EQ'd and sweep-filtered).
• A sub-bass thump (a sine wave at 60 Hz, gated by the transient).

The four layers, balanced and aligned, become "a sword being drawn" in the listener's mind.

This same layering principle scales:

• Drums. Kick = real kick + sub-bass synth + transient sample.
• Synth leads. Saw oscillator + sub oscillator + noise transient.
• Risers. White noise + filter sweep + pitched element.

Recontextualising Source Material

Some of the best sound design is real-world audio recorded for one purpose and used for another:

• The original Wilhelm Scream is a 1951 voice recording.
• The TIE Fighter sound in Star Wars is an elephant call layered with a car driving on wet pavement.
• A signature snare from a 1971 Stax record powers a 2024 hip-hop track.

The technique is: listen widely, record everything, sort obsessively, and have a search-able library you can pull from when an idea hits.

Synthesised Sound Design

For sounds that don't exist in nature — sci-fi weapons, alien creatures, futuristic UI elements — synthesis is the source. Subtractive synths give you raw material; FM and wavetable synths give you complex, evolving textures; granular synths give you abstract clouds.

Sound designers who work primarily in the box typically have a small handful of synths they know intimately rather than a large collection they barely understand.

Common Mistakes

Reaching for presets. Presets are useful starting points but a sound made entirely from "Default Lead 12" doesn't feel personal. Modify aggressively.

Forgetting silence. A great sound effect is often defined by what surrounds it. A laser blast over silence reads better than the same laser blast over background noise.

Over-layering. Four well-chosen layers usually beat ten sloppy ones. Each layer should have a clear job.

Mixing as you design. Get the design right at unity gain, then mix. Designing-while-mixing leads to sounds that fall apart when their context changes.
