Sound is integral to whatever media we watch, whether silent or loud. There are two kinds of sound in the film world: diegetic and non-diegetic.

Read on to learn more about diegetic sound and how it’s created.

What is diegetic sound?

Diegetic sound (or actual sound) is any sound whose source is directly visible or (implied to be present) on the screen.

The sound source doesn’t necessarily need to be seen on screen, as long as your audience understands that it is coming from that scene. Think of them as natural in that story world: If the characters can hear them, then it’s diegetic.

It has evolved from the Greek word diegesis, meaning narrative or narration.

How is diegetic sound created?

Just because the diegetic sound comes from the world within the film or TV show doesn’t mean that sound occurred live or onset.

Many of these diegetic sounds are recorded in studios by sound engineers, making them clearer and more realistic.

3 Examples of diegetic sound

1. Character dialogue

This is the most obvious example of diegetic sound.

Dialogue most often occurs live on set, but sometimes it needs to be recorded in a studio due to technical difficulties or because a line of dialogue wasn’t recorded live.

2. Sound effects

These are added for a dramatic or realistic effect and are usually added post-production by a sound engineer. Some examples are raindrops, ambulance sirens, etc.

3. Music coming from within the film

This is a fantastic way to immerse your audience in your media. The booming music from someone’s headphones or songs blasting at a nightclub is all diegetic sound.
