3D Audio in Game Development with CRI ADX

Unlike standard game engine tools, ADX gives sound designers unprecedented control over real-time spatial audio behavior. Its combination of custom attenuation curves, dynamic filtering, and 3D soundscaping tools ensures that audio adapts naturally to gameplay scenarios.

With minimal CPU load and cross-platform compatibility, ADX provides a scalable solution for high-fidelity sound, whether you're developing for consoles, PCs, or mobile games.

So how does it work? Understanding 3D Audio in ADX

When designing sound in ADX, you can classify cues as either 2D or 3D sounds. While 2D sounds maintain a fixed position relative to the stereo field, 3D sounds adapt to the game’s environment, taking into account the player’s perspective, distance, and direction.

To achieve this, ADX uses a combination of 3D positioning and 3D panning:

> 3D Positioning: Defines the spatial placement of the sound source in the game world.

> 3D Panning: Determines how the sound is distributed across the speakers based on the listener's position.

While both techniques influence how players perceive sound, 3D positioning focuses on how the sound moves in 3D space, while panning adjusts the volume balance across different speakers.

ADX enables precise 3D audio positioning and panning, giving developers the ability to craft truly spatial sound experiences that react dynamically to the player’s actions.

ADX facilitates the set up of 3D Audio with a few features:

Directionality - or how to adjust Sound Emissions:

ADX allows you to fine-tune the way a sound is emitted by defining the inside and outside angles of the sound source. This controls how much of the sound is heard within a certain range and how it fades as it moves further from the listener.

Attenuation - or how to configure Distance:

The attenuation distance determines how the volume of a sound decreases over distance. ADX lets you define a minimum attenuation distance, within which the sound plays at full volume, and a maximum attenuation distance, beyond which it fades into silence.

Doppler effect simulation - or how to apply the Doppler Effect:

ADX enables Doppler effect simulation, meaning that if a sound source moves quickly toward or away from the player, the frequency will shift realistically—just like a passing siren in real life.

Angle Perception - or how to Fine-Tune Angle Perception effectively

Using ADX’s effective angle settings, you can define the cone within which a sound is clearly heard. The audio level gradually decreases as the listener moves from the inner to the outer range, creating a natural fade effect.

Real-Time Control - or how to leverage Adaptive Sound Attenuation Control

ADX features ASAC (Adaptive Sound Attenuation Control), which lets developers dynamically adjust audio parameters based on in-game variables. For instance, an explosion’s volume can gradually fade as a player moves away, or footsteps can be filtered differently based on distance.
