3D Spatial Audio

3D Spatial Audio brings the real-world sound experience to the virtual world, providing an immersive audio experience for users. Agora's spatial audio technology enables you to simulate the propagation characteristics of sound in a physical environment within a virtual interactive scene.

Spatial audio comparison

  • Ultra-realistic space shaping effect

    Utilize technologies such as range audio, sound blur, and air attenuation simulation to perfectly simulate the real auditory experience.

    • Set the spatial positions of users in real time to give a sense of change in the distance, direction, and orientation of other users.
    • Update the spatial position of the media player, to add a sense of space to background sounds, accompaniments, and other media resources.
    • Add 3D Spatial Audio effects such as sound blurring and air attenuation by adjusting audio settings to perfectly simulate the real audio experience.
  • 3D High Fidelity

    • Sound effects are processed and rendered based on the facial orientation, sound source orientation, and relative position of the sound source in 3D space.
    • Supports 48 kHz full-band sampling and 3D high-fidelity audio processing and rendering.
  • Multi-platform support

    Supports iOS, Android, macOS, Windows, Web, Unity, Flutter, React Native, Electron, Unreal and other platforms.

  • Ultra-low latency, low power consumption, and low cost

    The spatial audio algorithm adopts an advanced front-end processing mode and synchronizes spatial coordinates through cloud services. The end-cloud collaborative processing mode effectively reduces overall latency and power consumption.

Compared to traditional stereo, which relies on left and right channels, spatial audio technology greatly enhances the depth and realism of sound. The following table highlights these enhancements:

FeatureTraditional StereoAgora Spatial Audio
DimensionalityLeft and right dimensionsRepresents sound in a full 3D space using the x, y, and z axes of the world coordinate system, corresponding to right, top, and front dimensions
Spatial PerceptionAdjust the volume of the left and right channels to create a spatial soundUtilizes advanced spatial audio algorithms to create a realistic soundscape by manipulating parameters like distance, direction, and orientation
User ExperienceFlatImmersive, three-dimensional, and natural, delivering a realistic auditory experience
