Sounds

You can add sound to your 3D scenes on Sketchfab. Sound / audio is great to make your scene more immersive, especially in VR. You can adjust the volume, position sounds in space, and synchronize them with an animation.

Sound on Sketchfab is a Work in Progress and it's not yet available on every platform. See Compatibility.

The sound tools are available in 3D Settings.

  • From your model, go to Settings → 3D Settings or add "/edit" to the end of any model URL.
  • Select the Sound panel in the top left.

Managing sound tracks

Sound tracks have the following options:

  • Loop: Enable this option to make the sound repeat over and over.
  • 3D: Enable this options to make the sound positioned in space. When enabled, you can move the sound in the 3D viewport. You can also adjust the radius of the sound by making the sphere smaller or larger. Inside the sphere the volume is constant. Outside the sphere, the volume falls off. You can change the attenuation between Exponential and Linear. For reference, sound is spatialized with the HTML5 Web Audio API.
  • Volume: Adjust the default volume of the sound.
  • Sync animation: When the model is animated, this will make the sound to start/restart playing when the animation reaches the given time. If the model has multiple animations, synchronization is only supported on the first animation.
  • Stick to closest geometry: When a model is animated and your sound is set to 3D, you can choose to make it stick to and follow the nearest object around the scene.

Sound synchronization only works for animation playing at x1.0 speed.
Click the clock icon to fill the time with the current time of the animation.
