Add Your Audio

Once you’ve created music or ambient sounds for your domain, you need to add the sound and its assets to the Marketplace. To sell audio on the marketplace, you will need the following assets:

  • WAV or MP3 file
  • Script file (sound emitter script)
  • FBX file (for the entity to which you will attach the sound emitter script)
  • JSON file

Prepare Your Script File

  1. In Interface, pull up your HUD or Tablet and go to Create.
  2. Click on the entity you previously created to edit its properties.
  3. In the ‘Properties’ tab, scroll down to ‘Script’ and your script’s path or URL.
  4. Test your script file to see if your audio plays in High Fidelity.

If you don’t have a sound emitter script, you can create one by modifying this sample: soundLoopEmitter.js.
