Spatial audio is a critical component of an immersive VR experience and can be added to content in several ways with the Composer. If you haven't learned the basics of the Composer, make sure to read our "Getting Started with the Composer" article first.
Adding audio is easy. Just right-click on the bottom of a node. Select the Audio Tag and then click on "Select Asset" to add your audio file.
Types of Audio Supported
Standard: results in 2D audio with no positional effects.
Point: creates positional audio that is played at a point in 3D space (values are in meters, 1 = 1 meter). Coordinate system conforms to the following diagram:
You can use the point audio option to easily add spatial audio to your content even if you only have mono and stereo audio tracks.
EPP (Equal Power Panning): places audio within a 360° of the user. The rotation is in counterclockwise position. i.e. 90° = to the left.
Ambisonics B-Format: this option allows you to add any audio recorded using the Ambisonics B-Format, which is a full sphere surround sound technique.
Start Time: is the time into the node at which the audio clip becomes active and plays.
Duration: the length of the audio asset as it plays, setting a shorter duration will cut the audio off early. A 0 duration implies the length of the asset.
Audio Transition: determines whether or not the audio fades in / fades out in seconds. (i.e. .5 = over half a second).
Volume: a percent of how loud the audio will be based on it's original dB levels.
