One of the most important aspects of an impactful VR experience is well-used sound. In this tutorial, we will add some office background noise as well as some localized sound to the speaker in the office.workshop
To keep all the music organized in our scenario, we are going to create and use an "Ambience Script".
Step 1: Create an "Ambience" Script (1:04 in Video)
Click on the Script icon.
Click on your script catalog.
Click on "Add New Script".
Name the script "Ambience".
Click on the checkmark to save
Collapse the script .
Close the edit section by clicking the x button.

catalog by using the > icon
Click on the Ambience script to open it on your screen.Collapse the script catalog by using the ">" icon.
Step 2: Add Scene Objects (1:59 in Video)
If your users learners will be interacting with objects in the scene, you need to add those objects to the script. In this script, we are going to be adding some music playing on a speaker, so we need to add the speaker object to the script.
As usual, we will ensure we are in the correct script by looking to see it is the active script :
...
Open the catalog drawer by clicking on the folder icon on the far right:
...
Open the "Workshop Objects" catalog.
...
(tab at top of screen).
Click the Catalog Icon
Open the Workshop Objects catalog.
Drag and Drop the Speaker into the first frame of the script:
...
Use the > icon to collapse the menu
Rename the frame "Scene Objects". Objects
Click outside of the text box to save the changes.
Save
...
Step 3: Add Background Sound (3:11 in Video)
Click the ' +' on the main frame to create a new frame at the top level:
...
Open the Media Catalog by clicking on the media icon on the far right:
...
Click on "Workshop Music". In this area, (you can preview the audio files by clicking on the play button. Select )
Drag and Drop one of the music types and drag it songs into the new frame.
Video
Click on the ">" icon Resource area
Click > to collapse the music catalog.We want this background noise :
Select Loop to continue music throughout the scenario, so check the "loop" option.
Select the "Ambient" track. This means that this sound is the lowest priority if there are several sounds playing at once.
...
Save the Script.
Re-name the frame with the music Background Sound
Before you test you need to launch this "Ambience" script from the Director Script:
Open the Director Script.
Create a new top-level frame and name it "Ambience".
Drag and drop the Ambience script from the script catalog into the frame.
Save
Note that the welcome message and the ambient music will start at the same time - when you launch the experience. Here is what it would look like:

STOP: Save and Test. Play the scenario now. You will notice that the background sound is playing. It is too loud. We will adjust this in the next step.
Step 4: Adjust Volume of Background Sound (5:26 in Video)
In order to make the background sound quieter, use the "Volume" field on the audio resource in the frame. Volume is set from 0 to 1 with 0 being silent and 1 being maximum volume.
Open your the Ambience script.
Open the "Background " Sound frame.
Adjust the volume until it seems right to you. In this tutorial we have set it to 0.1:
...
Save
STOP: Save and Test. The sound should now be quieter now.
Step 5: Add Music Coming from the Speaker (6:10 in Video)
We want the learner to hear the music coming directly from the speaker in the scene.
Create another new frame in the "Ambience" script and call it "Speaker Music":
...
Navigate back to the "Workplace Music" media catalog (click on the Media Items icon>click on "Workshop Music") and choose a song that you would like to be playing on the speaker on the floor.
Drag and drop the music into the center of your screen.
Collapse the Media catalog by using the ">" icon.
In order to make it sound like the music is coming from the speaker, we give the sound an anchor.
Chose "Speaker" from the anchor dropdown on the resource.
Loop the track so that it plays continuously.
Choose the "Ambient" track so that it has the lowest priority of sounds.
...
Open Ambience script
Go to the Background Sound frame
Under Anchor choose the Speaker object
Save
STOP: Save and Test. You should now hear the ambient background noise and the sound coming from the speaker on the workshop floor. You might also want to adjust the volume once you've tested it.
You will notice that you are now hearing two types of music. Let's fix this.
In the Ambience script, click on the "Background Sound" frame.
Change the Volume to 0.
Save the script.
GIF
STOP: Save and Test. You should now hear only the sound coming from the speaker on the workshop floor.
While you are in the workshop you can move around the scene by clicking on the green arrows using the laser pointer. As you move around the workshop, notice that the volume changes based on your distance from the speaker.

Challenge: instead of looping the speaker music, you could create a playlist that starts the next song when the previous one has finished playing. You could use subframes and object event conditions to play a new song when the last one finishes or "closes". Try to cue up a few songs using this pattern. |

Training Notes
Key Takeaways from Tutorial 2
If users learners will be interacting with objects in the scene, you need to add those objects to a script via the Catalog.
Always test audio files to ensure optimal sound levels.
Any audio on Ambient Track will have the lowest priority if there are several sounds playing at once.
When you anchor sounds to an object the sound will change based on your location in the scene.
Within the VR scene, use the green arrows to move around.
