Interactive audio demonstration

Hear how language streams separate in space.

Use the demo to play multiple announcements at once, then move languages left, center, or right to hear the spatial effect. For this demo, a maximum of 3 languages is recommended using the following example: slide one language to the left, another to the right, and keep one in the center.

1

Click a language box to start that announcement. Active boxes turn green.

2

Drag the box left, right, or back to center to change where the voice appears to come from.

3

Click the box again to stop that language.

For the clearest left/right effect, use headphones or separated speakers. Your browser may wait until the first click before allowing audio playback.
