How spatial audio works for websites?

Spatial audio, also known as 3D audio, mimics the natural way humans perceive sound in a three-dimensional space.

It creates the illusion of sounds coming from different directions and distances, providing a more immersive and realistic auditory experience.

Here’s how it works for websites💡

✅ 3D Sound Simulation

Spatial audio replicates how sound behaves in a three-dimensional space.

This means sounds can seem to come from above, below, behind, in front of, or beside the listener.

✅ Head-Related Transfer Function (HRTF)

HRTF is a set of algorithms that mimic how our ears receive sounds from different directions and distances.

It accounts for the fact that sounds are altered by the shape of our ears, head, and torso before reaching our eardrums.

This alteration helps our brain understand the sound’s location.

✅ Binaural Recording Techniques

To create spatial audio content, binaural recording is often used.

This involves placing two microphones in the ears of a dummy head or a human to record sound exactly as it would be heard by a person.

When played back through headphones, this creates a highly realistic and spatially accurate sound experience.

✅ Directional Audio Cues

As users navigate through a website, spatial audio can adjust in real-time.

For example, if a sound source is to the right of the user and they turn their head towards it, the sound will naturally seem to come from straight ahead, just as it would in real life.

✅ Distance and Environment Effects

Spatial audio also simulates how sound changes with distance and in different environments.

Sounds can become softer, more muffled, or change in quality as they get further away or as the environment changes (like echoing in a large hall or being absorbed in a densely furnished room).

TL ; DR

By implementing spatial audio on your website, you can create a more immersive and engaging experience for your users.
