What is 3D audio?

3D audio is just one element in creating a truly immersive experience. We are all familiar with stereo audio, where sounds can be delivered through a left or right speaker or headphones, and most of us will have experienced surround sound at some point. Be it at the cinema or at home where speakers are strategically placed to simulate sounds coming from above or behind you.

Well, 3D audio works in a similar way, only through headphones as the delivery format.

3D audio, also known as binaural sound, places you the listener in the middle of the action giving you a truly 360 degree audio experience.

Pop your headphones on and let’s have a listen to a sample here:

 

 

How does it work?

The concept is simple. Two directional microphones placed approximately the same distance apart as your ears, pick up the sounds around you. If there is sound happening on your left, the left microphone will record that sound louder than the right. As the sound gets closer it will get louder and as the sound passes to the right ear it will be recorded louder through the right hand microphone. Simple.

When this audio is played back through headphones, the original positioning, depth and volume of the recorded sound is simulated back to the listener as if the sound is happening around them!

Why use 3D audio?

3D audio can be paired with any of our motion based visual services including virtual reality, 360 videos, augmented reality or mixed reality. 3D audio really is the icing on the cake for simulating any virtual environment for a unique and immersive experience.

Can I use 3D audio today?

All of the most current virtual reality headsets support 3D audio including Playstation VR, Oculus Rift and Samsung Gear VR, so if you have a game or movie that uses 3D audio you can experience the power of 3D audio today in the comfort of your own home!

3D audio isn’t limited to the expensive VR hardware though, as you heard earlier in the sample above, an online video and some headphones could wow your audience just as well.

What could it be used for?

3D audio can be used everywhere. Product launches, corporate videos, elevated pitches, games or virtual tours. The possibilities are truly endless!

So why not add the wow factor to your next video or VR project and let us produce your companies first immersive experience to your customers.
