Introduction


If you have never heard about / in 3D-Audio and if terms such as Auralization, Binaural, Transaural, HRTF and so on, sound Greek to you, then you’re in the right place!

Well, you don’t have to learn Greek, in order to enjoy 3D-Audio. The impatient listener can jump directly to the ARIA-3D Media player, for an immediate 3D-Audio experience. Yet, it is strongly suggested to keep up reading.

If you are interested in learning more about the underlying principles of the technology behind the scenes, then we have a guide for you here: Introduction to Binaural Technonoly.

Defining 3D-Sound & 3D-Audio


In this section, we’ll give some simple and clear explanations about 3D-Audio, through a series of questions & answers.

It should be noted, that although the terms 3D-Sound and 3D-Audio are frequently used interchangeably, in the context of the current primer, it would be wise to differentiate them.

What is 3D-Sound?

3D-Sound refers to the positional sounds we perceive in the 3D-Space surrounding us.
To put it simply: 3D-Sound refers to the way we hear.

What is 3D-Audio?

3D-Audio is the reproduction of 3D-Sound in our ears, via a chain of electronic devices.
To put it simply: 3D-Audio is simulation of 3D-Sound.

How can one listen in 3D?

A 3D-Audio engine is a must (software or hardware), plus a set of sound producing devices.
To put it simply: With a 3D-Audio Engine and via Headphones or over Speakers.

Should the Headphones be Special?

As always, the quality of the perception depends on the quality of the device. The better the headphones, the better the experience.
To put it simply: No, they should not, but you’d better use some decent ones.

How many speakers?

Depending of the technology employed, one could use from two speakers to countless.
To put it simply: A pair of speakers is enough.

Should the Speakers be Special?

Again, as always, the quality of the perception depends on the quality of the device. The better the speakers, the better the experience.
To put it simply: No, they should not. Even laptop speakers would do, but you’d better use some decent ones.
