Why is immersive sound the next big thing in audio?

Long gone are the days where a casual music listener or moviegoer accepted the standards of a simple stereo mix when consuming their media content. 

Audience goers and music lovers nowadays are much more knowledgeable than they used to be and their expectations have really gone through the roof as the years have gone by and new technologies have been introduced in the mainstream media - like unbelievable VR, highly immersive live shows or incredibly complex movie soundscapes. 

To adapt to this new demand is to ensure you're staying ahead in this industry. All we need to do is look at the latest announcement of the PS5, where one of their biggest selling points is 3D Audio - and how that is setting them apart from the competition.

If you've just had a casual interest in 3D Audio until now but never thought it was time to start actively using it yet - now is that time. It's time to learn all about the different aspect of 3D sound - all the ins and outs of channel-based audio, the advantages and disadvantages of object-based audio, the inner workings of ambisonics and all its variations, and everything that goes into making a binaural experience completely customized to each single listener.


What does the future hold for 3D sound?

By now I hope you realize the potential regarding 3D sound: how important it is to understand how it works and how we can use it; what the different systems are and how they're used; and a desire to  better understand this world of 3D audio that is now exploding everywhere from cinema to TV, from videogames to music, from VR to many other applications.
