Hi,
I would like to share some of my experience as well as my research about Immersive audio.
All started from a business trip to Switzerland, after that, I spend 2 days visiting Illusonic, Weiss Engineering (I own Weiss DAC202, a very good DAC, I paid $3000 and used for more than 5 years without any issues) and PSI (Speaker manufacture). And I start to read about Immersive audio.
So, let's start with a very basic and simple question: what exactly we want to hear from speakers? I assume that all the components are fully transparent. I think, most of us will prefer that what we hear when we sit in front of, for example, a piano - 1 sound source, will be the same as what we hear from 2 speakers - 2 sound sources. That is where the problem begins - Crosstalk
When you hear from a piano, both of your ears will hear the sound from the piano. However, when you reproduce the sound via 2 speakers, you left ear will hear the sound from the left speaker and also the right speaker; your right ear will hear the sound from the right speaker and also from the left speaker. Hence, from the beginning, what you hear is already very different.
Weiss Engineering and Illusonic have 2 different ways to solve this problem, the method is different, but the purpose is the same, they try to cancel the audio signal from left speaker comes to the right ear and vice versa - Crosstalk Cancelation (or XTC)
Weiss Engineering approaches by using the ideal of Binaural Audio, which is not new: create the filter to stop the crosstalk. Ambiosonics and Princeton 3D3A (can also call BACCH) share the same idea but different in the way they handle the filters. All of them will not change or modify the signal
Illusonic approaches by heavily modifying the signal and send to a system of speakers around you. It will be the same approach to Auro3D but the way he modified the sound is unique.
Please note that all of them use the stereo records.
Another "physic" method that you can try, is using a very efficient absorber for mid, high, very high frequency and put it between 2 speakers. So crosstalk signal will be absorbed.
I have tried for 2 days, and to be honest, the sound is really really good, the soundstage is very very big, deep. It is like you are using a magnifying glass.
So, what do you think about that?
Have a nice day.
