How does BACCH Filter work? Optimized Crosstalk Cancellation for 3D Audio over two loudspeakers

CKKeung

W.S. has turned from a customer to the HK dealer of BACCH.

Avantgarde HK is collaborating with W.S./BACCH ?

聽講呢個filter好勁，可以將兩聲道變成聽headphone咁，左聲道入左邊耳，右聲道入右邊耳，但相信要用人頭咪之類的錄音，先至可以做到好嘅3D效果。

Very interesting gear !
Does this BACCH filter act like a preamp ?
Can it cope with the existing hifi system ?
I do a few researches but cannot find out how it will cope with the existing music system.

I downloaded some sample files it processed.  Pretty good 3D effect.   If they sell the software, you can pre-process it and save it for your CAS (of course, they are not selling it).  There is no choice and you need to pay for the hardware processing unit.

Best outcome if you let them calibrate your listening position and your in-ear sound reception.

There are some low end product already embedded it.

I have seen news that some Korean TV manufacture is licensing this technology to built-in to the TV speaker system.  

A very important audio technology to watch.

There is a competing technology called R.A.C.E.   It is not as good as the BACCH.  

If you are using iPhone, there is an app "Ambiophonic AP" free to download.

Ambiophonics is totally different from BACCH. Ambiophonics it's very unnatural, not listernable at all.
