Smyth Realiser is a product that we know and it's a pretty cool product.
It performs a measurement in a particular room and for a particular person so that you get a virtual experience of that particular hifi room.
One of the reasons why we ventured into this is that we have found that the need for individualization is less important than generally thought, provided that the HRTFs are modelled correctly... just as in room correction, trying to model every tiny detail of a head-related transfer function can lead to errors.
The solution needs to be robust to work for everyone.
Also we have not tried to make a system that takes a given HiFi room and transforms that into headphones.
We rather wanted to create an ideal listening space... real rooms and hifi systems have lots of problems that color the sound, which is exactly what we wanted to avoid.
In a sense the virtual HiFi room could be the ultimate room correction solution!
