I started in 2010 with acoustic measurments. In 2012 I started with S.A.P.-measurment. We improved it during time. Even in 2016 I was able to bring to an even higher level.
Beside this I have done a lot of reseach in electricity, smog, magnetism and other things what influences audio. I communicate a lot with specialists in different parts. I use their technical support to create things I have in my head.
At this moment there are different products I have in my head what will bring audio to a much higher level than the poor level what we hear now. The things I created are so much more effective than other stuff in audio.
The problem in audio is that people almost don't test and communicate with other people. It looks like audio is freezed. When you do research you will see how much there is to improve.
In vision we do the same. We just bought the best Calman (Studio) system to calibrate screens and projectors. In my world to need to push the limits tot the max. Only the best is what matters, everything below it is for losers.
