Here you can fond some picture about my studio in the past. Yep. An event happened in march... In that month Markus Guglielmi and me take some acoustical measures in order to discover WHY my mixes were always too much "high sparkle" biased. So we discovered such a very bad thing: the acoustical preparation of the Studio were not sufficient to cope with the energy projected by the speakers under 1000 Hz... And this was not someone promise me when I bougth absorbers, bass traps and so on!
Absorbers
Corner Bass Traps
I had some cornertraps and basstraps in the rear part of the studio indeed.
Measures were absolutely clear I had some hill and dip in the signal response.
