As you may recall, NFS Audio had created a room tweak wherein laser light of a certain frequency was used to make the air in the listening room more 'coherent' and thereby more effectively couple the speaker/air interface and improve sound quality.
Also, the more 'coherent air' in the room iteself becomes a better conductor of sound, with less 'air induced' distortion products added to the music signal once it leaves the speaker.
If you look closely, you'll see how well it makes the speakers 'vanish!'
Now, the new part:
Any room tweak worth its salt should be able to improve the sound of live music as well as recorded music, so the 'coherent air' tweak has now been used in a live venue...
Without being too visually obtrusive, this tweak was demo'd for an audience at a live show. The artist is John Batdorf (of Batdorf and Rodney) playing a solo show in a room measuring about 30 feet by 65 feet...
The pics are from my iPhone, apologies for the low rez. However, even with a low rez picture you can plainly see how the sound was improved using the 'coherent air' tweak to tune the room.
All in attendance were well pleased.
Further testing data will be forthcoming in January 2011.
