Soundcamera - visualizes sound - useful for our hobby?


I saw a kickstarter for a audio visualization device and wondered if it had application for audio designers or end users?  There's a video that explains it all.

Aparrently devices like this exist but are 100,000 or more and require complex set up. This device is about 5000 euro.

@emailists. Fascinating article. Thanks for idea generating post. Very appreciated. One of our hobbies biggest uses will, I think, be noise / vibration analyses. Incredibly worthwhile, as all those who use extremely effective equipment stands and isolation platforms, with highly resolving gear—incuding even CD and DVD players—, can attest. An economical,highly refined, easy to use sound analysis device will be a game changer.
Thank goodness for all digital refinements. One day their mathematical and processing speed will be able to truly reproduce high quality analog as we hear it though our existing equipment. Digital’s ability to work effectively from 1 hz to 100,000+ hertz, will soon mean superior sound for us music lovers. 
emailists: I saw your post on having PS BHK 300s with your TAD CR-1s.  I just got a pair of used CR-1s (MK I) and have a BHK 250 have a question on what your using for the BHK tubes.  I'd like to touch based with you....

Thanks
Mike
