> $500k Are you kidding me???! It costs so... so... so... much less. I thought automotive might be a good application, considering all the doors opened by using more DSP tricks layered in addition to source localization. (I can localize coherent sound patterns s well as coherent sound) I would love to chat with you, happy to buy a coffee or beer for your time. My email's on my profile.

  Some of these devices for automotive are large enough to surround a car on 3-4 sides, with several hundreds of microphones and the associated cables and positioning arms. Depending on where the devices he mentioned are being used, there are things like mannequins with heads and models of how humans hear for identifying sources inside a car. Here's an article about a large installation at Porsche. https://www.azom.com/article.aspx?ArticleID=18378 https://www.azom.com/article.aspx?ArticleID=18378

HRTF stuff is fun, if that's what you're referring to! :) I've worked with some of that stuff before, including the stupidly overpriced mannequin heads. > Some of these devices for automotive are large enough to surround a car on 3-4 sides, with several hundreds of microphones and the associated cables and positioning arms.

Do you work in a field that would benefit from the same results, for a fraction of the cost? Or, if not, do you have any advice on how to find and talk to these mythical industries that could pay me? It looks like Porsche wanted to build their own, in house, but I'm hoping if it costs less than a tenth as much, maybe more people would want one.

      Do you mind if I send you an email later at the address in your profile?

        Please do!!! I spent about 10 years of my life obsessed with this problem/area of research, and, when I have ability to pay rent and eat, it's the problem I'll go back to.

These are very commonly used in manufacturing plants to find leaks in compressed air lines. I had a Fluke vendor visit the ol' airplane factory to see if we could use their tools to find air leaks in low-pressure ECS system ducting. But c'mon, they are not $500k. More like $20K. https://www.fluke.com/en-us/product/industrial-imaging/sonic-industrial-imager-ii900 https://www.fluke.com/en-us/product/industrial-imaging/sonic...

  How many times cheaper would a competing product need to be for you to consider buying one? Obviously, Fluke, and the positive reputation that brand is known for, and reliable product support are worth a LOT, but I'm sure there's some $$ divisor beyond which you/someone like you would take a risk on something substantially cheaper.

    Anything in a couple hundred dollar range is an impulse buy for small independent car shops if it has potential of saving substantial time.
