Discovery Sound Technology | Nashville, TN | Full-time | Ideally Onsite, Remote Available

We predict hardware failures before they happen using ultrasound! Our main product is a handheld tool that allows technicians, primarily for HVAC, to quickly and easily detect issues, sometimes years before the issues can cause downtime. We're an eight-person company looking for our 3rd Software Developer, ideally experienced with React/React Native. Bonus points for Machine Learning, AWS, or hardware experience

Email me if you're interested: `michaelp` at company website

"Q16.16" seems to refer to fixed floating point precision (https://en.wikipedia.org/wiki/Q_(number_format)). The parent comment is unhappy that SOD doesn't support floats with 16 integer bits and 16 fractional bits. I'm unsure why lack of support for 32 bit floats is such a problem considering that SOD is suppose to run on such resource constrained devices. Is there a particular domain where this is necessary?


> "Q16.16" seems to refer to fixed floating point precision

Floating is the opposite of fixed in this context. The GP is unhappy that it doesn't support fixed point numbers of a common fixed point number format.

This is not just nitpicking, because the difference in time and implementation cost between floating and fixed point can be huge on systems where floating point operations aren't offloaded to a pipelined FPU. Fixed point arithmetic on the other hand, even if your hardware doesn't support it directly, can easily be implemented in terms of integers.


Reminds me of a Reinhold Niebuhr quote: "God, grant me the serenity to accept the things I cannot change, Courage to change the things I can, And wisdom to know the difference."

You could try adding in some simple motion, like raising your hand, before the system would start listening for hot words. Maybe connect a cheap infrared sensor to GPIO and block its view so it only detects motion at or above certain height.


Really curious on how this works, is it just bluetooth or something fancier like Google Tone[0]?

Submitted an update to the Chrome Web Store. Should appear soon. Could anyone on Ubuntu let me know if it worked please?
