[TowerTalk] Arrival Angle Application

[David Gilbert]

Not too long ago I mentioned that I was working on a application that 
would hopefully measure and display the arrival angle of an RF signal by 
feeding the audio from two phase locked receivers into the sound card of 
a computer and doing the processing on a browser web page.  The 
application is now functional and I have created a YouTube video 
describing what I tried to do, how the application works, and to what 
degree I was successful.  At 50 minutes it's pretty long so if you 
decide to watch it you might want to click on the YouTube settings icon 
at the lower right to speed it up.  My production skills are limited so 
please take that into account.

The YouTube video is here:

The actual application is here:

You can run the app directly from my web page but you can also just 
download it (right-click, save page as .html) and run it locally on your 
own computer.  It's totally free and comes with no guarantees of 
literally anything.

I'd appreciate any comments or suggestions, and I'll try to answer 
questions.

p.s.  The application was written by OpenAI's Codex coding agent.  I 
created the layout and the prompts that specified how it should work, 
and I did a lot of refining, but I didn't write a single byte of the 
actual code.  We're in a new era of custom software for almost any use 
no matter how limited the audience may be for it.
