Not working on Macbook or android (Chrome)

[vfalanis]

I've tried to test the provided example, however I can't get it to work. I've tested it on two Macbooks (with chrome) and two android phones with no luck. On chrome, I can see the audio icon meaning it is transmitting audio but I can't receive it on the other device.
Are there any prerequisites or specs for getting this to work?

This is very much an idea more than a proper implementation. I've only spent a little bit of time looking at how best to send data, what frequencies work best, etc, etc. Even if you are in a quiet room with two computers that are about 5m away from each-other, the transmission will be spotty.

That said, a few things to check:

• When viewing https://korynunn.github.io/uscp/example/ make sure that the browser can both transmit audio AND access your microphone.
• use this page: https://rawgit.com/borismus/spectrogram/master/index.html to watch the signal being heard by sending a message. It will appear as tiny lines right at the very top of the spectrum. uscp transmits between 17914 and 20671 hz, so that page can plot at least some of the sound.
• Use Audacity to record sounds as they are sent, and use the spectrogram view to check that they are being heard by the mic correctly.
