Quietnet: Chat client that works over near-ultrasonic sound

Re: Quietnet: Chat client that works over near-ultrasonic sound
#62It looks like it would interoperate with standard amateur radio PSK-31 software if you set the ham radio software to 19043 Hz (instead of more typical 500-2000 or so Hz) Over the last 15 years or so there have been a lot of PSK-31 software interfaces, so there's probably one that appeals to everyone. I would imagine other modulation schemes would work in the ultrasound range, if you wanted to try SSTV or RTTY or perh…
Do you mean the sound waves would generate radio waves somehow, or are you thinking of the speaker generating EM interference as well? How strong would you expect that to be?

Heh, I just visualized my laptop keyboard transposed onto an 88 key piano, and then tried to imagine what a typical vim session would sound like on it...
Obviously Emacs sessions would sound better, as Emacs already is set up to use chords...
Funny :)
As long as you hit middle C1 on every chord regardless of whether or not it's a duff chord or not...
At least with vi, you can play one fingered and make an acceptable tune ;)
Sure Douglas Hofstadter could write a book about that...

You are using Python 3.3, but the script is for Python 2.x where print is a built-in rather than a function. Welcome to the fragmented world of Python.

I think tones in our hearing range would be a bad idea. From what I remember of my music theory class, our brains (through either nature or nurture) don't like discordant sounds like that for a long time. In fact, I believe it's been used as a torture device in the past, although I'm guessing it wasn't just a weird jumble of notes in that case. I don't think I'd be very good at programming in any case.
Click noises have no real tone character so could probably work. My keyboard already makes those anyway.
True, but as you alluded to yourself, those aren't really 'tones'. The parent was talking about a keyboard that sounded like a piano.

No, just audio. If PSK-31 modulation works, Olivia will work better.
