[GreenKeys] Loop over IP

[Paul Heller]

“I just find it funny that you're taking a single-bit bitstream and turning into a potential 48kbps 32-bit audio stream LOL.”.   ITTY samples at 11kbps, 16bit mono to make the mp3 stream.  When I went lower on any of the settings it did not work well.

What I mean is the ability to DIRECTLY convert a current loop to something like a wifi or ethernet interface, then convert it back on the other end. Technically this would be like what iTelex does, but includes call handling/connection capability into the mix.

You can use RTTY for morse too, and out of the box the streaming software and players have buffering built in. I just find it funny that you're taking a single-bit bitstream and turning into a potential 48kbps 32-bit audio stream LOL.
