Audio Network - send data over sound in JavaScript

THIS PROJECT IS STILL UNDER DEVELOPMENT

Old PSK approach. It will be deprecated soon!

If you don't want to dig into Audio Network internals you can use following 'Quick Config' buttons to setup some common configurations:

Default settings used when this page loads. The most reliable PSK transmission scheme - Binary Phase Shift Keying:
PSK-2 (BPSK), Baud-4 - 4 bits/s
Two times faster baud rate (8) and two times more PSK symbols (PSK-4, Quadrature Phase Shift Keying):
PSK-4 (QPSK), Baud-8 - 16 bits/s
10 symbols PSK scheme and baud 4 - you can send for example phone numbers by directly using PSK symbols:
PSK-10, Baud-4 - 4 decimalDigits/s

Experiments with higher speeds (under testing - it may blow the app):
PSK-8, Baud-16 - 48 bits/s PSK-8, Baud-32 - 96 bits/s

Orthogonal frequency-division multiplexing (OFDM) and multiple channel 'Quick Config' buttons are still under development/testing!
