  Vibe is a small python executable to send image thru sound (by BimBim134)

I created a digital mode ! My little program can send and decode small pictures using QPSK modulation. The message is 27s long and in the 300-3000Hz range so it can be transmitted using lots of different gear (at least, it was design to). The center frequency is 1800Hz.

  2 93 4.5 C++

  Simple OFDM modem for transceiving datagrams

  

I've put a limit of a million (1000x1000) pixels, to keep memory and CPU requirements practical for the Android apps but the modem is only concerned with sending 5380 bytes. You could plug in your larger numbers and see if it works for you. You can find the modem code here: https://github.com/aicodix/modem
