The code available here corresponds to my preamplifer output: as I do not have a level limiter on my amp, the output signal from the preamp is not very loud. So the "sensibility" is defined to 16...

If the level is too low or too high, you just have two lines of code to tune.

Anyway, I use a cable with RCA connectors, plugged behind my preamp.

When the system has started:

• press the momentary button connected to RX0 to select visualisation
• press the momentary button connected to TX1 to select sensitivity between -4 to 16
