Andreas Eversberg 4356c93afa common: Add pre and de emphasis, if the radio does not support it 
Connect to the oscillator of the transmitter - good girl!
You need to enable pre emphasis in this case.

Connect to the discriminator of the receiver - good boy!
You need to enable de emphasis in this case.

Andreas Eversberg 1146537d84 common code: Add feature to record received audio and replay it 
-W <file.wav> writes a wave file of received audio
-R <file.wav> reads a wave file to feed into decoder

This way you can record a phone and later debug without a phone
and radio equipment.
