As for an example, if you wish to transmit the audio file "cq.wav" (sampled at 11025Hz) on 145.500MHz with a standard 5kHz deviation and no frequency correction, no subtone, you can simply type:
./nbfm.out cq.wav 145.5
Another example, using a subaudio tone:
./nbfm.out cq.wav 145.5 11025 -15 5 400 0.01 110.9
It means to transmit on 145.500Mhz the audio file "cq.wav" sampled at 11025Hz, applying a carrier frequency correction of -15ppM, FM deviation of 5kHz, 400us pre-emphasys, adding a 110.9Hz tone with 1% of full scale level.
