How to modulate one waveform/track with another to achieve FM(Freq. Modulation)?
or how to gen. two chanel FM sine signal 180deg in phase shift (carier and signal)?

I look in Audacity(plug-in) for best quality of waveform but there are no posibility
because as I know now .ny plugins work only with one track

Did you mean FSK data transfer:

Or something like the 1-wire Raspberry Pi FM Radio transmitter modulation encoder:

The modulation Math is fairly trivial:
