Ok found this :
https://forum.arduino.cc/t/arduino-rtty-decoder/82177
Now i do FFT is being used there, it is utilized to remove the margin pulse of volume (AKA noises).

Hi,
Sorry if i missing something in the translation, but where FFT is fitting here ? and why do you need it ? if (big if here) you are trying to decode.
See, FFT will be needed to display a continuous line from points and this is most relevant situation i can think of that you might need an FFT poccessing.
Otherwise, the decoding of RTTY is identical to bit signals like DialUp modem...
