Using a window inplies a FIR filter. Start with the fir1 function to design it, and freqz to analyse it. Filter your signal with the filtfilt function.

a .wav file is an audio file, so use audioread to import it.

I can not utilize the givin data in the Fir1 filter . To get N or Rp or Rst

I have no idea what problem you are having, or what your constraints are.

You described a FIR filter design that should be straightforward to implement.
