[Scilab-users] PolyPhase (chanelized) FFT

[TViT]

Has seen demo - Atoms Time Frequency Toolbox (STFTB).
I want to construct such beautiful spectrum recorded human voice - words,
only with the high frequency resolution by method polyphase FFT 
https://casper.berkeley.edu/wiki/The_Polyphase_Filter_Bank_Technique
<https://casper.berkeley.edu/wiki/The_Polyphase_Filter_Bank_Technique>  .
Has written a code, but my knowledge have allowed me to write only such
code, as more - I do not know. 
Help please, or sources to realisation polyphase FFT in Scilab...

My code:
