Hello All,
the example (from manual) for pvsftw is:

ifn     ftgen      0,0,inbins,10,1        ; make ftable
kflag   pvsftw     fsrc,ifn          ; export  amps to table,
kamp    init       0

if      kflag==0   kgoto contin   ; only proc when frame is ready
; kill lowest bins, for obvious effect
        tablew      kamp,1,ifn
        tablew      kamp,2,ifn
        tablew      kamp,3,ifn
        tablew      kamp,4,ifn
; read modified data back to fsrc
        pvsftr      fsrc,ifn
contin:
; and resynth
aout    pvsynth    fsrc

If i'm not wrong here we write a table with amp value
setting first 4 index to zero.
My question is: why don't set to zero table index 0 too?
Is 0 index amp of 0 Hz, the first bin?
And this don't affect dc offset?
Also: what is the *obvious effect*?

Please apologies if stupid question or if totally wrong.

Thanks,
ciao
francesco.
