"FFT bin index" doesn't show.

January 14, 2011 | 4:17 pm

I'm tried FFT analyze with pfft~.
But in the sub-patch,FFT bin index number doesn't appear from the 3rd outlet of the fftin~.

The patch is not complex system.It's nearly basic FFT patch.

What's bringing about?

Please,give me the solution.

the index bin should appear from the right outlet of [fftin~]
you could use the [count~] object instead.
Could you show the whole pfft~ patch so it is easier to find a solution?

i see you connect the fftin~ outlet of the bin index, first to a [number~]. i think that the [number~] when used at the "~" state, does not send out the received values, so there migt be your problem. bypass it and see if it works!

Thank you,Nikolas.
I tried to bypass the [number~],but it doesn’t go well.

And I show the pfft~ patch again.(it’s still under construct)

The "top [number~]","second [number~]",and "[float box] under the [snapshot~]",all objects are showing "0.".
It means that 3rd outlet of fftin~ doesn’t put out any signal?

Or I’m misunderstanding something?
