Noise Vocoder not working properly

Hey guys, can anyone let me know why this setup isn't working? I'm basically making a noise vocoder, mic input passes through reson~ then to a live meter to get their current amplitude and then a noise generator generating the same reson~ according to the amplitude of the current signal.

[meter~] does not output a value in dBs, but a peak value. Try getting rid of the [dbtoa] objects.

The patch still doesn't work, I actually added [dbtoa] only to double check if without it was the problem.

Basically I made a simpler version in the lower right and it seems that [reson~] doesn't let any signal pass through in rnbo~

It would be helpful even if someone said "No it should work idk whats wrong with it"

Hi Jim,

Don't know if you found the solution already, but the problem was your first value of reson~. The object accepts 2 values: center frequency and resonance value. For some reason, you gave it 3 values, all your resonators were given a center frequency of 1Hz. When you remove those values, your patch works.
