Hello to all on the list.
I am trying to create the follow on PD:
PD would capture sound through adc~ (sound that would be from one or several microphones), from these sounds I would like to limit their processing accourding to a specific range of frequencies , say with fiddle~ maybe (actually I would like to try and limit them to just voices, altought I know that is dificult to do)?
From that the specific interval that PD would process by apply different filters or passes and output a sound response in what would be an abstract form of response from the converstaion or voice that were being captured.
My doubts and difficulites so far are:
How do I specify to fiddle~ a specific range of frequencies?
The unpack object when connected to one of the pitch outlets from fiddle~, can show the raw pitch and amplitude. Can I use this to indicate to sig~ the sounds to process?
Finally if by connecting the numbers that are produced by fiddle~to sig, why is it that I just get a sound resembling interference (like if someone was tapping a microfone), instead of actual sound reprodution?
I thank advance anyone who can give me a hand on the this.
Cheers Joao

You don't. But you can process the output of fiddle~ in any way you wish. There, you can use only the ranges you need.

not sure what you mean... but... you can use that information in any way you wish. You will most likely use those as control messages so [sig~] will perhaps not be necessary.

[sig~] is simply a float to signal converter for the objects that need a signal as an input, for example the [osc~] object, when created without arguments. Connect the output from [sig~] to [osc~] (no arguments) and you should hear a sine wave that will follow the raw frequency of your input signal. But you can bypass [sig~] and connect directly to [osc~ arg] (where "arg" is any float) and you should get the same behaviour.
like: <some-number> -> [sig~] -> [osc~] -> [dac~] or <some-number> -> [osc~ 220] -> [dac~]
HTH.
