[PD] pitch extraction help

[cristiano listas]

hello list,

i'm trying to extract pitch from audio signal (sampled or streamed, but the
extraction has to be in real-time).

In this patch i tried to filter the amplitude of the signal before send to
fiddle~. In fact, amplitudes outside of 83 - 86 register will cut
the fiddle~~recognition with the message [auto 0].

Is not working properly. Ideas?

Thank's
