HI all . I'm trying to analyse the electric signal emited by a fish called " gnathonémus ". I put 3 electrodes in the aquarius ( 1 for the ground and 2 for hot point ) , and plugged it into my sound card . My pd file put the adc~ object into an env~ so i get something like the intensity of the signal ( am i wrong ?) . What i need is to separate the frequences , phase , and intensity from the raw signal : is there object that can do such stuff ? Thanks 3o3

ok ;)

perfectly right (though intensity is probably not as well defined as amplitude)
What i need is to separate the frequences , phase , and intensity from the raw signal : is there object that can do such stuff ?
