I am try to boost frequency from an adc~ input. I've tried +~ a number or adding an osc~ object to achieve this, but have only boosted gain or heard an oscillator over the microphone, not the signals being combined. I am kind of new to PD and am more used to traditional programming language so any help will be appreciated.

boost frequency? you mean you want a low pitch to sound higher?

there's no simple arithmetic way to do that. but, if you search for 'pitchshifter' that may help. 'realtime phase vocoder' may also help.

maybe split the signal in to directions, one goes through a bandpass filter [bp~] and is then added to the original, that should be like a 1 band graphic equalizer. that might work

It might depend on what interface you are using or if you are plugging the mic straight in without an interface maybe you should go to you sound preferences and increase the input levels

Thank you, I will look into all of those ideas, and the idea is to make a lower pitch very high.

Maybe simply multipy it using this *~
