How to process sound from a microphone on the fly in OS X?

Question

macOS

I do live broadcasts.
I'm using OSX 10.10.
What I don't like about my recordings:
1) I hear clicks and keystrokes from the keyboard. Barely audible, but noticeable in silence.
2) there is a slight hiss of the microphone. Which is heard in silence at maximum volume.
3) make the voice bass or high. Just play
around I found only software for changing the voice of a male to a female. But there is no normal equalizer.

With SoundFlower, you can intercept streams and process them.
