frequency-analysis

Just wondering if it's possible to go through a flac, mp3, wav, etc file and edit portions, or the entire file by removing sections based on a specific frequency range?

So for example, I have a recording of a friend reciting a poem with a few percussion instruments in the background. Could I write a C program that goes through the entire file and cuts out everything except the vocals (human voice frequency ranges from 85-255 Hz, from what I've been reading)?

Thanks in advance for any ideas!
