No need to pay for software (though it couldn't hurt.)
Just spend a couple of nights running songs of various genres through a 1/3rd or 2/3rds octave graphic EQ and start systematically playing with the bands, one band at a time, up and down, *really listening*, until you get to recognize which "sounds" and which attributes are associated with which frequencies.
Start now, and by Super Bowl you'll be able to tell that when Wally Ogumleye sacks Peyton Manning, that there's a definite 2-3kHz sound of Manning's helmet cracking combined with the wind of the the air coming out of his lungs that starts as a 4kHz wheeze and rapidly modulates down to low 500Hz "Unnnnnh" sound.
