Program to find peak frequencies?

[ShagggDiesel 25]

Alright well to start, I'm an experienced music producer/recording engineer. I'm starting to incorporate my music into my car audio hobby. I've been making a few bass tracks to test out and demo with in my car. My question: What's a good program to use to find peak frequencies in a song? I'm going to start finding this out in my bass songs and posting them up here on the forum for people to use and test out. Also, I'd like some feedback, and maybe videos of people using them.

Audacity works well

Ok I've got audacity downloaded, where do I go about from there to find what I'm looking for? Obviously have the song imported to the session.. but then what?

select 23.8 seconds of the track anywhere you want to check or select as much as you want and it will narrow it down to the first 23.8 seconds of the selection. Then go to analyze and plot spectrum. Then change linear frequency to log frequency. then change 512 to 16384.
