I'm not to sure how to phrase this but, is there a shareware program available that will show you all or most of the available frequencies in songs or audio? I have a certain song I want to see just how low this synth organ goes down to? Someone once told me 16Hz but it doesn't sound like it. The song is "Tocata" on the "Bach Busters" CD distributed by Telarc. I'm not even sure if this is in the correct forum.
