I am planning to buy a sub-woofer and I want to create a CD with low frequency content for evaluating sub woofers in the stores. I want to analyse my CDs (or ripped content) to find which tracks have the lowest frequency content. Is there a software that can do this easily?

Another alternative to Audacity is to use Spectrum Lab. This one is intended to be used as a real-time spectrum analyzer. It listens to the soundcard input and produces spectral analysis and spectragrams of that signal in real time.It's a little funny get get setup. I had a little trouble the first time I used it...I could barely figure out how to get it to start running.
But, once you figure out how to get it to go and how to show the frequencies that you are interested in, it runs like a rock. It's pretty impressive.
The Ham radio guys love it for looking at base-banded signals. I think that that was its original purpose. I use it exclusively for audio analysis.

Hi,Audacity is a freeware application that does audio editing and recording. If you have a list of possible songs that you're interested in testing, you can rip them to wavs and then open them in Audacity. You can use frequency analysis (FFT) or use can switch the view from waveform to spectragram.
Audacity is a cross-platform app, so you can use it on Windows or on Mac.
It's not as friendly as Cool Edit Pro, but it is free.

A few years ago this magazine published a list of CDs that had deep bass. I don't have it anymore but it looks like they sell back issues.
Vol. VI, No. 3—"Low Bass on CDs—How Low Can You Go?"
Audition 1.5 (now 2.0) is good. If you can buy the old version 2nd hand, that would be good. Otherwise do a seatch for free spectrum analysers. Most of these including RMAA are not good. In particular RMAA gives wrong numbers in the analysis.
Just use Windows Media Player or Winamp, they all have spectrum plugin.
To have a little better idea I would suggest Adobe Audition (formerly Cool Edit Pro). There is also lots of shareware that can help you too.
