Help me, Blogosphere…

…you’re my only hope.

While I’m the mack-daddy of image formats (wanna know the dif between LZW compression, and GIF compression? Just ask), I am largely ignorant of the intricacies of audio manipulation. So I call to you, blogosphere: I have a WAV file of my blog presentation that I gave this morning, and I’d love to equalize the volume…it was recorded on a stationary mic, while I moved around. Thus, it fades sometimes, and I’d love to normalize the volume. Any open/free tools out there that anyone would recommend for VERY basic sorts of audio editing?
