Removing Audio Filters and Keyframes
I believe that it is safe to say that we have all started down a definite path with a given project and at some point have decided to change direction. If you want to try something drastically different, I would create a duplicate sequence that you could go back to if it doesn't work out. If you've made a ton of changes to the audio via filters and keyframes that just aren't working out, their is a quick way to get back to sqaure one.

Removing All Audio Filters and Keyframes from your Sequence
1 Select all of the audio clips in your sequence.
2 If you have a two button mouse, right click one of the selected audio clips and select Remove Attributes from the menu. If you are using a one button mouse, you will have to control click to get to this menu.
3 Within the Remove Attributes menu choose Levels, Pan and Filters, then click OK.
