Sampling from an audio track

What I want to do is :
Having loaded my own audio file to be able to take N equally spaced samples over a small time interval from a portion of the file and to be able to load the samples into another program-say eg Xcel- in order to further analyse them. Can this be done using Audacity?
I would appreciate any advice or directions in order to achieve this.

This is similar to the solution I wrote for another poster who also wanted to cut down a large sound file.


Thanks Koz, will give it a try.
