Depending on what your planned use is, there might be some useful audio in the Planetary Radio show on the Spirit landing here:

http://www.planetary.org/audio/pr20040126.htmlThe Spirit stuff is not quite up to our usual recording standard though, because the audio was actually recorded at a live event, so there's various audience noises and local commentary going on. I'm checking with the show's producer to see if he has any other audio materials handy from either Spirit or Opportunity. The two local voices are Bruce Betts (a Planetary Society person) and Donna Shirley (was responsible for Sojourner).
