I find S.E.T.I. interesting, and I was wondering if SETI@home uses only
audio for the search of Extrateresstrial Intelligence. If so, would there be
a program on the internet available for public download similar to SETI@home
except instead of the program searching for audio results would this similar
program search for objects. Searching objects as in comets, meteriods,
spacecraft and space debri.
Thanks in advance,

SETI scans through radio waves, not audio. Comets would require optical
observations, as they're electromagnetically inactive for the most part.
Meteorites are by definition matter that reaches the Earth's surface and
they're usually fairly obvious and it would be too late. Spacecraft and
debris would be best found with radar due to their metal components.
This would require and active source producing radar siganls first and a
receiver to go with it. NASA already operates the Deep Space Network for
these kind of tasks. SETI is entirely passive and only receives signals
at Arecibo.
