The FT of 50000 cycles of a sine wave is much clearer than the FT of one
cycle of a sine wave, no? This is the logic that led me to think that
timestretching a signal may improve FT results, would you mind explaining a
bit more about why this won't work Jerry?

Time stretching doesn't add new information, it just duplicates
existing information. 50 copies of the first page of a book
is usually far less informative than 50 non-duplicated pages.

What looks cleaner from your FT might just be an artifact of
the assumptions you made in creating 49999 duplicate cycles
from the 1 cycle of actual information.

IMHO. YMMV.
