Just for removing the start of a track (eg the voice on some bird call CDs)
I have been using mp3tfrim which is small and fast (and free) but must try
Audacity

Interesting comments Dean!
I use Audacity to move taped birdcalls into my computer (to .WAV files).
As
you say it is a free program which I have found both easy and a joy to
use.
As well as editing out the voice component, I also found it great for
editing out the various clicks, pops and other extraneous sounds on the
tapes. There are other commercial sound editing programs around but I
think
Audacity is quite adequate for bird calls.
Dean, I assume you used amplified speakers, which ones did you use?
Another quite cute arrangement I experienced was a guy who used his mobile
phone with MP3 on board, he simply used the phone's speaker which sounded
quite loud.
The last comment I would make is that all MP3 and iPods use "lossy"
compressed formats that remove sounds, possibly audable to birds, but
inaudable to the human ear to achieve compression. Doesn't worry us for
verification purposes but may effect callback.
