It depends on what kind of audio you want to record. A tie clip is good in noisy areas and you want to make sure you get a clear recording of someones voice, examples are wedding speeches, exchanging of vows, a politician promising the sun, moon and stars if you'll vote for him/her... but as Mark says a shotgun mic might be better as is can be used to pick out sounds at a distance and it can also be used to record interviews. If you camcorder doesn't have a hotshoe, then go along to your local music store and see if they have any mic stands, so you don't have to handle it as much when recording.
