Submitted Question:
"We have attempted to use Adobe Visual Communicator but
are having audio problems. We have tried two different camcorders (Canon GL2
and Canon ZR40). We have tried a couple of different microphones including a
wireless condensor mic with an internal battery."
Have you connected the microphone directly to the camera (not the soundcard or mic jack on the PC)? The preferred method of connecting microphones (or mic mixers if using multiple mics) is to feed them into your camera's mic input jack. Then within Visual Communicator, you need to choose the camera as the mic input device. Go to the setup tab, choose audio, and dropdown the listing and choose the camera.
Also make sure your camera is set to 16-bit audio, as 12-bit makes you sound like chipmunks high pitched (see episode 9 for more on this).
Make sure that battery is still good on the mic you mentioned too...
Hope that helps, let me know below with comments or additional questions.
