I've been assigned 2_01_01 where the Ork is introduced. The voice of the Ork is great, but there's alot of "popping" (not sure of the word) on the p sounds. Should we still animate to these? Will they be replaced or not?

Animate to what you have. (However, Mark is still rigging the Ork, so animate the other characters first.)

I managed to edit them out with Audacity using the fade out and equalization filters. For EQ, just highlight the offending section and this is the curve I used.

For future reference, anybody who's recording voice tracks:

The place to put a microphone where it won't pop is just above the mouth and to the side of the nose, so if you lean forward it will hit the root of your eye tooth. If you're reading a script and you look down a little, it should block the vision in one eye.

It may not be possible to switch to this position now, since the sound will change vis-a-vis existing tracks. On the other hand, it may be worth looping. The EQ curve Ken showed is going to seriously thin out the voice and still won't completely eliminate pops. You may not hear them in your monitor speakers, but if this goes into theatrical release you'll hear them then, when it will be too late - and so will everybody else.

An old "poor musician's" trick for a homade 'pop' filter:

Get a wire hanger, you can still get one from a dry cleaner, and old pair of panty hose. Straighten and rework the hanger into about a 10" circle with the hook coming down. Cut off and slip one leg of the panty hose over the hoop. You want the nylon to be reasonably tight over the hoop. Use the "stem" to bend and position the circle between your mouth and an inch or two in front of the mic . The sound vibrations go through but the air stream that causes the pop is dispersed by the mesh. (I have successfully used duct tape to hold and position the filter to the mic stand)
