I just found this thread after recording about an hour of voiceover and driving myself crazy trying to reduce my clicks. I do a lot of narration that then gets sent to a producer for cleanup and final production. But it's annoying and embarrassing to send out a file filled with clicks! So I end up doing a fair amount of manual cleanup before i send it out. I've tried several filters in Audacity,but so far, no magic bullet.
I do find that the granny smith apple idea works pretty well, at least for a few minutes into recording. But the discussion about better articulation is interesting. I've found that the more I articulate, the more clicks I hear. Perhaps because the tongue is working hard to be clear, and that can cause some freezing up or something. But I'll play with that further.
I also find that if I can humidify my studio before I start, that helps a lot, too -- just using a room humidifer. Obviously can't leave it on for recording, so the usefulness is limited. But that also reminds me that this problem seems worse in the dry winter months.
Thanks for all the ideas! MT
