Trouble with clicking in audio

Can anyone give me insight into where this clicking sound is coming from in the following audio whenever the monk speaks? These are originally orphaned .MTS files brought into FCPX 10.1.3 and exported out as .mp4 files then uploaded to YouTube. The clicking is not heard on the original files:

Thanks for any insights.

It corresponds with audio peaks and pops. Put a compressor or limiter on it.

I have the same problem. My topic : Sound clicking after Transcoding with FCPX 18 Nov 2014 19:23 #56164

IMO a comp/lim won't sort it, it sounds more like an issue with the way the file has been compressed.

Did you upload directly to Youtube from FCPX or did you render it to a file first?

You can also hear a mobile phone interfering with the audio as well, should have used balanced mic cables ...
