Seems is like ProjectX work .
I don't know a tool than work at this level with DVB-T2 captures (TS container also?)
My XORO receiver saves the clips in an MTS container. But I usually process it first with TSDoctor which converts it into TS.

The weird thing is that these audio dropouts are present in the recorded MTS file, but watching the TV content directly then I hear no dropouts. I use the analog TV input so the receiver has to decode audio to analog on the fly. Looks like the receiver tries to repair the dropouts in this case, but not when playing the recorded file.

There are some tools inside editors than can help (Click Removal in Audacity, etc.), but not always 100% accurate.
Since I always convert audio to WAV first (for cutting in StaxRip via VDubMod) this would probably be my workflow. I do have a couple of WAV editors (WaveLab, Audacity, Acoustica, Adobe Audition) installed plus some older VST plugin packs (mainly the Waves plugins), but so far the declickers have not worked for these dropouts. The closest I got so far was automatic silence detection, then manually fix the glitches. But this does take a lot of time...
