Maybe the problem is your Audacity decoders.
I decoded the compressed formats (out of Audacity) to wavs, and only load in Audacity decompressed wav files.

I decoded the DTS with eac3to using libdcadec and ArcSoft and both show the same problem. The AC3 decoded with eac3to libav.

Try using that method because your DTS spectrogram seems limited to 300 Hz, but mine go until 3000 Hz and more, and I don't see problems with AC3 spectrogram (like you show in video) also until 3000 Hz.

EDIT:
Using my Audacity decoders (ffmpeg-win-2.2.2), both spectrograms go until 3000 Hz but seems fine:
The DTS don't have high harmonics and the AC3 is equal to the DTS without the problems in your video.
