I know, but ffmpeg is the only DTS encoder I have on my Mac. So, no big
choice.

Thanks you! I have tried both of your suggestions. Both of them are
looking very promising, because I will get a WAV file that I can import
into iTunes and gives me this "dts noise". I can not test if it decodes
this noise on my Denon receiver this week, but will do next week. The
only difference is, VLC is not able to play the generated WAV. VLC kind
of crashes if I open that WAV file.
Output with FLAC file:

I've also tried to generate an AIFF file instead of WAV, because iTunes
does not allow me to add a cover picture to WAV files. But it seems
there is a reason for WAV, VLC plays the AIFF as AIFF and not as DTS.
But anyway, the WAV result looks very promising now. Thanks!
