  1. Any help here appreciated.

    I was given several albums ripped from Bluray which are supposed to be DTS-HD MA 5.1 files converted to FLAC.

    Forgive my ignorance but is there anyway of checking the FLAC files to see whether they are rips of the full DTS-HD MA audio or simply rips of the core?

    Thanks

  2. There isn't any direct way to find out. Maybe an expert can identify lossy encoding artifacts in the audio (spectrum).

  3. Thanks - nothing I can spot using Mediainfo etc then?

  4. Correct. (Unless the ripping software somehow tagged the files with this info. But it is unlikely.)

    Maybe look at the spectrum with a program like Spek to look for the higher frequencies being abruptly cut off.

    That's only applicable if you are sure the source file(s) were not already filtered in the same such way.
    Only way to be sure of that is if you HAVE the source files, or some spectrum printouts.

    DTS Core is limited to 24 kHz waveform, so if you find higher frequencies, you have HD. The converse is true only if you know that the original had a sample rate higher than 48 kHz.
