MakeMKV will load the file and use it to decode DTS-HD audio. You need to obtain a copy of dtsdecoderdll.dll and set it's location in MakeMKV preferences on "Advanced" tab. The fact that this DLL is a Windows 32-bit DLL doesn't matter.
DTS DECODER M6 MAC OS X
With this DLL, DTS-HD decoding will work on all platforms - Windows, Mac OS X and Linux, 32-bit and 64-bit.

Please don't be confused - MakeMKV only uses this DLL as "algorithm reference". In order to decode DTS-HD, MakeMKV needs a so-called reference decoder DLL. Unfortunately, MakeMKV still needs an external decoder to decode DTS-HD and a one-time setup is required. More details about MakeMKV audio transcoding capabilities may be found on our forum. Starting from version 1.7.5 MakeMKV can decode DTS-HD audio streams and save them in any supported format (LPCM, FLAC, etc). Just remember who brought it to you in a first place. It was a good run, for 10 years mmdtsdec was the only open solution to decode all DTS streams and for a few years it was the only open solution for DTS-HD Master Audio decoding (on all platforms!).

DTS DECODER M6 CODE
With this change mmdtsdec code is finally retired for good. The information below is outdated and is preserved only for historical reasons.Īpril 2018 UPDATE: Starting from version 1.12.1 MakeMKV uses ffmpeg DTS decoder which supports all codecs, including DTS-HD LBR (XSA). July 2015 UPDATE: Starting from version 1.9.3 MakeMKV uses an open source DTS-HD decoding library without the need for any additional files. The most common application is DTS-HD Master Audio - a lossless codec that is used on many blu-ray discs. DTS-HD is a family of proprietary audio codecs.
