Can't convert DTS-HD MA 96k without downsampling to 24k 2017-06-04 13:51:58 I don't know if this is the right place or the right audience, but fingers crossed and apologies if not (long time reader, 1st time posting ).I have a BluRay Audio (BD-A) extraction (currently an .mkv) where the audio is in 6-channel (5.1) DTS-HD MA, 96k/24bit. However, all the tools I have at hand (ffmpeg, ffprobe, MakeMKV, mediainfo, Kodi (all on Linux)) report the audio stream as DTS-HD MA 48k. However, if I use Kodi over HDMI to pass this to my processor (which does *all* formats), the pre-pro sees it as 5.1 DTS-HD MA 96k! (which is what I was expecting) (I read somewhere that the "core" details are what get reported when you query the container, but the core and "HD" extension streams inside the container gets decoded together and that's what actually gets played by the processor (hence the processor displays the 96k details).Usually, there is an LPCM stream on the disc so at this point, I copy the LPCM 24bit/96k stream using the ffmpeg option -acodec pcm_s24le into a WAV container. If I attempt to do this from the DTS-HD MA stream (which is the only one on this disc), I was expecting it to decode the 96k DTS-HD MA steam into RAW PCM and then write this as a 24bit/96k LPCM stream into the WAV container. However, what seems to happen is, it extracts the "Core" DTS stream, which is 24bit/48k and put that into the WAV container instead:Audio: pcm_s24le, 48000 Hz, 5.1, s32, 6912 kb/sIf I use the -acodec copy switch with ffmpeg, I end up with a WAV file container, with the DTS-HD MA stream inside, which reports as 48k, but plays correctly at 96k (according to my processor):Audio: dca (DTS-HD MA), 48000 Hz, 5.1, fltp, 1536 kb/sSo it seems that you can re-package a DTS-HD MA stream into a WAV container, without touching the stream, but you can't "decode" the DTS-HD MA to PCM (which is what the processor is doing), and store the PCM (inside a WAV container), and keep the lossless 96k part of the stream!?Usually, once I have the WAV with PCM or LPCM, I go on to convert it to FLAC, for storage and tagging purposes, but that's not actually relevant to this problem.Any ideas, anyone?Cheers,Matt.
