Description
In Media Center 31 for Windows, we made it possible to bitstream compressed audio formats from audio-only files, including Dolby Atmos music.

This should work for the usual bitstreaming codecs, AC3 & E-AC3, DTS (including HD versions), and TrueHD - as well as Atmos extensions for TrueHD and E-AC3.

Instructions
You can enable bitstreaming in the Settings, under Audio -> Settings -> Bitstreaming, and either select a preset for how your audio receiver is hooked up, or enable individual codecs in the Custom section.

Invididual Codec selection for object based audio like ATMOS / DTS-X would be great to add.

Thank you! Much appreciated.

Will you ever bitstream NATIVE DSD or only DoP?

Will you ever bitstream NATIVE DSD or only DoP?

Native DSD can already be bitstreamed. It is an option in Audio. It requires a ASIO driver.

[Awesome Donkey]

Yeah, Media Center has supported native DSD via bitstreaming for years now on both Windows and Linux. As mentioned by dtc it requires a DAC that supports native DSD on Windows and it requires a ASIO driver from the manufacturer. On Linux it requires support in the Linux kernel for your DAC.

macOS only supports DoP (except there is a few DACs with either a custom ASIO driver for macOS or it has a special app feature to 'convert' DoP to native DSD) though.

[mlknez]

I should have been more clear... I meant native bitstreamed over HDMI.  I can do it just fine over USB/ASIO.  Currently, the only DSD bitstream choice over HDMI is DoP.

[dtc]

Native DSD cannot be sent over HDMI on a PC because their is no support for that format in the current implementations of HDMI on PCs.  It is part of the HDMI spec, but the graphics companies have just not implemented it.  It is a long-time problem and it is doubtful it will change. It is just not a priority for the companies making the cards.

[Awesome Donkey]

Yeah, DSD via HDMI from any sort of computer is likely not ever happening unfortunately. I don't see Nvidia, AMD, Intel, Apple, etc. adding support for it in their GPU drivers, like ever.

And it isn't a Media Center limitation and there's no way support for it can be added via any media player. It'd literally have to be supported by the GPU manufacturers in their drivers and honestly at this point hell likely has a better chance at freezing over. Or Nvidia supporting 3D again, heh. Anyways, DSD over HDMI only works with SACD disc players connected via HDMI to receivers, for example.

GREAT NEWS, Hendrik!

I'm doing some tests using MKA audios files with ATMOS and MC plays them nicely.

But there's one thing that could be improved: gapless audio albums, like Dark Side of the Moon, by Pink Floyd.

I ripped individuals MKA files from the BD, but JRiver plays them with a little gap between each track.

I tried ripping it to a single MKA file. The file plays gapless and I can skip the tracks of the album (YEAH!!!), But MC library shows only a single file, not each track separately.

So, I made a .CUE file from the single MKA, imported it and the tracks were shown seperately in the library (DOUBLE YEAHS!!). Unfortunatelly, MC goes "crazy" when the tracks are skipped, jumping to about 5 seconds after the beggining of the track.

Is there anything that could be done to solve this?

[Manmcg]

Any likelihood that this will come to Mac Media Center 31 ?

Probably not.

i just ripped John Williams Live in Vienna Atmos from my backup to individual MKAs for each track.  So far the bitstreaming is working fine, however I had a suspicion gapless would be an issue.  Time to try DSOtM.

might particles be an option here instead of a cue sheet?  I experimented with particles in the past from MKVs and even full backups, but the gaps made a lot of my music unusable.   Not sure if anything has changed here so will experiment.


EDIT:

Particles don't work either.  Near the end of one particle it starts to play back the next in the list causing about 5s of loss of the current track being played.

EDIT 2:

CUE file produces the same results.

[aydin]

Probably not.

Because?

Also is it possible (on JRiver Windows) to convert DTS, TrueHD and MKV Surround files to WAV/AIFF files?

I want to import them into professional applications that only support WAV/AIFF.

[jmone]

Because?

It's built on a set of Windows Libraries (LAV Filters).

Also is it possible (on JRiver Windows) to convert DTS, TrueHD and MKV Surround files to WAV/AIFF files?

Sure - see the attached screen shot of what is supported for converting audio from Video Files to standalone audio. 

[maid]

I am confused about this part
Instructions

Can someone help explain this to me

[leperlord]

Great infos here
