a hope for dts-ma decoding?

i have to ask.... is there any possibility there ever will be a dts-ma decoder?

my computer only got SPDIF output and that is fine by me.. i got a great 2.0 setup. so what i need is dts-ma decoding and downmix..


is there people working on dts-ma decoding??

FFDShow can decode the DTS core and downmix it to 2.0
The Arcsoft decoder can decode the full lossless audio but you need to use your soundcard's analog output (if it has 24-bit DAC) or LPCM connection through HDMI 1.3+

No, I mean decoding with the Arcsoft decoder. You can use the TMT player itself or you can use the TMT2 (or TMT3 with some tricks) decoders in MPC-HC.
The "Arcsoft Audio Decoder HD" can decode DTS-HD MA tracks and send the 24-bit PCM signal to a compatible soundcard or external DAC.

well the only way i got it working was with eac3to and code it to FLAC.... but i gave TMT5 a test now and it seems ok but i don't know if i get DTS Core or DTS MA.

but if i use tmt2/tmt3 dll's in mpc-hc there is no way to downmix to 2.0? only decode 5.1 (source) and play it back over HDMI? i got a high-end sound card and a Naim 2.0 stereo with a GREAT DAC.. but then i first need the down-mix on my computer to get it working over Optical S/PDIF.


i could give it a try with tmt3 and see what i can find on my own.. but do you know any guide to get tmt3 dll's working with mpc-hc? or what version to use? (mostly the version is important..

These are the steps I used to get it working on my pc:

1. get ffdshow and arcsoft tmt 3. update tmt 3 to v. 3.0.1.185
2. get the checkactivate.dll from http://forum.doom9.org/attachment.ph...7&d=1271603449
3.search the arcsoft folder for asaudiohd.ax and add the checkactivate.dll to that subfolder.
4. register asaudiohd.ax
5. Open up mpc hc, go to options, and then external filters. Add both the ffdshow audio decoder and the Arcsoft HD audio decoder, and set them both to prefer. Make sure ffdshow is above arcsoft.
6. Open up ffdshow audio decoder configuration, go to codecs, and select disabled as the decoder for DTS. Step 5 and this step ensure ffdshow will be used for truehd, but not for DTS or DTS HD.
7. Open up C:\Windows\win.ini. Add
Code:
[HKEY_LOCAL_MACHINE\SOFTWARE\ArcSoft\MPEG Codec\Decoder Setting\]
AudioOutputMode=17
AudioDynamicRange=0
8. Change the audio output mode number to match your speaker config.
Code:
0,1,2,5: Stereo
6,13: 5.1 Channels
17: 7.1 Channels
16: S/PDIF
9. Open mpc-hc.exe in a hex editor (i recommend HxD) and replace the two occurences of the hex string "33806DE046DBCF11B4D100805F6CBBEA" with "578F49F699B3434AA6FAF694AD42B9BE" in the file and save. Remember to redo this if you ever install a new version of the player.

That's basically all the information from the arcsoft codec unlocker thread summed up into one post.

you can just type in win.ini into the start menu search, and it should come up.

oh, you shouldn't use haali.
the hex editing step is meant to modify the mpc hc internal mpeg splitter.

so if you are using another splitter entirely,well, you can see the problem.
