ArcSoft TotalMedia Theatre build 113 Trial: http://www.arcsoft.com/support/downl...downloadid=384 can decode DTS-HD MA including DTS-HD MA 7.1 channels using GraphEdit: FileSource (Async.) -> ArcSoft MPEG Demuxer -> ArcSoft Audio Decoder HD -> Dump.ax still doing tests, but initial results look very promising, i.e. decodes are bit-perfect. |

Just a quick question. When converting DTS to AC3, using eac3to and the Sonic Audio Decoder (which takes about 9 minutes), I see only 1 of my 4 cores is being used. Does eac3to have a multi-threaded switch by any chance? I couldn't find any. Or maybe the Sonic Audio Decoder is not muti-threaded?
Thanks

It seems xkodi is right.
Did some tests also and: 1. Arcosoft decoder decodes the full DTS-HD info 2. It can output 7.1ch 24bit I used The Orphanage Blu-ray with 7.1 DTS-HD Master Audio sound and i got 7.1 channels using xkodi's graph. When I set the decoder to 5.1 ch, I got bit identical results with Sonic decoder (except from some garbage data at the beginning). Below are screenshots from the 2 decoders (5.1 sonic and 7.1 arcsoft). Last edited by nautilus7; 10th June 2008 at 00:32. |

1) DTS-HD MA, 5.1 channels, 24bits, 48kHz: ArcSoft decodes identical to Sonic, i.e. bit-perfect 2) DTS-HD MA, 5.0 channels, 24bits, 96kHz: ArcSoft decodes as 5.1 channel WAV with silent (all bytes are zero) LFE channel, other 5 channels identical to Sonic, i.e. again it is bit-perfect 3) DTS-HD MA, 5.1 channels, 16bits, 48kHz: ArcSoft decodes always as 24bit, but LSB is not zero, when convert to 16bit with Wavewizard 0.54b it is identical to Sonic. however, because of the rounding error during the 24bit->16bit conversion some byte are greater or lesser with 1 than the corresponding reference byte from the Sonic decode, but still it is it is bit-perfect decode 4) DTS-HD MA, 7.1 channels, 24bits, 48kHz: ArcSoft decodes all 7.1 channels, first 6 channels are identical to the 6 channels decoded by Sonic, so we can assume that the channel 7 and 8 are decoded also bit-perfect, but it is not a proof for that we need good sample like Blu-ray with 7.1 LPCM (or TrueHD) for reference and DTS-HD MA 7.1 24bits track to compare against. 5) DTS-HD MA, 7.1 channels, 16bits, 48kHz: "Dragon Tiger Gate" Blu-ray has TrueHD 7.1 track and DTS-HD MA 7.1 16bits track. the six channels decoded by Sonic are identical to the first 6 channels from the TrueHD 7.1 decoded with libav. however, ArcSoft failed to decode the 16bits DTS-HD MA 7.1 track. the result is very strange, because seems like channel 1 and channel 2 are decoded as all zero.

@madshi:
When demuxing a m2ts file (extracting DTS sound of "The Matrix"), eac3to reported a 600000ms offset (10 mins). That seems a bit excessive. I was able to correct it again by specifying a negative -600000ms delay to compensate. But any idea what might have caused this?

@ Asarian
This isn't a studio made blu-ray. You made with tsmuxer, right? It happens all the time with my tsmuxer made m2ts files. I think it's a problem with tsmuxer, so i recommend you ask there. @ ALL When asking something or posting a log or whatever, please say which movie it is and if it's not an original disc say how it was made. It's that someone else has that movie and can test it. Last edited by nautilus7; 10th June 2008 at 12:32. |

today, during the test i found two important properties of ArcSoft Audio HD decoder:
1) when decoding DTS-HD MA, no matter if 16bit or 24bit is selected in the "ArcSoft Audio HD Decoder Setting" the decoder output is always the same and has 24bit 2) for bit-perfect decoding of DTS-HD MA the real number of channels of the DTS track should be selected in "ArcSoft Audio HD Decoder Setting" these two properties along with: 1.1) DTS-HD MA 16bit files are always decoded as 24bit, but LSB is not zero, when convert them to 16bit, the output is bit-perfect with small rounding error (as i mentioned here: http://forum.doom9.org/showthread.ph...67#post1147467) allow us to find out the real parameters (number of channels, bit-depth, sample rate) of the DTS-HD MA track with very simple procedure: - decode the track with eac3to using "Sonic Audio Decoder" and get "DirectShow reports C channels, B bits, Skhz", where S is the real sample rate, B is the real bit-depth and C is the number of channels, but not always the real number, because Sonic do not understand 7.1 channels - decode the track with "ArcSoft Audio HD Decoder" with different settings for number of channels until the first two decoded channels are byte-by-byte identical with the first two channels decoded with the "Sonic Audio Decoder", then this is the real number of channels using this procedure managed to find out the real parameters on most of the samples from "DTS-HD 2008 High Definition Audio Demonstration Blu-ray Disc": 00004.m2ts: (Demo Sample: SFX) : DTS-HD MA, 7.1, 24bit, 96kHz 00005.m2ts (Movie Sample - Night At The Museum) : DTS-HD MA, 5.1, 24bit, 48kHz 00006.m2ts (Movie Sample - Eragon) : DTS-HD MA, 5.1, 24bit, 48kHz 00008.m2ts (Movie Sample - Hairspray) : DTS-HD MA, 7.1, 24bit, 48kHz 00009.m2ts (Movie Sample - Rush Hour 3) : DTS-HD MA, 7.1, 24bit, 48kHz 00010.m2ts (Movie Sample - Nature's Journey I) : DTS-HD MA, 5.0, 24bit, 96kHz 00011.m2ts (Movie Sample - Nature's Journey II) : DTS-HD MA, 5.0, 24bit, 96kHz 00013.m2ts (Music Sample: BT - Dynamic Symmetry) : DTS-HD MA, 7.1, 24bit, 48kHz 00015.m2ts (Music Sample: Pixies - Debaser) : DTS-HD MA, 5.1, 16bit, 48kHz 00016.m2ts (Music Sample: The Who - Pinball Wizard) : DTS-HD MA, 5.1, 16bit, 48kHz 00017.m2ts (Music Sample: Chieli Minucci - Daybreak) : DTS-HD MA, 7.1, 24bit, 48kHz 00022.m2ts: (Demo Sample: Orchestra) : DTS-HD MA, 7.1, 24bit, 96kHz |

Nice tests. Madshi has some job to do...
Did you try any dts-hd hi res tracks? I tried one (5.1, 24bit, 2082 kbps from Testoteron HD DVD), Arcsoft decoded it, but i am not sure what it decoded. Feeding both decoders with the whole dts-hd track, didn't gave the same results. Feeding both decoders with the dts core of that track, didn't gave the same output also. So, either they don't use the same code, or something else is happening. Last edited by nautilus7; 10th June 2008 at 17:25. |

@Madshi,
Hi again, I know this is a bit of a basic question, but there is a small debate over @AVSForums over whether Eac3to automatically applies the delay shown in the audio filename or if it has to be manually applied in mkvmerge. Could you please confirm is the audio delay appplied automatically when a file is demuxed or re-encoded? Is this true for both Blu-ray and HD-DVD? is there a still a bug where for some titles this does not work? How do we know? What action should we take if this problem does still exist? Thanks. |

I don't get it: If I demux an audio stream which has a delay with sth. like tsmuxer and then process this stream with eac3to, will be the delay ignored or not?

if you dont use eac3to for demuxing or encoding from the source then you have to add the delay yourself, because the delay is determined from its position in the source. so when you use another program for demuxing the audio and only after that use eac3to for encoding then eac3to of course doesnt know how the relationship of that track in the source to the video stream was.
