whats the best solution again to deal with 7.1 DTS-HD MA tracks which are described as "strange setup" ? I want to convert the track to flac, so what are my options here?
is this information here still correct? http://forum.doom9.org/showthread.ph...93#post1361493 using sonic to convert it to 5.1 makes most sense atm? Last edited by Thunderbolt8; 29th June 2010 at 17:05. |

Here is my scenario: 1 - eac3to to demux video in MKV container and convert audio to AC3 2 - TsMuxer to mux audio and video in a M2TS container 3 - playback of the M2TS file with the PS3 Video is H.264. When the file is decoded by the PS3, I have many macroblocks, and the result is the same whatever the version of eac3to (3.18, 3.21 and 3.22). If at step 1, instead of demuxing video in MKV container, I demux the video in a H.264 file, then the playback with the PS3 is fine without macroblocks. Note that all these files (M2TS and MKV) are played correctly on the PC. So the problem is relative to the usage of MKV container, either when produced by eac3to, or when used as input by TsMuxer. And the problem is noticeable only when the final file is played with the PS3. Now that I discovered this problem, I will of course avoid using MKV container.

I've extracted the TrueHD track from Evangelion 1.11 blu-ray using eac3to. ffdshow reports it as having channels as shown in the screenshot below.
Note the presence of the side channels and absence of an LFE channel. In actuality, there are no side channels but there is an LFE and a rear center channel which I suppose would make this a 6.1 track (rather than the 7.0 I'm getting from ffdshow). Using the mixer, I found the LFE channel is playing from what ffdshow thinks is Back Left (all that comes out of BackL is rumbling). I'm not sure where the bug is, if it's in eac3to or ffdshow. Any ideas on how to pinpoint it? I made a similar post on the ffdshow-tryouts forum to stir up some suggestions there as well. Here is a short sample that has a pretty good demonstration. http://www.mediafire.com/?mmzydemji5m |

the same reason why 24bit is converted to 16bit. Human hearing has limitations.

however I daresay eac3to "is less unreliable than" ffdshow. I'd recommend converting the original 6.1 audio to a 6.1 .WAV (assuming disk space is not an issue...) Quote:

You know this might be a n00b question but I still don't understand exactly what a digital speaker is and what connectors are used with it. In a normal home theater setup where, for example, a htpc is outputting digital S/PDIF audio via HDMI (coming from the sound card or mobo sound module built-in to the graphics card), then is transmitted to the receiver all through a single HDMI cable, then then the receiver processes and decodes the audio if bitstreaming. But after that doesn't the receiver send a analog signal to the actual speakers? I'm totally confused about this. What exactly is a digital speaker and what is an analog speaker? What sort of connectors does a digital speaker have?

Thanks to some "oddities" of the English language, and also thanks to the marketing people , the word "speakers" became somewhat... undefined. From what I've read so far, it's never very clear when the word loudspeaker refers to the (so-called) "driver" itself, or to the "box" (enclosure) which contains one or more "drivers"... Anyway, usually the expression "digital speakers" applies to a set of "powered" drivers which includes a Digital2Analog converter. ACTUAL digital speakers are an entirely-different beast, and there is an article on Wikipedia about them. HTH.

No such issues with the HDMI outputs. The signal from the AVR to the speakers is always the same (analog) but can be degraded with lower quality wire. But even modest 24GA wires should have no problems with 192Khz at very short throws. Always use 12GA wire for optimum quality. |

Decoding this 6.1 DTS-MA track with eac3to 3.22 and Arcsoft 1.1.0.7 results in distortion: http://stfcc.org/misc/7channels.dtshd
