Has anyone tried decoding the 6.1ch DTS-HD MA track on the Wall-e Blu-ray?
Sonic thinks it's only 5.1ch.

perhaps it only switches to 6.1 at a later stage of the movie.

I doubt it. That's the m2ts for the main title. I don't see how it could change to 6.1 midstream.

EDIT: Could be they released a disc with different tracks in France, of course.

The new "-edit" option can be useful to manually sync audio tracks to movies. E.g. if you need to remove 150ms worth of audio data at the runtime of exactly 30 minutes, you can do this: "-edit=0:30:00,-150ms". Or if you need to add/loop 100ms audio data at runtime 15 minutes, 10 seconds and 500 milliseconds, you can do: "-edit=0:15:10.500,+100ms". You can only do one edit at a time, though. The editing feature should work for all supported audio formats.
I assume this will work like the delay, if I have an AC3@48KHz, it would drop 3 32msec frames if I put in -100ms, and add 96ms if I put in +100ms. I really love this feature, I've needed this for a long time. Now I've got something to fix my encodes that end with random sync problems because of corrupted ts streams, now I just have to figure out how much I need to tweak to get things back in sync.

Yes, that's correct. The new "edit" feature is basically just reusing the same code which is fixing gaps/overlaps in seamless branching movies.

Just curious...

This might be a matter of preference, what would produce better quality audio... A HDDVD with EAC3 @ 1536kb/s with dialnorm or that same track transcoded to DTS @1536kb/s for Blu-ray. Would there would be some quality loss in the conversion or would all of the data be retained?

Thanks.

It's like asking which track sounds better mp3 @ 320 kbps or aac @ 320 kbps (or which is better AVC @ 50 Mbps or VC-1 @ 50Mbps?) Conclusion is that you won't hear any difference. (assuming that your source is uncompressed)
BTW. Transcoding from one lossy format to another always means loss in quality.

Are you sure that you used the correct command line for testing?
Tested again, but with 2.84. And it finds many gaps, so i guess there's nothing to worry about now.

OK then, thanks for the reply.

I have a DTS HD MA 6.1ch track @ 16 bit. When I try to extract the core or convert it to 5.1ch 1.5 MBps DTS eac3to seems to patch to 24bit DTS. Is there any way I can prevent it from patching it to 24bit and keep it at 16 bit. -16 switch works only with RAW/PCM audio I suppose.

First off, I want to thank madshi for creating such a robust conversion program! I'm trying to archive my high-resolution audio collection, and eac3to works great for converting mlps from DVD-Audios, but I can't seem to get it to work easily with my DTS CDs.

I start off by ripping the DTS CDs to dtswavs using Exact Audio Copy. The subsequent dtswavs are detected as having DTS streams and play as they should through directshow filters, but when I try to use eac3to to convert them, it treats them as 2 channel wav files. Here is the contents of the log file eac3to produces:

Code:
eac3to v2.84
command line: "\Program Files (x86)\eac3to\eac3to.exe"  "01 - Tequila Sunrise.dtswav" "01 - Tequila Sunrise.flac"
------------------------------------------------------------------------------
WAV, 2.0 channels, 0:03:26, 16 bits, 1411kbps, 44.1khz
Reading WAV...
Encoding FLAC with libFlac...
Creating file "01 - Tequila Sunrise.flac"...
The original audio track has a constant bit depth of 16 bits.
eac3to processing took 6 seconds.
Done.
If I open the dtswav in DTSParser, it detects the file as having an open bitrate, with a format of DTS 20/44.1 in 6.1. If I use DTSParser to rebuild the stream and save a .dts file, the subsequent dts file also plays fine, but eac3to gives the error "The format of the source file could not be detected.". In case it is relevant, the original dtswav is 34.6 MB and the rebuilt dts file is 30.2 MB.

The only way I've found to come close to completing this conversion is to use VLC to save a multichannel wav file, and then use eac3to to convert that. However, the channels from that appear to be 16-bit, and according to DTSParser, the original is 20-bit, so I'd rather not lose the quality if I can avoid it.

Do you have any suggestions as to anything I could try to get eac3to to detect the dtswavs properly. Is it possible Exact Audio Copy is adding or removing some header information which is interfering with eac3to's ability to detect them?

madshi, can you enter a more finely-grained timestamp for the audio editing? For example, to the nearest 100th of a millisecond? Instead of "01:30:02" can it be "01:30:02.250"?

Thanks!

madshi, eac3to is hands down one of the best designed and supported pieces of software I've ever used. Is there anyway I can donate a little something for all the hard work you put into it?

While 2.84 isn't broken by the title "Game Plan" I've found that the audio isn't correctly sequenced. I'll do some more looking and see if I can make sense of it.

Hmm somehow I missed that. Everything afterwards never used that example. (Signal-to-noise is kind of low in this thread lol)

Thank you, snow kiniggit! You're my *hero*.
