eac3to - audio conversion tool

thats what I was refering to, I was using wavepad. but is the beginning of the ac3 track, for example the same tone or note, exactly the same beginning of a flac track as well? as it was said, flac has a higher quality/bitrate so this 'more' must be manifested somewhere in the graph?

eac3to reports this file as 8 channels, tsMuxeR on the other had reports as 6. I had this issue once before, after remuxing with tsMuxeR my PS3 & receiver still recognized my movie as 7.1 channels.

Hope this helps.

Definitely. I just got the bluray directory structure ripped on HDD and work with that. Took few mins to extract simple .ac3 file :-O

Thanks, but I actually wanted to FLAC the stream so that I can play it on my HTPC via HDMI to my 7.1 receiver as we can't transmit DTS HD or TrueHD directly today from a HTPC (and I am just looking for direct output from graphic card here, not some Asus Xonar stuff which can maybe also do that, not interested). And FLAC files are also aways quite a bit smaller than the original DTS or TrueHD ones

I hope madshi can find the bug in eac3to, then I am more than happy This is also the only file which has failed so far btw...

It has.

Oops, I guess I should have read earlier in the thread instead of assuming... didn't realize you need FLAC. Sorry then, I cannot help. Good luck.

Then, please, you can help me making a new set of dts test files using this sources?

Mh....as i say Arcsoft -7 on dts es matrix tracks works not with all tracks ive tested so far. eac3to/arcsoft crashes sometimes with -7. (works fine in 5.1) It crashes on all dts es matrix Tracks with phase shift Option enabled ( from dts pro series encoder)

Maybe its the phase shift in dts es matrix track and arcsoft cant handle 6.1 output in this case? I will test it when im at home. That would explain why some dts es matrix tracks can be decoded with arcsoft -7 and some other dts not (with a crash)

[Anacletus]

Hi all, maybe a dumb question.. i have a BluRay with a Dolby trueHD track i want to extract.. i've read a lot here but still im confused on what to do..

Should i extract the THD to flac and then convert the flac to ac3 640? or should i extract the thd+ac3 and just use the ac3?

Any suggestions will be more than appreciated

[QUOTE=madshi;1207948]Don't trust in what PDVD says. Run "eac3to demuxedtrack.dts". What does eac3to say?/QUOTE]

It says: DTS-ES 6.1 1536k... so that's OK. PDVD must be wrong...
Thanks.

[a02] This track is not clean. Processing aborted.
[a02] Please clean the track with delaycut and then retry eac3to.
Aborted at file position 16853820240.

madshi, can you add a switch to ignore or skip over these types of errors. The only time I ever get them is with Blu-rays, and that message doesn't occur until the VERY end of the file. The error reported above is actually the very last byte of the entire file (total size: 16,853,820,240 bytes)

If the error could be skipped over I doubt it would affect the playback sync.

IIRC, the answer given for this question was "don't worry", but worry I will...

When I demuxed a BD, the PCM "remapped" channels.
When I convert the PCM, it says "oh, this from a bd" and again it "remapped" channels.

So, under which cup is the walnut? I thought the first remap was from bd format to a standard windows format, and moved channels around. So, afterwards, they shouldn't have to be moved around again. I think the channels are now in the wrong location. ???

I have started to get that and it would be good if it was ignored as I have found there is nothing wrong with the tracks. I even tried delaycut but it doesn't help.

[a04] The ArcSoft decoder doesn't seem to work, will use Sonic instead.
[a04] The Sonic Audio Decoder doesn't decode the XXCh channel extension..

It's a 7.1 DTS-HD HR track. I don't want to install Arcsoft so I'll stick with Surcode. The resulting flac is 5.1, what happened to the 2 extra rears, were they dropped or mixed into the surrounds?

Thanks nautilus7. With the new samples from DTS PRO ENCODER y can confirm:

- When make 'Ls Cs Rs 5.1 ES' (ES 3/3.1 matrix) or 'Ls Cs Rs 6.1 ES' (ES 3/3.1 discrete) the option 'phase shift' is available and default to 'yes' (with a standard 'Ls Rs' 5.1 we can't select 'phase shift')

- If 'phase shift' is selected the input channels Ls Rs are modified to:
Ls' = +45º phase shift Ls
Rs' = -45º phase shift Rs

- The mix with Cs is (or LS',Rs'):
Ls'' = Ls + 0.707 x Cs
Rs'' = Rs + 0.707 x Cs

- I always have a crash when decode a ES matrix with -7 (sorry ACrowley I can't confirm your post, the phase shift don't modify this behaviour for me)

madshi,

Just wanted to drop by and to acknowledge once more the amazing work you're doing with eac3to [and also to others who are also contributing!]. The ever-growing feature list is amazing and I regularly come back to the program for all sorts of things.

Thanks a million,
frenchglen
