SR= Surround Right
BR= Back Right

Lovely. But which of them corresponds to the extra channels from 7.1 vs 5.1?

got a DTS 5.1 track here, eac3to reports it as DTS 5.1, while PowerDVD says it's DTS-ES 5.1

so which is right in this case?

Just DTS, possibly with the ES extension stripped?

Rear (or back) channels in 5.1 are shared to back and surround in 7.1.

So you say both have the same content? (SR and BR)
I analized the peaks and they are very slightly different.

I just got the Wall E Blu-ray and it's supposed to have DTS-HD Master Audio 6.1 but eac3to shows only 5.1.

I was wondering what the "($f)" is under Active speakers.

Edit: let me clarify, the box says 5.1 DTS MA but blu-ray.com says 6.1 DTS-MA and several reviews have indicated 6.1 so maybe I'm just reaching for something that just isn't there...

Madshi, those changes are large enough to make it useful to process my audio files again (96/24 -> 48/16)?

hi madshi

when i encode an audio stream (e.g. audio.thd+ac3) to dts, in first the audio stream will demux to 6 wavs and after dts encoding the 6 wavs were deleted.

its possible to keep the 6wavs?

Another "trick" is to set the file flag to Read-Only AFTER the dts conversion starts as the wave files will be complete.

If you just need the wave files, then you can just do as already suggested and convert directly to waves.

madshi, could you please implement a kind of detection which reports 2.0 tracks being mono or stereo tracks? would be useful for older movies, sometimes those original tracks are either 1.0 or 2.0 mono. then it would be possible to distinguish if a studio included an original 2.0 mono track or if they did use a modified stero track.

I can pipe the output of the play list to a file, but it's back to having to clean up those files from all the extra CRLFs.

Also, one other request if you have time. When I'm running an instance of eac3to that's extracting or whatever and then run another instance just to log and get info about another title, the -log doesn't work. It seems to just copy what's already there from the first instance. It would really be helpful if the logging is done independently in each eac3to command.
Will see what I can do...

Regards.
& lemme knoe if u found noticeable diff.
The DTS-HD track is only 16bit, while the TrueHD track is 24bit. Also there are more differences: The TrueHD track is slightly louder and the LFE contains much higher peaks compared to the DTS-HD track. Don't know why that is...

Then remuxed audio and video back to m2ts with TSMuxer. Now there is really low sound volume with remuxed m2ts (I need to tweak the volume in my Yamaha receiver nearly to max so that I hear any sound, with original m2ts sound level is fine). Anyone know whats causing this?
Try playing the demuxed AC3 file as it is. Does that work alright? My best guess is that the AC3 decoder you're using doesn't like 640kbit/s. Some (older) decoders have problems with that bitrate, because DVD was limited to 448kbit/s.

can't say though if this is a specific problem of this single file or a general problem of 2.0 ac3 tracks. only had a 5.1 ac3 track to compare and that one played normaly after wave conversion.

edit: just noticed the track is from a mpeg2 cap and according to mpegrepair 5.1, while eac3to only recognizes it as 2.0
eac3to currently doesn't like mixed 2.0/5.1 bitstreams. I have such bitstreams on my todo list. But it doesn't have a very high priority, because usually if you have such a broadcast, home cinema freaks like us replace the audio track with a DVD audio track, anyway. And DVD audio tracks are usually straight and not such weird 2.0/5.1 mixtures.

Seems to work for me with my latest (work in progress) sources. Can you please retry with v2.78, once it's out? If the problem still occurs, a sample (with which I can reproduce the problem) would be helpful.

Now my question is, in case of 7.1 track, which are the extra 2 (compared to 5.1), SB,SL or BR,BL?
I'm confused. The latest version should use SL/SR for 5.1! Which format does your audio source have?

In case of a 7.1 track, SL/SR are the channels intended for the side speakers while BL/BR are intended for the back speakers. In case of a 5.1 track, the surround channel pair can be played through SL/SR with the back channels not playing any sound. Or you can use some funny algorithms to upconvert 5.1 to 7.1.

If you play a 7.1 track on a 5.1 speaker setup (or if the studio downmixes 7.1 to 5.1) the 5.1 surround channel pair usually contains a mix of the 7.1 SR/SR and BL/BR channel pairs. It doesn't matter much whether you name the 5.1 surround channel pair SL/SR or BL/BR. But IMO SL/SR is the correct name.

AC3->WAV is not simple demuxing. It's demuxing+decoding, which is much slower than simple demuxing.

so which is right in this case?
The track begins with DTS 5.1, but after a while it mutates into DTS-ES. eac3to only checks the beginning of the track, while PowerDVD probably updates its status display all the time while playing the track. So is this track DTS 5.1 or DTS-ES 5.1? Neither nor. It's a mixture of both.

I was wondering what the "($f)" is under Active speakers.

Edit: let me clarify, the box says 5.1 DTS MA but blu-ray.com says 6.1 DTS-MA and several reviews have indicated 6.1 so maybe I'm just reaching for something that just isn't there...

Code:
- activeSpeakers       C L R Ls Rs LFE ($f)
The reviewers often simply report what is printed on the box without double checking it. The Wall E track definitely begins as only DTS-HD Master Audio 5.1 ES. I only have a few MBs of the audio track, though. Maybe after the intro it changes to 6.1? I don't know.

The "($f)" is the hex value of the "activeSpeakers" bitstream element. What it means is shown in the log, namely "C L R Ls Rs LFE". These are the speakers contained in the DTS-HD track. You can see, there is no Back channel in the track, just plain 5.1.

I do not know. I'm still waiting for a reply from a guy who compares a lot of resampling algorithms. I hope that the new parameters are slightly better, but I'm not 100% sure. They could also be slightly worse...

Don't know how to do that. Do you have a few 2.0 mono samples?

CAUTION: Decoding this track with ArcSoft results in low volume.
Which movie is that? The warning means what it says: The ArcSoft decoder decodes this track correctly, but it lowers the volume a bit. You can more or less undo the volume change by adding "+3db" to the eac3to command line. However, perfect losslessness is lost in any case.

Why does ArcSoft lower the volume? Don't ask me. It's caused by the speaker mapping the studio has chosen. DTS-HD supports a big number of different speaker mappings for 7.1 streams. There are at least 3 different mappings the ArcSoft decoder decodes perfectly. But this specific speaker mapping used for this track seems to confuse the ArcSoft decoder, which makes it decode the track with lower volume. It's not a terribly bad thing, it's more or less similar to the effect DialNorm has. If you want, you can report this problem to the ArcSoft guys (together with a small sample). Should be easy for them to fix. Just ask them to decode the sample as 5.1 and then as 7.1. The 7.1 decoding volume will be lower, which doesn't really make any sense. With almost every other 7.1 track on the planet the 7.1 decoding volume is not lower. You can use "-logdts" to see which speaker mappings a specific 7.1 DTS-HD track uses...
